I've got a 2007 new body style silverado Z71 that came stock with Bridgestone Duelers A/T 265/65-18. I've been unhappy with them since day one. They are cupping pretty bad on the inside tread pads. I've streched them to 40k miles by relentlessly rotating the tires, but even that is no longer working so it's time to replace them. Problem is there are not many options available in that size tire, which is really hard to beleive. I want to stay with the stock tire size. I don't really want to put another set of Bridgestones on so about the only other option seems to be the Goodyear Wranger Silent Armor. The Goodyear looks like a pretty nice tire. I was also told that Michelin would soon be coming out with the LTX A/T2 in that tire size, but who knows when "soon" is. So my question is: What are you guy putting on your newer Z71's for tires????
