I just got my new Kevlars installed. The manager proceeded to lecture me on the use of my tires,saying it was obvious that the sidewalls had contacted rocks and other sharp surfaces...duh!!! I told him, "no ****, thats what those tires and my truck were made for". He was not amused, he seemed disappointed that Goodyear offered to replace my tires for free, I didn't pay a single dime. They did not wear well either, 1/8" off of the front an 1/16" off the rear in less than 2K miles. I also managed to tear off a few of the outer lugs. They handle awesome, and are very quiet, and are killer in mud and on rocks. But based on wear and cosmetic issues, i would not buy these again. The new tires are slightly different, so hopefully Goodyear fixed their QA problems on the cosmetic black coating and the softness of the rubber. I will post up in a few months if they do the same thing as my first set.
On the RS I am putting some Swamper TSL Bias Ply tires. Those things are indestructible and much cheaper than the Kevlars. I could buy 5 for less than I bought 4 Kevlars.
