    • @3rdpartyU5er
      @3rdpartyU5er 9 лет назад +5

      +AustrianAnarchy Well this is just my opinion but wider wheel means more surface area for the tire but I would assume that the tire still loads weight pretty good and suspension geometry wouldn't change drastically.

    • @AustrianAnarchy
      @AustrianAnarchy 9 лет назад

      3rdpartyU5er I should have been more specific. Wondering about the load on the bearing. Pretty sure if the center goes out farther that creates a bigger load on the bearing, but if it stays in the center or is moved in closer to the hub is either of those bad too?

    • @3rdpartyU5er
      @3rdpartyU5er 9 лет назад

      Well it depends on the centre hub of the rim because as you said it yourself as the hub goes further away the bearing gets more load but then again depends on the rim because there are quite a few different rims that have the hub on different location because of the width of the rim. You have no worries if the wider tires have the hub on same position as in stock tyres and what I mean is that you measure the hub distance from the inner end of the rim to the hub. So the wider wheel may be the same as stock wheel but after the hub the rim has a bigger lip for wider rubbers. This should not stress your suspension.

Giving me about 3 inches of drop on a 2012 mercedes c250 coupe. So thats 3 inches and a much stiffer suspension... I've had the car this way for like I donno 2 years or like 50,000 miles... the only problems I had was I tore the boot on my cv joint in the back, (rear wheel drive) and the subframe bushings are pretty shot... but my bearings are fine! The car is fine... this smells like a hater video... but I appreciate it and I love all EE videos..

    Years ago when I was about 8, I can remember helping ( more likely hindering) my father to jack the family car up and put wheel spacers on it. He did this every summer just before we hitched the caravan on it to go on our holidays. Only more recently did he explain, that he did this to add more stability to the rear of the car whilst towing the caravan. As soon as we returned home we would jack it up again and take the spacers back off. Even back then I recall the car looked skinnier once they were off again, but, for him, that was their purpose. I came here for information and I got plenty! Guess I will leave my car as the designers intended now, as there seems to be less advantages for and more against doing it.

I have been running 2" spacers on my 2008 GMC 2500 HD Duramax Truck for the past 7 years. With a V-Plow, salt spreader and 2,450# of salt in the bed of the truck. Still have not had any problems with suspension or wheels.

    After adding 15mm spacers to the rear of my car, I've noticed a significant difference vs. them not being there. With the spacers, the rear suspension feels a lot softer, almost too soft, so confidence in the corners is reduced. The car looks better with them on, but I think I'll be removing them soon.

    You should have also mentioned that it has the same effect on the wheel bearing as if you just got bigger wider tires is the exact same stress on the wheel bearing rather it's done with the spacer or just plain out bigger tires and rims so take that into consideration when making a decision

  • @russianpegs
    @russianpegs 9 лет назад +35

    for the last point, even without wheel spacers, if the wheel has more offset it'll wear the bearings out faster.
    but if the wheel is wider towards the center of the axle it could compensate the offset and thus have normal wear characteristics.

    • @tobiasfrei6262
      @tobiasfrei6262 4 года назад +2

      Pyry Mustonen Let me explain what he meant. I for example had 18x7.5 with 45 offset. I bought aftermarket wheels 19x8.5 with 40 offset. Due to the wheels being 1 inch wider but only 5mm less in offset, my wheels stick out around 18mm more. Therefore my wheels are also around 8mm wider on the inside, which results in less space between my suspension and my wheels, but also less leverage on my bearings

    • @zokusharuuku1091
      @zokusharuuku1091 2 года назад

      Very true but in the case of spacers not wheel offset the wheel doesn’t get wider. If you do spacers and wider wheels the wheel is still push outward more which still moves the center of the wheel out further from the car.

