Does these tires fit the turbo wheel on a cayenne:

275/40/20 106Y XL Fronts
315/35/20 110Y XL Rears

 

Just guessing but doubtful. 315mm is over 12" wide. I think the stock rims are 9 or 9.5".

 

Would 295 fit?..I think I saw 8..9 or 9.5 would be nice

 

I would go with stock size on stock wheels. The tires are wide enough already and has great traction. Not to mention these arent super cars that require that amount of contact with the road. Plus I wouldnt run a stagarded setup since this is AWD, just thinking about it gives me chills.

 

Can be done, only on the OEM Sport Techno(CTTS) wheels. Honestly, you don't need 315mm in the rears...

 

There are two different sets of factory Sport Technos. Mine are 20x9 all the way around. The Sport Technos for the CTTS are 20x9 in the front and 20x10 in the rear.
