Need new tires for my '01 GMC 2500HD Duramax, it's 2wd with a locking diff.
I tow an '04 34ft Classic Limited with slideout sofa, about 14-1500lbs hitch weight, and a Hensley Arrow.
I've had issues on a few hills that were wet, a little muddy, after a recent rain, and on loose gravel hills......once on wet grass backing up a hill into a campsite. Tires were Michelin LTX M/S
Getting new tires this week, debating between Cooper Discoverer HTR and Discoverer ST/ST-C and STT........concered about excessive noise, some added noise is ok, and is certainly a good tradeoff for good traction. But I notice the ST-C and STT with the more agressive treads have less dry and wet traction?
also would going from 245/75-16 to 265/75-16 do anything for traction?
PS, unless we downsize the trailer drastically, my next truck will be 4X4
