I've got 16" wheels, 8" and 9" wide, front and rear respectively.
I'm planning on going with 225/50ZR16 for the front wheels.
On the rears.. I'm not so sure. Should I go with 245/45ZR16 or 255/50ZR16?
The 255 is .8" wider (according to the link below), but its also 1.4" bigger diameter than the 245 (due to the larger sidewalls).
If I go 245 for the rear, the fronts and rears will have approximately the same diameter.
Thoughts on pros/cons of the 245/45 vs 255/50 tires?

Go with 245's up front on the 8's and 255's on the rears with the 9's. I have used just about every combo available and I would go smaller than 245's all around. Our cars may be well balance but the like to push and having the extra meat up front helps. I used 255x17 and 275x17 on 8.5" and 10" x 17 wheels last year which worked out very well.

ivai - I was faced with the same options,
I found two types of tires - pure street low performers and race.
To complicate matters I wanted a track tire that was treaded deep enough for rain use.
Found only one - Hankook rs212.
be sure to buy a trie for your use. After extensive research I found nearly every available tire in my size 245/45 was a severe performance compromise or race only.
have no high expectation for mileage, but that is the only drawback I identified

255/50 will affect your gearing, already pretty high in a stock 951, and they are going to change the balance of the car as well, you don't want the *** up in the air.Don't know if your concerned about your speedo reading either.

Yep, to echo the last couple posts - go 245/45s on both the front 8s and rear 9s. A 255/50 is too tall a tire for the Turbo gearing. Any slight advantage of having another 10mm tire width is more than offset by the decrease in acceleration due to the larger tire diameter (adversely affecting the final drive gearing).
