Road Force Balance MT/R's

Anyone had a problem getting their Goodyear MT/R's road force balanced? I've read plenty of threads on here that recommend it, but no one around here will do it. I've always tried to go the whole "buy local" route, but lately it hasn't been working out. (Could be an entire different thread). The local Goodyear dealer here told me he couldn't even get the MT/R's in a 33" size, that they don't make them any more. I called BS on that because Discount Tire Direct had about 20 of them. Of course DTD ended up being where I got them from, they were $400 cheaper on a set of 4 than the only place that could even get them locally. The only Road Force Balance machine in town is at that Goodyear dealer, and now he says that you can not RFB the MT/R because the lugs mess it up. Is he full of BS again, or what? I've called around everywhere near here, and they all say that is the only place that can do it. A couple places even agreed with the guy that you can not RFB this tire. What gives?

I'm at the tire shop now getting them mounted and balanced. I guess I'll have to find a place farther away that can road force balance them later. Anyone know of a good way to search for places that do it?

I've had my current kevlar and previous non-kevlar 35" MT/Rs RFB'd multiple times at Discount Tire here in the San Diego area.

Here's a RFB locator... Hunter Road Force Balancer location finder

Figures... I had called this place before and they said they didn't do the RFB. After I got my tires on and was BSing with the owner about pretty much everything I had said here, he said they just got a RFB machine, that only them and that Goodyear dealer in town do it. He said he can do these tires no problem. He was surprised that I wanted to do this without driving on the new tires. He said they usually only use the RFB machine to fix vibration issues. I said that people I trust online recommend it, and for what I have in these tires, what's $40 more. Lol. I set up an appointment for Thursday.
And for what it's worth, just from the drive home, I LOVE these tires. I can't believe that anyone could call these things loud. These are the quietest tire I've ever had, hands down. Thank you to everyone that recommended them.
Oh, and another thanks to you Jerry, that locator is pretty cool. I'm sure it will come in handy for anyone else that reads this and is looking for a RFB. The shop I was at did show up there, even though some of the employees don't know about it!

I wish my MT/Rs were quiet, they are actually pretty loud so I wear ear plugs during long trips.

My thought is perhaps there was a tire balance or toe-in problem when the previous owner of my TJ mounted them which may have screwed them up. The previous owner said my MT/Rs had about 1000 miles on them when he sold the Jeep to me.

Maybe it's because they are brand new, I guess I'll see. I'm comparing them to 4 different M/S tires that I've gone through so far on this Jeep, and I understand that the M in MT/R isn't for mud... Compared to the mud tires I've had before, even when new, these are unreal quiet.

In all fairness, I guess that I should add that the same employee that told me that they didn't do RFB also forgot to write my appointment down. When I got there at 12:30 they were pretty busy, freaked out when I told them... Jammed them up a bit and I had to wait about an hour for them to get started. The owner blamed his Dad (it's a mom and pop kind of place), maybe it's just old age taking it's toll. Lol.
Oh, and according to my last hearing test at work, my right ear is down 16% from last year... But I still say these things are really quiet!

Hah in spite of my bad/deteriorating hearing complete with tinnitus, my MT/Rs are still really loud. However, I think it's just mine from perhaps an initial alignment or toe-in issue because most kevlar MT/R owners do comment how quiet theirs are.

Are they cupped or feathered,etc? That was what made me get rid of my old set of Wild Country MT's. Those things wore like iron. They were loud to start with, but man they got bad. I couldn't take the shaking anymore, but they had plenty of tread left. I had a few bushings that were bad and despite regular rotations, they were cupped like crazy. Broke my heart when I paid way more than I should have for Baha Claws that wore like butter and didn't even come close to the WC's in snow and mud.

Nope, no visible wear problems with them at all.

Huh, that sucks. I drive a good distance to work and my Jeeps my DD, so I guess I'll post if they start getting louder. Maybe the stickers are just keeping them quiet for now...
While you're here, what's a good trustworthy tire pressure gauge? I think I'm going to get a new one, I have a few and none of them read the same. I'm kinda anal about tire pressure, and give or take 3lbs isn't going to cut it...

I only use larger size analog dial gauges with a max of 30 psi at full scale. That lower top psi gives more accurate indications at the lower pressures we use on our larger Jeep tires.

This is the exact gauge I use...