    • @RobertKarlBerta
      @RobertKarlBerta 2 года назад +1

      The major issue with wheel spacers is the safety factor....bearing, scrub radius change, loading of springs, etc ALL negatively contribute to possible problems that can result in an unsafe car. A wider wheel can give the same issues but often those wheels are wider both on inside and outside so yield the same tire position relative to stock. In many countries use of wheel spacers is illegal. If you think you are a better engineer than the people that designed your car...go ahead and mess with spacers but I would never use them on my SCCA race car or my street cars. Just get a PROPERLY specd set of wider wheels and tires.

      some things you just have to accept you will replace. I know a few hardcore racers, on wheelbearings for instance they plan on running through 2-3 sets in a year. and sometimes Modifications dont change enough to make much difference. It is a good point though, especially on a daily driver. then theres the stance crowd that thinks sparks coming off an undercarriage is cool, and run camber that grinds through bearings at an alarming rate considering they are on public roads and most are too cheap to keep them fresh.

    • @wjh3207

  • @C3kPanda
    @C3kPanda 9 лет назад +5

    The biggest threat of wheel spacers is indeed the change in Scrub Radius and in Kingpin offset. In short: you could be altering your NEGATIVE scrub radius to a POSITIVE radius, with the result being you slipping all over the place when one wheel is on a surface with less friction (Icy spots, gravel, etc.). The other problem lies with your increased kingpin offset and having a lot of power driven to the front wheels, which results in massive torque steer.
    Hope it's any help!

    However, the overall track was pulled in quite a bit. The spacer just pushed the thinner tires out to the original track width (outside to outside).

    just an FYI if you align it and fix the caster then turning won't be as difficult and the tire wear won't change. you may need to change some arms to adjustable arms so that you can get those adjustments, but then it will wear the tires properly. I run an alignment shop with 30 years of experience there, we can get tires to wear properly no matter what kind of mods you do to your car.

      You should probably do a video on caster and the importance of it, also for those who like to camber their wheels way negative, explain the issues with that. Less rubber contact, tire wear even with compensating toe for camber, easier to hydroplane the car, and many other issues for ride quality and handling.

    • @jaredweldy
      @jaredweldy 9 лет назад +2

      Engineering Explained but I will say not a lot of people will catch the fact that the bearing will wear faster with the issues of spacers... another idea is the huge rims issues... I aligned a car that had 26" rims, we had to weld and reinforce both sides of the frame (the frame was broken on the right front where the lower control arm bolts on due to the wheels), replace all ball joints and tie rods due to the excessive size of the rim it was wearing it all extremely fast since the small car wasn't meant to handle that force of turning when moving with the wheels. Just trying to turn the vehicle while going 25 was extremely suprising. The centrifugal force of the rims make you slow down considerably to make turns otherwise it won't cut it. Plus the rotors were warping and needed a big brake kit or really good rotors to avoid the warping when trying to slow the car down. The bill came to about 3k due to the hours spent on it.

    Remember that adding a wheel spacer is the equivalent to going to a wheel with a different offset.
    Also, the wider track allows more stability during those off-camber situations when you are out wheeling.
    The cheaper wheel spacers are often not hub centric, so they can potentially put undesirable loads on the lug studs and result in more radial runout.

      @@banimanFJ that is a very good question. I do not have an answer, but your mode of the thinking sounds correct.
      I never bothered to figure it out to be sure, but I believe that per the original design of vehicles, the steering axis is intended to be right in the center of the wheel/tire and you want to stay in that vicinity as much as possible. Why? How? That's for the engineers to determine. I am not smart enough to know stuff like that.

  • @ellomurz

    A few weeks ago, I installed some wheel spacer but recently I removed them. The main reason is because I just didn't trust them on my car, I felt like my wheel was going to come off when driving. I did install it properly, there were no crazy vibrations. I noticed my car performed better with the wheel spacers off vs with them on. My car drives more smoothly with the spacers off. If you look at the risks vs benefits of having wheel spacers, I personally feel the risks are far greater than the benefits.

  • @sodazman

    Having hub-centric spacers is the same as having low offset wheels. Most people say they are bad but I have personally seen some of the fastest race cars in the world use them to great effect. Some of these cars generate in excess of 1000kg of downforce and i have spoken to the engineers and they have not seen a single bearing failure. Porsche even supplies them as an option on some of their models.

