38x15.50x16.5" Swamper Radial TSL

[Tinzman8]

Hey guys, i just bought some brand new 38x15.50 Radial Tsl's from a guy on craigslist. I got them mounted/balanced on some 16.5x12 Rock Crawler wheels at les schwab. I drove for the first time and i cant get above 35 mph before the truck starts shaking. I took it back and they checked the balance again and added a little weight to them. It made it worse, now i can only go 30 mph before this happens. Any advice? Anyone had this happen? The truck drove great on my toyos before i got these.

check to see if the tires are out of round, example: you can balance a pencil on your finger but it doesnt roll well, I have the same problem with a set of bfg's that were smooth for the 1st 30k and next thing I know is it bouncing everywhere

My experience with swampers is they shake real bad at certain speeds, have you tried powering past the shake?

I agree with ^^^ see if you can find a place to true them up for ya.

if they are out of round and they are nearly new you can have them shaved or trued and then rebalance and be good to go, bad part is you lose alot of tread while shaving them. My guess is if you got a really good deal on them the seller probably already knew the problem.

I agree with bwmntbiker.. the thornbirds I had several years ago rode like pure crap at certain speeds. Once you went over or under those speeds the smoothed out and rode nice considering the tires.

Yeah round 50 or so was probably the best ride I got with them. The TSLs I had were bada** in the mud though had them on two different broncos.
