I have the Ecsta STXs in 305/45s on my truck...they had excellent reviews on Tire Rack from actual owners, and I got a great deal on them. They're great on dry pavement, wet pavement I have no idea...I don't drive the truck in the rain. I know, :crazy: , but it's such a PITA to wash it after you drive it in the rain...I just drive the beater instead. I only have about 500 miles on them since I got them in April, so I don't have any treadwear input. One of my buddies had the 420s on his Lightning and they were a kick-ass tire. I don't think you can go wrong with any of those 3, just see what you can get the best deal on. And like Dalton said, stay away from the Goodyear Eagle GTIIs, another friend has those in 275/55s on SS 20's on his Z71 and he has to use Autotrac in the rain if he doesn't want to be all over the road. It's almost like all Goodyear street tires look half worn even when they're new...we bought the wife a new '07 Impala LTZ and the stock Goodyears looked like they needed to be replaced right off the lot.
