Nope, I use the Cooper Disco S/T tires. This will be my third set, first two were on an S-10 ZR2 (31x10.50's). I got 45k and 50k out of those first two sets. I've put about 5k on these new ones (35x12.50-17's) and they look like brand new, which they should. Anxious to see how well these hold up on a larger, heavier truck.
I have had great luck with other cooper tires that I've owned as well.
