Tyer size ?

[SLR]

I know it is here some where but do you think I
can find it .
I want to fit 16X9" rims on 85 911 at the rear and 16X7 on the front
with the rear's am I right that 265 X 40 work?

Waiting for the caining Steve,

[Oh Haha]

265/40/16 will work great on a 9 inch wheel. That size is not available from many manufacturers, however.

Depending on how low the car is you MAY have to adjust the height or roll the fender lips.