      The fastest race cars in the world are also usually rebuilt with completely new bearings (not to mention valves, spark plugs, pistons, shocks etc) so frequently that it isn't allowed to become an issue -- in some cases after every single race. They never see failures because the components that could fail are never ran long enough to even come *close* to failure let alone performance-degrading wear -- unlike your average "tuned daily driver" that will see 15,000 street miles a year but only ever have the wheels off when it's time to put new brakes or rubber on.

    wheel spacers can also decrease the scrub radius (and everthing associated with it) as some cars have king pin geometry that puts the scrub radius to the outside of the wheel centerline. Also, the spring rates affects, and everything else mentioned in section 3 after the king pin/scrub radius part, is affected about as little as the lateral load transfer. The only affect a driver would feel from wheel spacers is the scrub radius change, everything else is too small of a change to feel from behind the wheel (although your wheel bearings may feel it).
    Also worth noting is everything mentioned in this video is general wheel offset information. For example if you have a +10 offset wheel and a +20 offset wheel with a 10mm spacer (all else being equal), both wheel will have the same affect on the rest of the car and geometry. The +10 wheels with no spacers aren't gonna magically put less load on your wheel bearings. I know this part sounds simple but I've had to explain it to a surprising amount of people.

    Another related issue with wheel spacers that didn't get mentioned - When people use wheel spacers that are thicker than the amount of length the hub center is sticking out past the flat wheel mating surface. In such cases, the wheel is not longer in contact with the OD of the hub center, and only relying on the studs for alignment. I know some wheel spacers include a secondary hub center to deal with this, but I see many flat spacers used that don't have this feature, and they seem rather unsafe, given that wheel loads no longer get transferred through the wheel center, not to mention potential alignment issues. Excellent video though, thanks!

    I used to have a Jeep Patriot (too broke to get a real jeep). I wanted to increase my clearance, so I went from 215's to 235's. This definitely gave me better clearance, but had a couple of issues, such as the tranny overheating at high speeds uphill, slower acceleration (but I actually saw an increase in gas mileage when on the highway), but the main issue was my tires rubbing against the wheel well.
    To prevent the rub, I installed 1-3/8" spacers (had to have them custom cut in order for the hubcentric ring to fit in the wheel). Not only did this prevent the wheels from rubbing, it also allowed me to take corners faster than I could previously. Corners that I would normally take at 45 I could now take at 50. I'm guessing this is because the wider track gave me a lower center of gravity. So the pros for the wheel spacers would be to prevent tire rubbing (which extends the tire life and allows a sharper turn radius), and a way to compensate for the higher center of gravity due to oversized tires. However, this is a cheap fix that could cause issues down the road.
    Both of these benefits could be achieved by purchasing wheels with a different offset. My biggest concern is premature wheel bearing failure. If you're thinking of spacers, the question to ask yourself is if you want to pay now and do it right with better wheels, or pay later by replacing bearings. If you're mechanically inclined and can replace bearings yourself, then using spacers is the cheaper option. If not, you're looking at about $200-$300 per bearing, which is about how much you would pay per wheel in the first place.

    I really wish that when talking about topics like this people would also bring up that it’s not just specific to wheel spacers. The same concept applies to aftermarket wheels that have a lower offset as well. I hear so many people talk about how you can’t use wheel spacers because the ruin your bearings; that you should just get wheels in the offset that you want but it’s the same exact thing. People just falsely believe that it’s the spacer that is bad and not the effects that it causes.

  • @Nayr747

    You will also generally need extended lugs with spacers. It can be dangerous when people use the stock lugs since there's less threads available for the lug nuts to grab onto. Aftermarket wheels in the offset you're trying to get with spacers don't have this problem.

