i found a good price on oem 17inch twists that came off a boxster. i have 16 inch phonedials now - sizes 205/55fr on a 7 x 16 rim and 225/50 rear on a 8 x 16 rim.
upgraded to 17's
new rim sizes are 7 x 17 and 8.5 x 17.
what is the best set up for tire sizes on these rims ? i do mostly street/hwy drive i prob will do a few DE's.
im i really limited with the 7 x 17 up front ?
thanks

You should run 225/45 and 255/40-17s on these rims. Take a look at my web site and you'll see how they look.
