Wheel compatability

Looking to upgrade 18 inch wheels on 2002 c2 to 2004 gt3 rims. Is this a good idea?

Rear vs Front Tire Size

How big can I go on my rear tires without causing traction problems on the front. Today I have 275 / 35 / ZR18 on back Michelin Pilot Super Sports and 225/40/ZR18 Falken on front. Bummed the new rear tires wore out fast 18 months compared to front used over 3 years. I'm told that big on back can create front oversteer. So what should I do to optimize balance, treadwear and traction yet still have fun taking fast hard turns freeway or racetrack?

tire service in Corpus Christi, TX

I need a reccomendation for a tire shop in Corpus Christi. I need a valve stem replaced. Any shops that I should go to? Thanks

Are external valve stem based Tire Pressure Monitoring Systems safe at speed?

I installed a set of Michelin PS-2 tires about 3 months and 3,000 miles ago.  Since then I have experienced 2 road hazard events which resulted in ruining the rear tires.  My thinking is that if I had real time pressure monitoring, I may have been able to stop the car before the tire's destruction.  My car did not come with a Tire Pressure Monitoring System.

Symmetrical wheel spacers for 996 C4

I have stock rims on a 2001 C4 with 225/40/ZR18 fr, 285/30/ZR18 rear Continentals.

I've read a several threads regarding wheel spacers with various widths, but I have a simple question: wouldn't it be best to do the same width (e.g. 15mm) both front and rear to maintain the same balance/handling characteristics Porsche intended? I've seen where it's been recommended to do "at least do 7mm in front to address the understeer" if someone is widening the rears, so I'm assuming doing a symmetrical change f/r would eliminate any alteration of that balance?

will 245 35 19 front 315 25 19 rear tires fit on 19 inch porsche rims

will 245 35 19   front and  315 25  19  rear   tires fit on porsche 19 inch rims ok...for 2003 911 turbo...


I replaced the rear tires with Pirelli P-O 285/30ZR18 about two years ago . The center of the tires in the rear only are badly worn . I never knew about summer & winter tires until I started looking for replacement tires . The front tires are fine . Any suggestions on replacing all 4 tires or just replace the rear tires ? I dont usually drive the car often in the winter but am I damaging the summer tires if I use them in the winter ? I put about three thousand miles a year on the car and mostly in the warm weather .
