I run staggered 245/40/18 front as 275/40/18 deep rear. Totally transforms the stance and overall look of the car. Looks amazing IMO.

Those sizes (255 and 275) on an 8 inch wheel will make the car feel "squishy," and will compromise handling to the extent of being dangerous. The rule of thumb is to mount low-profile tires on wheels that are at least 80-90% of the tire cross-section.

However, a 245 tire can be mounted on an 8 in wheel. It'll give you about 0.4 in more tread. May not be noticeable to the average eye.

Tradeoff: 245/45-17 vs 235/45-17 (OEM size). Slightly wider tread but slightly taller stance. The taller sidewall, in general, should improve ride quality while reducing cornering and possibly steering feel. This small difference may or may not be noticeable, either in performance or appearance.

I was happy with my Pirelli P6's (235/45) but they don't make em' anymore...

My Wrench recommended the Conti DWS... There is a $50 difference in price between the 235's and the 245's... I beginning to think it won't be worth the trouble or the money...

I have the Conti DWS. Very good but not great. I had Pirelli P Zero Nero A/S previously. These were better (ride & quieter). Both handle really well. Just something to consider.

OK, I have the 235/45 DWS's installed now... After 20 miles they seem just fine to me...

I forgot to mention my wheels are 8" in the front (on 245 tires) and are 9" in the back (on 275 tires).
