Well, I had to send my 37" back to Dick Cepek.
Started to get a bad shimmy that got worse.
Got to the point I couldn't go over 35 MPH.
Found out I broke the belts.
Gave me a refund since there was only 4/32" of tread worn off.
Don't know if it was caused by 4WD launches drag racing or what.
Know of some shops that quit handling them due to this same problem.
Went with 38. 5" Pro Comp Extreme AT's.
So far, so good.
These are all made by Cooper.
Pretty scary knowing I was going over 100 MPH with broken belts.
