Tires and Spacers Again


Recommended Posts

I recently got my first Porsche 2003 C2 Cab. It came with the stock 5-star Carrera wheels with 225/40/18 on the front and 285/30/18 on the back. The dealer I bought it from put 15mm spacers on all 4 wheels and they are nice and flush with the body.

However, being a nut about big tires I would like to put 295/30/18 on the same rim on the back and 245 on the front (my MB SL had a 285 on a 9.5" rim so I figured that a 295 should fit on a 10"). I am a rather conservative driver so looks is more important then performance.

I searched the forum for anything about tires and spaces and found several references from Loren about putting 245 on the front.

So here are my questions:

1) Could I put the 295/30/18 on my current 10" rim? I would/should probably change the spacers on the back to a 7mm after the tire is about 5mm wider on each side. I don't want it to stick out of the fender.

2) What 245 would I need on the front? Would that be a 245/35/18? Based on Loren's comments they should fit on my 8" rim. But what about the spacers on the front? I assume I would have to either remove my 15mm spacer altogether or change it to a 7mm or even a 5mm?

Thanks for your comments and feedback.

I think tire rack or one of those will tell you what sizes fit on which rims. And unless you absolutely don't want to turn a wrench yourself, just answer your own spacer questions after you put the tires on the wheels. Spacers are by definition super easy to add and subtract. When the wheels are on the car, you will know what to do.
