I run 33x12.5 Kelvars on my Bronco out it Arizona, and have had them for just over a year. Excellent tire for offroad. I run about 15 psi on rock, and they take the abuse. I am extremely happy with the tire. I used to run a cheap AT tire, and in one week I cut 3 tire sidewalls on rock while offroad. So far the only thing that has bothered my MTRs is a nail I picked up driving back to AZ from Vegas.
I would not buy them if you are mostly on road. Also, if you do not like white letters, make sure you order them without. You will not be able to put the white letters on the inside as the tire has an asymmetric tread, so it specifies an outside and inside sidewall.
199 a tire is a great price for those. May I ask who is selling them at that price?
