What the heck are you driving that takes 305's in the rear?
I have 275's, and that is considered very wide...
A 911?
That is on my 997 Turbo S with engine upgrade. My older 1977 rally 3.3L 911 RSR now has to fit either Michelin TB15 23/62 x 15" or Pirelli P Zero Corsa Classico 285/40 x 15" on the back, as nobody now makes ordinary road tires in the correct 275/45 x 15" size. These road legal race tyres arrive with only around 4.5mm of tread on them (pre-worn). I did the Scottish Malts trial last year and even though we trailered up and down, we still wore a set of the Michelins out in 5 days/1200 miles.