    I did a square set up on my E46 M3 and did 9.5 rear tires all the way around for my 27 off set. The fronts stick out more so I added spacers in the rear to help equal it out but they don't make spacers big enough to make it perfectly equal and with at 20mm spacer I rub when going over bumps so I leave it at 15. But going from staggered to a square set up doubles my pilot super sport tire warranty which saves me lots of money well as being able to rotate my tires. With more rubber in the front I can stop quicker and have zero body roll and under steer where I used to have it.

    @rhetth-s8082 9 лет назад

    Glad to see a vid on this but two problems.
    1. Adding spacers does not necessarily reduce the spring rate. It increases the compression forces on the upper arm and the tension forces on the lower arm. The specifics of the geometry of the links will determine whether the effective spring rate is slightly increased or reduced. In a normal suspension the difference would be very minor.
    2. The diagram showing a moment load on the bearings assumes a significant negative rim offset before the spacers are even put on. On most if not all production vehicles the standard offset is positive or significantly positive.

    • @d1sturb3d119
      @d1sturb3d119 9 лет назад +3

      18bagabooo That's the problem then. The instability isn't caused by a scrub radius change. That is a very minute change that can only be felt under hard acceleration out of corners.
      Using spacers creates more leverage on control arms. More leverage means that you change your static ride height ever so slightly. If the ride height changes the alignment specs all change.
      If you haven't lowered your car camber is not an issue. The change in toe is the issue. Look at what the stock specs are and adjust for that. If you like it then keep it or adjust further from there. I guarantee your toe is off by quite a huge margin.
      When I did my car the rear was set to 0.05 toe out stock but then moved to 0.25 toe out after I lowered it. The car cornered very well but was way to aggressive and would lose the back end sometimes.
      Get an alignment and you'll see the difference.

  • @uhrwerks
    @uhrwerks 9 лет назад +1

    Obviously, everything depends on the size (thickness) of the spacer & what vehicle.
    Let's say someone wants to use a spacer on a "top heavy" SUV that does NOT have any stability control, etc. Wouldn't winding the track say 1/2"-1" (?) with a spacer technically help stability because the track is now wider?
    As others have pointed out, what about adding a wider tire (I know going one size wider would not cause any "scrub").
    Lastly, technically, what about the effects of both a spacer & going up one size in width? All with the goal in mind to decrease "top heaviness."
    As far as spring rates, I can get basically an unlimited number of spring types, both factory & aftermarket (stiffer &/or stock-3" lift). The vehicle in question is an old Land Rover.

    Multiple appeals to OE design. Understandable. You said it yourself, OE's are motivated by cost savings. This alone is a reason not appeal to the OE design so much. Your implied force distance for your moment arm on bearing stress is purely based on change from OE. The actual- would be centerline of tire. Right? This is so important for not just spreading more misinformation on the subject. This is also just a static/ driving straight analysis of stress from weight of car. The moment arm for bearing stress based on a changed wheel track changes for cornering. My claim I'd love your take on, is space with spacers or wheel offset such that the center of the tire is over the center of the bearing. For most cars, the wheels would stick out in this case. This is the static equilibrium state where the average force is placed over the center of the bearing. Nothing better. Cars aren't designed this way to begin with. Offsets and spacing can improve bearing life in this state. Is that such a bold claim? Thoughts?

      If you do decide on going with lowering springs and spacers you should install your springs first. Once you have installed your springs you need to drive it for about a week or 2. This will cause the new springs to compress and settle in. Once your new springs have settled in you can begin to measure how much room you have to install a spacer that won't rub.

    When I saw the title to this video, I was wondering if the subject of wheel bearings would be covered? It did to my satisfaction.
    I recall back in the 1960s being first aware of wider wheels having detrimental effects on wheel bearings. In the US Can Am race series, Bruce McLaren had a nearly invincible race car with the McLaren M6A. One of the notable features with the M6A was in its wheel hub design to use wider wheel rims/tires than what were on the Lola T70 race cars. The teams with the T70s copied the M6A with using wider wheel rims on the wheel hubs not designed for the width; where the T70s promptly had problems with wheel bearings failures.

    well done video man. another item to cover is increased rotational weight. rotational weight has a much higher impact of the performance of a car than static weight. while wheel spacers might only add a few pounds per wheel, the impact could be much greater because it is weight added to a rotating assembly.

