A year or so ago, I installed a brand new set of 35" MTR's, and they have never balanced correctly.
Bought them from 4wd Hardware. After they shipped, I took them into a well know local tire chain for mounting and balancing.
They used a road force machine that helps get the tire matched to the wheel as close as possible weight wise, before adding static weights.
Tech says he can't get them balanced at all. Said he got them as close as he can, and 2 are worse then the others. We put the worse on the back of the rig.
Test ride it, and no way, nuh uh, na ga do it. So thinking is the wheels are bad, as the last set didn't balance well either. I get a new set of wheels a couple weeks before a cross country trip to Moab. They swap them out, and still had the same issue. We threw in 8 oz of Dynabeads in each tire, and had to call it good, as I ran out of time. Rig was on a trailer for this trip, and this didn't matter for the trails out there.
Fast forward a year.....
Another trip to CO is coming up, and these tires start to shake at 60 mph. these won't work, as this time, I'm not using a trailer. 2 days travel one way at 75 mph. Had to take them off, and run a set of BFG AT's that are balanced well.
I decided this isn't going to work with these expensive tires that ride like crap on the HWY, at speed. So I hear all the talk about the tire size and wheel size, and how it is common place for this to happen. Well, I don't accept that one bit. I have ran other tires the same size and no issues. I just came back from a 2000 mile trip on the same size with no issues.
I find out after some research, that when this has happened to others with these MTR's, they had luck with Goodyear service. They kept on sending tires, until they balanced. I have a 6 year full replacement warranty on these. They prorate after 1 yr, but it is minimal. I have about 1000 miles on these tires, and they look brand new still.
I contact Goodyear, and they send me a file #. Then instruct me to take it to an authorized Goodyear dealer. As luck would have it, the original installer is not. I find a shop, make an apt, and bring the rig in. They tell me they can't get to it yet, and it will be a long wait. Then tell me they want $35/ea to even look at them. WTF? So I ask why. They said they have to remove the beads first, then test them on the balance machine. I tell them I will handle it, and bring the tires back loose.
I had the original shop remove the beads for $40, drop the loose wheels off at the dealer. 2 days go by, and I call them. They said they got them to balance, and come pick them up. Hmm....
So I get there, and look at them. They put more static stick on weights on a wheel, then I have ever seen before. I am not happy. I take them and leave, telling them I will test them out. If they still ride bad, I will return, and expect new tires from Goodyear.
So here is what they did. (Wheels are a mess from the last couple outings)
3.75 oz
5.5 oz
7.75 oz
10.5 oz
Put the two with most weight on the back, and took it for a test ride, and it did ride fine at 70 mph. I am on the fence about this. Is that much weight alright? I feel it is too much, and just a band-aid fix.
