Force Matching 180 Procedure - Hunter Engineering Co
HTML-код
- Опубликовано: 30 окт 2024
- This video details an alternate procedure to ForceMatch a wheel/tire assembly. Instead of measuring rim runout with lasers or dataset arms, the tire is turned 180 degrees on the rim. This allows the computer to calculate the position of the tire on the rim that will give the best possible ride.
How do I make it so this is the only man who ever touches my tires?
You would be better off buying these two machines and doing it yourself. Maybe AI one day will get rid of the idiots that change tires in these tire shops.
fantastic machine. to bad the majority of the tec's will never take the time to do this.
exactly.....Called a new Discount Tire in Olive Branch MS...They said oh yes we road force balance every tire we have brand new 18k dollar machines and we do it every time......I get there today to have tires put on my truck and they have 4 different kids one for each tire changing tires on my truck, not a one ever used the road force wheel on my tires till I brought it to the attention of the guy working the counter and then they did not even do it right..... What is the point of having an expensive machine and not using it to lessen the chance of having a customer return because they have a shake at a certain speed. Piss poor training and management of a store.
I absolutely love the GSP9700....wish every shop had one. If we could just train techs better on how to use this equipment
@MrChad97Z same discount tire is cheeks I'll never go there again!
I called Hunter and spoke with a local service rep and he told me that the machine provide excellent training but the problem is that once these techs are cut loose into the shop and now one is looking they will cut corners. It's just damn near impossible to get folks to do right.
No tire shop will spend that much time and care. They will lose too much time and money. Great technology though
The better shops do! Thanks for the compliment.
There are tire shops that do, but it’ll cost you.
My local shop charges $15 a tire to road force balance them. My car had 2 tires with like 30 something pounds and they got it down to 10-15 and it made a MASSIVE difference
@@HunterLearningChannel Can you name some?

@@tonys9731 I just got mine done by a shop in Liechtenstein. Nice technology
Wow this is boNkerzzzz!!! 😅 I love the tech and I wish my shops locally would be able to do such a task but I’m sure it would be about double what I’m already paying for currently for the mount and balance !!!
Approximately how much of an improvement does the bead massage provide? Does it do the bottom bead too?
it will improve the out come and yes it does do the bottom bead.....but getting someone to do it right is damn near impossible.
Is there a place that I should go to get it done? Any suggestions please
you are shooting in the dark even if the place has one of these machines does not mean they will or know how to use it.
Is the point on the tire with the high road force variation generally also the same location as high radial runout of the tire?
Also if time is NOT a factor which process gives the best force match results, The 180 method or the quicker method of letting the machine measure rim runout? I mean why does GM insist on using the 180 method?
The stiffest point of an assembly is not always coincident with the high spot. This is why we use the load roller to ensure we are measuring stiffness and not just runout. If the 180 matching procedure is carefully followed it is the most accurate method of ForceMatching. This is why GM requires the 180 matching procedure.
@@HunterLearningChannel that makes sense thanks for the reply.
Let’s assume the 180 matching is correctly preformed and let’s assume we also have a new version road force machine like an RFE10E with cameras and laser etc to profile the rim correctly. On average how far off in accuracy percentage is the rim profile method vs 180 match method? Asking out of curiosity because 180 method takes twice as long and is it really worth it?
Thank you 🙏🇱🇷🇲🇽
great machine😎
You don't show the part moving the tire mark to the valve stem on the tire maching.
I brought my VW Touareg to Precision Automotive in Endicott, NY. They roadforce balanced new tires on fairly new wheels and I had steering wheel shake afterwards. After a second roadforce balancing the shop mech. said the weight were off by 1/2-3/4 oz. and the RF #'s were 49,45,44,24. He said he couldn't get them any lower and said my tires were garbage. I know the mech. didn't follow the instructions in the video because he never broke the bead of the tires to rotate them for an optimal setup. Now the steering wheel shake is worse over a larger mph range. I think this technology is great but negated when mech.'s don't follow or understand the proper procedure. Most of the time it's a save time and money thing for the shop.
Wow - small world... I used to go to them exclusively because of this machine but I also think they didn't use it to its full potential. Got a lot of wheels with counterbalanced weights. They also helped me warranty "bad" tires with "high" road force, only for me to find that the tires were fine when I returned them to Tire Rack and they measured the road force. Precision measures road force but never corrected it. I ended up getting my own tire equipment because of this place, the price was astronomical for imperfect balancing work.
yep you had lazy ass tech that did not know what he was doing.
Is it possible that a tire can be in such condition that a correction is not possible and the tire must be replaced with a new one?
Thank you for the question. It is possible that the tire may need to be replaced, and it is possible the wheel may also have too much runout (it is out of round). A Hunter RoadForce Balancer will help diagnose inconsistencies in tire and wheel, and the Force Matching procedure will guide the technician to turn the wheel on the rim to minimize Road Force to get the best ride. If an acceptable solution cannot be found then tire or rim replacement must be considered.
@@HunterLearningChannel can an alloy wheel that is out of round be fixed ?
@@mo7ammmad2012 Some companies offer alloy wheel repair equipment, but there are limitations as to what can be repaired. Since we at Hunter Engineering are not experts in this area, I would consult a specialist in this field to find these limitations.
Thank you.
Looking for somebody to help me out here. I replaced all tires on my 2016 VW Touareg and have had a vibration and slight steering wheel shake above 70mph ever since. According to the techs, all tires road force balanced fine. However, they are nowhere near in the teens of road force. I think the lowest one I saw was somewhere around 24. I know for a fact one was at 30. Is there a standard for the road force measurement? I am taking my vehicle to Discount Tire tomorrow because I read that they have a Hunter RF Elite. I am hoping I can get this to match mount my tires to rims.
How did it go? You really have to call around and ask the shops if they are willing to match mount the tires REGARDLESS of what the machine says is acceptable, the lower the better. I found a guy locally with the Elite machine and he match mounts every single tire. It is often overlooked and takes literally 10-15 more minutes at most per tire and can make a HUGE difference. You don't really have to use the 180 matching procedure with the Elite machine. All the technician has to do is press the RoadForce icon and a screen comes up telling him the optimal position of the tire on that specific wheel. This is not the case with the other versions of the same balancer as they use mechanical arms to determine the runout, etc.
good luck... yes your numbers were way off.
My local shop has the Elite machine. I specifically asked them to get the RF numbers to 10 pounds or below, regardless of what the machine said was acceptable (which I believe is 20 pounds). They said when an assembly is within spec (which all of mine were), they cannot reduce the numbers any further except for a few trial and error tire spins on the wheel, and even then the RF number might get higher. Is this true, or is there a way to bypass the machine's tolerance and ask it where the best position of the tire/wheel to get the lowest RF number and the smoothest ride?
Derek-
Thanks for the comment. Let us try and shed a little light on the capabilities of our machine. Yes, Road Force can be reduced below the tolerance if the tech chooses and the assembly is capable of it. That being said, it does get progressively harder to make improvements as the values get lower.
he's yanking your chain. the machine shows the # and it is up to the tech to see if they can get it lower by using the machines correctly.