    • @Dawood4

    One other reason wheel spacers are used are in 4wd oversize tire applications. Mounting over sized tires ( by over sized I mean larger in diameter)) on a lifted 4x4 is fine. However your turning radius may be reduced or restricted because the higher larger tires will now scrub the frame at full left or right lock of the steering. By adding wheel spacers it pushes the tire outboard more in relationship to the frame rails allowing full steering lock without the higher tires scrubbing the frame.

      The negative effects would actually be more notable than the positive ones, since the negatives are produced from a relatively larger change than the positive effects are.
      To better explain, an extra 20mm on either side of the vehicle will increase stance by some incredibly small percentage over the relatively large total distance between the wheels...
      However, the same 20mm added on to the hub will be a much larger change when measured against the individual suspension components, since everything is much closer inside each wheel well.

    Basic rule of thumb is if you change the offset of your wheel or get spacers, get an alignment since all the specs will be thrown off. An alignment goes a long to way to reduce stress and wear on components like tires, the streering rack if its an FWD car and resets the toe which is pretty important. I've been running 25mm spacers on both my FWD and RWD car for 4 years now with no issues as long as the alignment specs are kept in check. Now if you're the type to run 2 inch spacers or something along those lines yes wheel bearings can get worn. As long as you keep it within the fender line there shouldn't be any issues.

      Use TUV approved spacers. H&R does a great job. 5mm is the minimum but they're slide on spacers which are sketchy.
      If it's 5mm, 10mm or 15mm I would highly suggest using longer wheel studs to make sure you have enough stud length to keep the wheel on. If its above that like 20mm, 25mm or 30mm, usually they come with studs pressed into the spacer.
      Do not use an impact hammer to put wheels or spacers on. Use a torque wrench and torque to spec. After 50-90 miles take the wheels off and re-torque them. Retorque your wheels after 50-90 miles as well.

      +vidurc There are SOOOO many threads on the forums about this.. and i have not seen definitive proof that you definitely do or do not need to get an alignment after say a 20mm/25mm spacer install.

    things to consider:
    1.: spacers ar used not just onroad. thing off offroad stuff, it amkes more sense there, actually.
    2.: it does change the ratio of track width and axle distance. witch affects steering geometry allso.

    There is a nearby town (that I drive through fairly often) that will extract revenue from any vehicle with tires that extend beyond the edge of the fender. I use wheel spacers _only_ to compensate for wheels with different backspacing, not to compensate for anything else.

    • @MrTheHillfolk
      @MrTheHillfolk 2 года назад

      Maybe they are doing it wrong ?
      Initially the Germans did it to get around a law about the TREAD sticking out beyond the fender.
      So there's the stretched tire , keep the tread within the top of the fender lip while you have 1-2" of wheel sticking beyond.
      It's a 🖕 to a government restraint the way I see it.
      So not everyone loves that look but I like why the Germans did it.
      I'm not even gonna go there with the who did it first argument.
      So take a look at the stretched tire idiots next time ,and see if it's being "done right".

    Spacer + Rims with higher offset than original rims will not affect (3) Suspension Geometry, just saying.

    • @Natedoc808
      @Natedoc808 5 лет назад

      Lansdrow it would because the lever arm on the bearing is still greater as the studs of the spacer bear the weight and stranger it onto the hub and that interface is farther away from the center axis of the bearing.

  • @MrPaperjazz
    @MrPaperjazz 9 лет назад

    All right but what I would add to your considerations is a confront between the moment you're gonna subject the bearing to with the spacer lever and tyre load, and the moment the bearing is subjected when you're going through a corner with relevant acceleration. Assuming the lateral load on the tyre is the same of the vertical (with a road tyre) the lever would be half of the night of your wheel, so the bearing would be subjected to a by far higher moment.I've never used to fit or advice spacers, but I'm still looking for a relevant reason to avoid doing that.

    if spacers are so bad why do they put them on 1 ton dual wheel pickups their are 6" spacers on the front of mine from the factory

    • @tofudeliverygt86
      @tofudeliverygt86 8 лет назад +11

      If they are from factory you are at least sure that someone thought them through and the components can handle the increased load.
      I also imagine pickups have tougher suspensions than say family cars.

