Whats the sellers name? Thank you for the info in advanceJust an FYI. A seller on ebay is selling sets of 4 tires Pirelli that fits the RS model 265/45/21 for like $600 delivered. I have bought from this seller before and had great experiences. I might pull the trigger and get them. I have been strongly considering getting a Yukon AT4 but they are impossible to find. It sucks having to buy new tires at 17k miles.
