I'm looking for a new set of tires for my Marauder. It's a Marty tuned Trilogy car, and the stock tire size with mid-range all seasons kind of sucks for traction in the back. I'm looking for better tires, with as much width as I can get away with in the rear.

It's an 04 with traction control, so I'm trying to keep the front/rear differential. There are not a hell of a lot of options, but I've currently put together two plans:

1) Bridgestone Potenza Sport. 275/45R18 for the rear, 235/45R18 for the front.
This should work on stock wheels (probably at the limit for the rear width), but they're about 3% shorter than stock. Maybe the slight gearing change there will be a benefit though.

2) Michelin Pilot Sport 4S. 295/45R18 for the rear, 235/50R18 for the front.
The Pilot Sports are the better tire, but I don't feel confident in that size working with stock wheels.

Any input or other suggestions?? Has anyone had success with a 295 tire on stock wheels? Does anyone want to sell me a set of widened rear wheels?
