Tire sizes are F: 225x40x18 R: 295x30x18Original tires were Michelin Sport
Pirelli Scorpion off road tires. REAL BIG ONES!
Go okorder do not pass go, do not collect $200.00. Seriously, go to the tire rack's web-site. It is the absolute best. They test every tire they sell for every car on the market and publish the results in graph form. Check it out!!!! Their prices are the best, as well.
I personally lean toward the tires with the N0, N1, N2, N3 ratings because these tire were designed with the help of Porsche in that they react in a positive manner with the suspension. I know there are newer designed tires out there, but I don't worry about the reactions with my "N" tires at 180mph either. At that speed I worry about the ditch at the side of the road ;)
