I have an 04' GXP with 54K miles. I purchased the car at 33K miles. It'* still wearing its original Goodyear RSA'* and I still have about half the tread life left. The key is to make sure you rotate your tires every 8K to 10K miles and don't over inflate them. I'm not real hard on the tires, but I do enjoy the V8 power plenty of times. My biggest complaint with the tire is that it doesn't bite well on drive pavement with hard take offs. I get what I would call decent traction in the rain and in the snow (I live near Kansas City, MO). I could probably squeeze another winter out of them, but I plan to replace them this fall. I have minimum vibration from one of the four tires (due to wear I'm sure), but all in all, I'm surprised with the performance and logevity I've gotten from the OEM tire. I'd like to replace them with either the Michelin Pilot Sport A/* or the Continental Extreme Contact DWS, but both of these tires are pretty pricey. Depending on funds, I may go back to the Goodyear RSA'*. That'* the only thing they have going for them in my opinion. I purchased some Goodyear Triple Tread tires a couple of years ago and had a lot of "out of round" problems with the tires. Goodyear wouldn't stand behind their warranty, blamed the car, the alignment, etc. (which was all fine before the tires were put on the car). I vowed to never buy another GY tire again.
