Guys , I would like your suggestions on a good tire for my chevy silverado z71 extended cab. I tow a bass boat and 6000 lb camper and mild very occasional off road , boat ramps etc.I want one with a good ride and as least road noise as possible , but like an AT tire. I had BF Goodrich AT KO on my 99 z71 reg cab that did the above very well , but beat me to death as far as ride went , they were E rated though. Thanks for any suggestions.The truck is a 2007 , 5.3 engine , and 270 65 17 size tires.
