First off, I'm a first time poster. I apologize if this question has been asked before. I recently bought a 2003 RS6 to replace a 1999 Porsche 911 that I recently sold. We have a 11 month old and wanted a sports car that would accomodate a child seat. The RS6 has definitely fit the bill.

Here's the question I have. Yesterday while driving I hit a shallow pothole at about 40 mph. This caused a bulge on the sidewall of the tire. I have to replace the tire, but the local tire place is telling me that I can't just replace the two front tires, and I should replace all four at once. They are telling me that it could harm theall wheel drive systemif the front tires tread does not match the rear. Is this true or are they trying to sell me more tires? Thanks in advance and I look forward to participating in the forum!

All you need is a tire to replace the damaged one that is the same as the other three. If the replacement is not the same exact tire it is nottoo good for the car, but someonecould argue it really isn't that bad for temporary driving.

Depending on how much tred is currently on the other three you could just get a whole new set if they are low. If not, just get a replacement, but make sure it is the same tire as the other three.

Hope that helps
