It’s not necessarily that the tires aren’t round, but a rim that is not turned from a solid piece of metal is not going to be truly round.

what is the point of shaving the tire tho?

@@rickjames5998 The tires are not "round" when they come out of the mold. As you can see in the video, he is trimming off the high spots. After a while he will not be trimming off little chunks, but very thin long thin strips, similar to peeling an apple. After this, you balance. Driving down the freeway makes you wonder why you never did this before.

@@rickjames5998 On a track day, with a car that has no abs, I have braked too hard while going about 180kph, my front right wheel blocked, and caused a flat spot on a tyre. Ive tossed one tyre already because vibrations were not bearable. Year after same thing happened but i was far quicker to release the brake, causing only minor flat spot which causes vibrations over 100kph. It is bearable now but still shakes the whole car, this method on the video would fix that tyre, as it still has plenty of thread life left. Sadly no shop around has such machine.

Your video is terrible!

Your method is very unsafe and could cause serious injury and shouldn't be done the way you did it.

4x4 needs same outside diameter measurement so that transfer cases and differentials don't fight the rotation of different sized tires.

@Peter Slogan umm... road force would be almost zero if the tire is shaved and then put on a road force machine to check for road force feedback. All radial run out is taken out no matter where the tire is at on the rim when it is a shaved. Imagine not having to mount, dismount, and remount a low profile tire (hoping you can get the tire to right spot because it won't move when mounted) on to only take out some of the road force feedback but not all of it. And hoping the rim doesn't spin on the road force machine, the rim must be marked to the machine prior to road force balancing or improper readings occur. Shave it.

Hi Rahul: We wouldn't know the anwser to that. But, you can spin up the tires and see if they're out of round in most cases, if you have the shop, or you, raise the tire in the air and spin it. If it's out of round you can generally see it visually while it's going around. If it is, and no tire truing is available in your area, you may also find that the shop might be able to re-mount the tire on the rim in a new position, like 180 degrees from it's current position. That can sometimes correct the problem. But, if the car has been sitting for a long time, sometimes the flat spots on the tire just need to be driven for a while to get them out. Try finding a shop in the area that has a Hunter Roadforce balancer if it's a car, or a Hunter Forcematch balancer if it's a larger truck tire, and see what they can do for you, if no tire truing is available in your area. Roadforce and Forematch are patented trademarks for machines that Hunter Engineering makes, that can sometimes correct balancing issues at a higher level than a typical tire balance machine can. But, if else fails, you may have to purchase new tires, if no tire truing is available in your area.

Thanks for your response Mark. The tire I'm trying to get shaved however is a new one so it has no imperfections. The reason I'm trying to get it shaved is that I have an AWD car and the new tire has a tread difference that's making my center diff unhappy in the lower gears. I haven't been able to find a shop here in Dallas unfortunately. I might have to trade in my old tires for new.

Right, okay. I've been told that Tire Rack will shave a tire to your spec's if you ask them to. If you have a Tire Rack in your area you could give them a call and ask. If so, and if you haven't mounted the new tire yet, whomever you purchased the new tire from will likely refund your money, I would think.

I know this is 5 years old. But have you ever figured out the answer? I’m in the same boat and don’t want to replace all 3 tires when one blew out.

We ended up buying all new tires.

@@easygoingday8980 Yes, shaving a new tire down to match the other three will keep you from having to buy a full set on an AWD car.

@@earlbrown yeah, I’m aware of tire shaving, but I literally don’t know ANYONE who does it lol. Ironically, I just got a nail in my sidewall today… I need to replace 1 tire or all 4 tires because I got AWD :/

@@easygoingday8980 Same. I finally bought at tire shaving machine a week ago for myself. Thought about trying to make money with it, but it'd probably be a waste of time since nobody has ever heard of tire truing anymore. And I life in the south where there's big ass trucks all over the place with cupped mudgrips (and donks on shitty taco'd wheels)

Dashcam Dumbasses I would find a cheap set of steel wheels to mount the winter tires onto. Will save you money on the long run and if you’re already storing the tires it makes no difference

Thanks. Interesting that no one in your area can do this. You might have to travel a little. It's not new technology. Another thought is, try calling around to find a tire shop that has a Hunter Roadforce balancer, and they may be able to balance at a higher level that most balancers, which might take care of your problem.

No body within atleast 2 hours of where i live can true a tire. 1 place does have a road force machine. I used to work there. But they basically never used it. They are a regional chain called Dunn tire. Around buffalo ny area. And they just want cars in and out. It was ridiculous. My old manager there expected us to mount and valance 4 tires and have the vehicle in and out within 15-20 mins. Worked like a dog all day. Got damn good and vast at doing tires tho. Haha. Messed my elbow up for life from that stupid job. And they only want you there to work in the rush seasons. Spring and fall. For all the winter tire changeovers... We actually used to store everyones winter tires during the summer in a giant upstars warehouse area. Minimum wage job. Horrible. But where i live sometimes you just gotta take any job you can get for the time being.

More or less. If it's out of round you won't want to drive on it very long. Or, you may have an all wheel drive vehicle and a tire hazard issue and need to replace one tire. You could buy all four so that they'd all be the same outside diameter, as is required on all wheel drive vehicles. Or, you could just buy one, shave it, and save a lot of money. If the tires have little tread on them already, it makes sense to just buy new tires all around.

Also, driving a car with new tires that are no round is pretty easy to diagnose, and nothing you can do except for truing them. Some tire manufacturers will take them back if you haven't driven on them much. Sometimes you'll find a vibration can't be fixed with balancing alone, if it's because of tires being out of round. This is an old technology solution that still has its applications.

Simply warming the tire up similar to driving down the road a short distance. Eliminates the flat spots and warms the rubber so the cutting operation gets the best (most concentric) results.
