Can some please confirm the correct tyre size for a 1991 turbo

I'm guessing 225/50/r16 front. 245/45/r16 rear. 7.5" fronts 9" rears

I'm someone could confirm this was factory fitment

Cheers Ken

Your tyre sizes match what was specified in 1988.
However in 1990 front wheel width was increased from 7J to 7.5J.

Previous turbo's could have 205/55 VR16 front 225/50 VR16 rear.

The source of my info is Haynes Porsche 924/944 book.

250PS cars had 225/50/16 fronts and 245/45/16 rears, irrespective of front rim size.

Better book needed...
