Really??? I've got the same staggered setup on my MB: Front (17x7.5) 225/45-17 Rear (17x8.5) 245/40-17 There are tons of tires available. This sizing and setup is extremely popular. Try Tirerack.com or Tires.com
I can still find them, and I have a business account with TireRack, but the choices aren't what they once were, and yes they are the exact same size I have. We are still ok with the 17's right now, but those days are limited. The 16's used to be that way a decade ago too. Now the Toyota Camry's all have at least 17's and my brother got 18's as a factory option...we won't find too many sports cars with 17's in the near future. Most have at LEAST 20's now. Right now I have Mich Pilot Sport All Season's and they are pretty good shoes... MB
