I have the 35x12.5xR17's and I hate them all around. The sidewalls are thin, they are soft, they are horrible in the rain and snow. I replaced my Dick Cepek Mud Country's with these. What a mistake, I will never buy these tires again.
Again this is my two cents, my next tire will either be the Nitto Mud Grapplers, Toyo's or Dick Cepek's again.
I have put about 20k on mine, also will driving I can feel the tires (I don't know how to explain it but) flex on the road because the rubber is soft. I am running 30 psi in them.
