Long story short the current tires were originally on Avant Garde M550 wheels I had a ton of problems with. So I pulled the tires off, and got TSW Bathurst wheels instead - which are fantastic.

Currently Running:

Front: 19 x 8.5 +15
255/35 ContiExtremeDW

Rear: 19 x 10.5 +27
305/30 ContiExtremeDW

I'm looking at either RE-11 or new PS4S in same sizes, or going to 245/40 front and 285/35 rear.

Car is my DD, and is NA (so know the 305 in the rear is probably slowing me down a bit).

Any thoughts & input would be most appreciated.
