These seem to be a great new tire and they recently came out with a more closely matching front tire size. However, the front tire size is not exactly OEM size and is about 1" less in overall diameter. The OEM Pzero is a 255/40-20

255/35ZR -20 Michelin Pilot Super Sport
295/35ZR -20 Michelin Pilot Super Sport Ferrari

Do you think this will cause any errors with the computer systems?

Either way I ordered a set and will let you know how it goes and if I can break into the 10s.

 

 

Falb, as long as you do not go over 3% size the 4WD drive system wont have a problem. You could go to 1010tires.com and adjust and tinker with the sizes to find out whats up.

Have fun, keeping in mind that anything close to 3% will give you headaches with the car.

Good Luck!

 

Well it is more than 3%. Anyone have personal experience with this?
