I have a 2005 E55 AMG Wagon -- these are rare and may not show up in your database. I was looking to purchase the following wheel/tire combo from The Tire Rack:

19x8.5 AMG Double Spoke 2pc Bright Sil w/Mach Lip (FRONT)
19x9.5 AMG Double Spoke 2pc Bright Sil w/Mach Lip (REAR)
245/35ZR19 Continental ContiSportContact 2 Vmax Blackwall (FRONT)
275/30ZR19 Continental ContiSportContact 2 Vmax Blackwall (REAR)

I was going to try the Contis because their load rating seems more appropriate to my wagon than the PS2s. Also, the Contis seem to be one of the few tires that can handle the occasional burst of very high speed and I plan on delimiting my car. Though this would be infrequent I like to have a large margin of reserve for safety's sake (can you say "overkill").



I'm a little hesitant since the Contis are so new that there is no test data available. Do you have any additional info on these tires? One other concern is ride harshness with the decreased aspect ratio. This is a "real-world" performance car for me that is driven almost daily, and I'd like to keep the ride quality as close to stock as is possible. I realize that going to 19s would probably compromise the ride quality, and it sounds as though these tires have a stronger construction that may increase the stiffness of the sidewalls. Tire noise is also a concern since my car is driven quite a bit. I don't want to make an expensive mistake, as the package I'm looking at costs around $6,000.

I am also wondering about the increased tire width (compared to stock) in the rear. Are you 100% positive there is no chance for rubbing under normal circumstances? Also, when you mention: "Necessary wheel installation hardware included at no additional charge" what does that mean? Are spacers required with these wheels, or are they made for the car?

Thanks (in advance) for your input!
