Balancing Big Tires
Well, not that they are the biggest out there, but Town Fair Tire went 0-2 trying to balance my 37x11.5R20 Ridge Grapplers. They added 8oz of beads per tire which reduced the vibration, but it's still there, and quite irritating. There isn't a lot of big-tire/offroad places around up here.
Those of you running the bigger tires... similar issues? I'm not sure if I should just take it to Ford and have them Road-Force Balance them, add 4-6oz more beads, or what. Was also debating trying to add Centramatics as well.

I have alsohave a set of 37x12.5r17 Delium terra raider AT. I mounted them at my buddy's shop and took pics of the Hunter machine as I went and marked/numbered the wheels so I would know what each tire needs for weight and where. I do need to add some stick on weights as some of the tires need 8-9 oz of weight. It isn't terrible and only comes noticeable on the highway. With that said I have taken multiple trips to my brother's in ME from CT and still haven't done anything yet. I'm not as bothered by little things though as much as some, so keep that in mind with my opinion. They are worth a shot for the money I think, and leave the balance beads in.

I have 315/70/17 Ridge Grapplers on my Dually and cannot get rid of the vibration.
They have been on for 10k miles since the truck was brand new. I have had them balanced with weights, tried beads, removed beads, tried centramatics with no weights, balanced with weights again with centramatics. Still that vibration above 70mph. Passenger seat shakes if no one is sitting in it.
Cannot have them road force balanced because of my particular size tire on a dually wheel cannot be done by anyone in my area.
The vibration feels more like in the rear half of the truck. Never in the front end. Even when swapping/rotating tires around. I'm starting to wonder if its driveline related. Or maybe just a lightweight aluminum truck with load range E tires under the back end with zero give.

I run beads in all my trucks, 35's are the biggest, the thing with beads is you should have X oz. of beads depending on tire weight.. I forget the X amount, but I think it's 1oz. per 10lbs... I could be wrong so don't take it for fact, I would look up the weight of your tire and then adjust accordingly. I'm thinking about swapping to them in my F550, as with the traditional weights they are terrible.

I have had this problem with smaller tires in the past, 33's. Purchased from discount tire and re- balanced multiple times (not with beads), including road force balanced. It never completely went away, only changed the intensity or speed at which the vibration could be felt. I suspect in some cases it could be a bad tire. In my case Discount tire claimed they were all good.

I don’t consider 37s to be “big” but I have some Kumho at52s in 37x12.5 mounted on weld off-road 20x10s and they did the standard metal weights to balance.
No vibration issues to speak of. If I ever did have an issue I’d probably run centramatics to try to fix it.
I feel like there shouldn’t be an issue to balance tires up to 37s.

One thing I have found on stubborn balancing is just about all tires flat spot from sitting. High perf and low profile tires are by far worse, but you can try driving on the highway
for a long period. Get the tires nice and hot (and hopefully as "round" as they are going to be), then take all the wheels/tires off as soon as you get home,
and transport them to your favorite balancer place.
I have 11 vehicles and have had my own tire machine and hunter balancer for close to 25 years. I send back about 1 in 15-20 tires that either takes way too much weight
and/or is visibly out of round, seen right on the spin balancer. I bought a "cheaper" brand alum trailer that I needed 8 wheels and tires (chinese crap) to get 4 good one's,
so sometimes the absolute cheapest tire is not the way to go, just due to uniformity (or lack thereof) of the tires brand new.

Well went to an "Truck" shop yesterday, they specialize in off road bro-dozers and they claimed to have the machines for big tires. 2 Attempts and they couldn't do it. So at this point I suspect I have one or more bad tires, and have contacted the original seller to replace them, which they agreed to do. So hopefully this will fix my issues.

Well the replacement tires finally came in last week, so got the replacement set installed yesterday. Vibration is gone, smooth as silk now. Kinda mad I had to waste so much time and fuel on them, but glad they made it right. Gonna install Centramatics this weekend, too.

Glad to hear that. I had a set of mickey thompson mtz's on my 99. Ever since new they always had a vibration, but I just assumed "Oh they're mud terrains so they're never gonna be smooth"
I made it to about 3,000 miles on those tires and then had 2 of them blow out on the same trip within 20-30 miles of each other
I now have ridge grapplers and have no complaints
