[V8] Tire size for 17x8 rims

[quattro + 5 or 8 = fun]

i don't have much time to go out and get the details at the moment (on the
wheels), but i have 18X8.5 rims (speedlines) with 255/40/18 AND the car is
lowered with H/R, bilstein suspension.  I have a 5 MM spacer in the rear and
a 10 MM in the front.  when i have more time, i will check the ET.
