Thanks gents. That's good to know about the 205/50's -- widens the choices a bit. I guess I need to look at exact manufacturer specs to determine height/diameter for a specific model of tire, which i think can vary a little even within the same published size, and then make a decision.
Cheers Ian, but there is already less than 1" clearance to the fender brackets with the 195/45 ACB10's as I had to replace the original brackets with something beefier a while back after the OEM's failed dramatically when airflow at speed almost peeled one of the fenders back and off the car! So I don't have a lot to work with when changing the profile up from 45.
Gordon--I wonder what year your car is, as it seems to have slightly different front fenders (at least mine don't have the reflectors) -- maybe yours are wider. My car is a 2002
But good tips/reminders on tire shaving for height and putting a spacer on the fenders for width.
Bruce--I'll try to take some pics soon and post them up. In florida by the way.
