My E500 just arrived. One item I plan to get for the car is winter tires. We live in DC, but it usually snows enough to be a problem, and last year was particularly bad. My wife, who has an E430 with Michelin Pilot Sports, had a terrible time in snow. So I will get her winter tires, as well. Anyhow, it occurred to me that since I would be getting new wheels (so I can change the tires), I could get the new wheels for summer tires, and use the factory wheels for the snow tires. Having looked at the Tirerack site, I am thinking of RRS CH 17x8.5 wheels because I liked the look of them and they are the same size as the factory wheels. I am thinking of Michelin Pilot Sport A/Ss as the "summer" tire; from Michelin's website, they perform almost as well as the Pilot Sports in dry conditions, perform better in wet conditions, and have better ride and noise characteristics. I would appreciate Luke's thoughts as well as anyone else with suggestions.
