My C2 becomes a tire eater

Recommended Posts

My 99' C2 becomes a tire eater. Few months ago I changed my rear tires to Kumbo MX 18" and they only last for three month around 4000miles. Then I changed them back to P Zero and did the four wheel alignment ,now only 3000 miles they almost gone again. Both rear tires wear evenly. however, I always find my rear bumper has black particles and stink smell when park into grage, which are obvious the rear tires worn out violently.

I live in Southern California, not a aggressively driver.

Thanks for any input.

Thank you everyone, alignment done by my local grage who fixing Porsche and other Europen cars. I printed out the alignment data from this site and they using a computerize equipment to go the job. My '99 C2 has TC, which always on, if it's correct? or I better turn it off.

There's screech sound from the rear tires in slow turns only when the tire traction was low.

Any spacers or non Porsche wheels? If so how large are the spacers and what is the size and offset of the wheels?

If you have TC then you likely have a LSD. You should not get any screeching except when a rear wheel is slipping.

Hi Loren, Thanks again.

Everything are origial , I did not add/change anything. I think I'll need go to the dealer and let them to check this time. :( (or it might be the last alignment did do right.)

Yeah, something must not be right especially if they both wear fast. Cars with TC and LSD don't usually get poorer mileage out their tires unless they track the car a lot. 996's go through rears about twice as fast as the fronts but still even aggressive drivers (like me) still get 9000 - 11000 miles on the rears. I'm the guy that got 9000 ;)
