I replaced the stock Goodyear Wrangler ST's (235/75/16) with these Wrangler RT/S's (255/70/16).I am very pleased with the smoother handling as well as the sport look the wider and "taller" RT/s's give.The main differences that I have noticed are,much better performance(traction and steering) and just a little more "road noise".The first really outweighs the latter.Overall great tire.
My Ford 150 came with Wranglers in '98, I bought one a couple years ago and paired it with the unused spare, but the other two are the original tires, 60,000 miles on them. They lose a little air in cold weather, probably through the valve stem. I'll buy two this year and I should be "Good to go" for a while!
