I have, what I think, is a slightly unusual tire question. I have a Silverado 1500 (Crew Cab, 4wd, LTZ, Z71) and need to replace the tires. This summer we are planning on going on a grand "Out West"...
A sidewall cut is more a concern than traction. Firestone AT get great reviews and are priced right usually. I've used them and was satisfied. Made it to the top of Engineer pass with a set of those in 2wd.