Cool, thanks again. Good point on the lower top end reading, that's why I bought a gauge for my 4-wheeler tires that only goes up to 5lb. I just checked my collection of normal tire pressure gauges and they all go to 50 or 60 lbs. 2 of them are accu-gauges but don't have the hose coming off of them. I like the idea of the ones that you connect to your air line and they measure when you stop adding air (don't have to disconnect) but I figure they can't be as accurate (air leaking through), and they cost a lot more.

The air pressure that is feeding a tire is much higher than most mechanical pressure gauges can handle. Without much thought, I put a 30 psi gauge on my first octopus tire inflator/deflator rig and my OBA system pegged and broke the gauge its first use.

Lol. Sometimes good ideas fail at first test. I see a lot of that at work. I'd have to look, but I think those ones that connect between the air line and tire are digital. I figure that any leak through in the gauge would make it read high.

I had all my KM2s 35s RFB after i got them mounted and balanced on a standard balance machine, heres before and after pics.. this was the worse one but they all had alot of wheel weight before and less then half after... I also took this wheel in the pic to town fair tire and they told me my brand new rim was bent..... needless to say it wasnt....RFB is the only way to go.....

You all ROCK! Glad I found this out. When I get my MTr's in Cali, I will def get the RFB done. I just need to do the 1500 mile trip there first and my AT's are gonna save me some major coin in gas

My MTRs are pretty quite. Do you not have a Discount Tire close by? The Discount Tire I go to does nothing but road force balancing. They have like 5 machines, one for each bay.

The closest DT to me is a couple hours away. They shipped these free from AZ to WV. As outrageous as shipping is now, I'm impressed. No need to drive 1500 miles, they will send them to you free, you just have to get stems, mount, and balance.

I had the opposite. I had shimmies after multiple tire ballancing on my 33 BFG ATs. I had them RFB and the shimmy went away but ended up with a lot more weights inside and out.

I have/had problems balancing my 35" KM2's
I turned to RF. I way I understand it, it's a normal balance unless there is problems with the tire ie, out of round/ex runout. Then they will proceed to RF but reading the runout on both the tire and the wheel.
Then they will break the bead and spin the tire. I bought my tires used. 2 were close to max runout. 1 tire and 1 rim, the machine actually read "replace"
That tire/rim is now my spare.

They are all " 0 " but I still have vibes. I'm going to try balancing beads although I know they probably won't help with defective tires.

My advice..... No need to RF unless you have issues/vibrations.

I just got back from the tire shop after having the RFB done. It probably wasn't necessary seeing how they were great before and after. I need to drive more to form a real opinion, but they did make some adjustments. Two of the tires they spun 90 degrees, and they either added or subtracted weights to all four. The owner said that the numbers went from the high 30's to the low 20's and he really liked the tires. I need to read more about runout, but does that seem about right? I was hoping for a printout, but they didn't have one.

After reading this http://www.gsp9700.com/technical/5098t/5098t.htm I wonder what reading he gave me when he said they went from the high 30's to low 20's. Either way, I love the tires and can't complain.

Runout doesn't have anything to do with balancing and can't be fixed. A tire with to much runout has to be replaced. For oversized tires with large sidewalls it's pretty much impossible to get a tire that doesn't have some runout. One of my MTRs hade some pretty good runout but it's not noticeable at all, or at least not noticeable up to 80 MPH which is about as fast as I've ever taken it.

With my MT/R I've had no issues on road noise. They are still somewhat new (since last November), and have not had any issues what so ever. I got my tires at Discount Tire at a good price with rebate.

Have you considered filling them with airsoft bb's Not a lot, just a few ounces. I bought a 2,000 count jar of air soft bb's and split it between 4 tires. I have not had a problem with tire balance. It sounds hookie, but it does work.

For years I used a tennis ball in each tire on my semi. Everytime I bought new tires or broke them down for a repair I tossed in a new tennis ball. Does sound hookie but, your right it does work.

Look at centramatics, all they are is a ball bearing in a tube track doing pretty much the same thing a tennis ball would do inside a tire. I have freinds that use these on their trucks.

look at this thread, http://www.jeepsunlimited.com/forums...d.php?t=467662

I've haven't any issues with my MT/R and they are 33x12.50. So they are out there, just not sure where you'd have to go. I went to Discount for mine, and they balanced them
