205/50's fit on the 7" wide wheel, 7" < $ than 8" and 1 lb. lighter. I'm not going to be Auto-X'ing that often so didn't see the need for wider wheel....IMOWhy didn't you go for 15x8?
Tirerack has great reviews on the RE-11 but they list the 205 weight as 21#, the Bridgestone site spec. has it at 24#, so the only negative on the RE-11 is it's the heaviest tire in that size, vs. Yoko ADVAN Ad-08, Falken RT615K. I didn't find out about the 24# weight until after I ordered the package...might have gone to the Falken RT615K instead. (buyers remorse?)The reviews for the re-11 look pretty good.