    • @TomBrooklyn
      @TomBrooklyn 6 лет назад +2

      spacers aren't intrinsically bad. the point is that the car is engineered to work as best the designers could make it with certain spacing, and if you change the spacing, the forces become different, and might be suboptimal compared to the original design.

  • @johannienel1
    @johannienel1 2 года назад

    I have been saying this to guys for years but always had opposition telling me it can’t make such a big difference to suspension geometry and bearing loading… well here it’s explained by someone way more cleverer than me 😉

  • @peterlabiak1051
    @peterlabiak1051 5 лет назад +5

    I enjoy watching your videos, sometimes they put me in the right general direction when looking for info! One comment I would like to make is regarding the old chestnut on how "engineers designed the car the best it could be, etc., etc.". News flash, car business is about bottom line and in 99.9% cases. The only driver is how to manufactore it the cheapest and so it doesnt fall apart before the warranty expires. Performance is the last thing on their minds, notable exception are performance models like M-series, AMG, and so on. There are some tests done by enthusiasts in Europe where they gathered together a number of fellow petrolheads owning the same car in different modification stages, perhaps best was m135i test. I write this to respond to your maths line where you claim track widening is neglidible in terms of grip increase. This might be so, I cannot be bothered to run the numbers really. On the same note have you run the numbers on how much difference would an increase of say 20mm per wheel effect on said lever arm force? You would find it negligible as well :)! That's one thing. The other is handling characteristics. Even if your mentioned physics maths calcs prove the theoretical grip increase is low I am pretty confident you would struggle in the handling characteristics department. This is where a driver gets the confidence to push from and times on track drop massively. To sum up the lowest times were recorded by cars with widened track and lowered suspension, not the ones with more power or better brakes. Tyres were if not the same then all of the performance variety. Driver and passenger were the same. Don't get me wrong, I am not trying to knock you and your vids can only be so long. It is worth to perhaps get out from behind the (in front of?) a white board (and you do need a bigger one and perhaps somebody to do the drawings for you ;)) and check stuff in real life. If you are planning to keep driving your car for over 100k miles then do not modify it at all, just service religiously and tune it from time to time. Otherwise stop worrying and slap on those (high quality hub centric) spacers and take great pleasure from better stance and (disputably) improved handling characteristics.
    Keep up the good work!

    @Proj3ctLife Год назад

    I changed almost every component in my 2012 Acura TL suspension. The only thing I didnt change was the lower control arms and steering knuckles up front and rear knuckle in the back. I replaced all 4 hub/bearing assemblies, arp ext. wheel studs, 20mm spacers all around. 19" aftermarket wheels, adjustable front upper control arms and a rear camber kit. The brakes and rotors were 7 months old at the time of install. Axles were replaced too. Tein coilovers were replaced with BC racing DS series coilovers. The car is fully aligned while sitting 4 inches off the ground 😂

      you can always opt for wheels with shorter backspacing. it may be a better option than spacrrs, but anytime you modify a car you're always going to run into little opportunities for increased wear

    • @jasonsulzbach782
      @jasonsulzbach782 7 лет назад +5

      I was thinking the same thing but, hypothetically speaking. if you went with a negative offset wheel to let's say gain 2" wouldn't it affect the geometry of the suspension just as a 2" wheel spacer?

  • @gerardoquirogagoode8152
    @gerardoquirogagoode8152 4 года назад

    explanation sounds fair, although the force will decrease slightly the longer wider the spacers .... agree, momentum increase and eventually bearings will break ... the most important question is: wheel bearings will last 10%, or 20% or 30% less after how many miles ????
