Curious if anyone has observations on long running Roadsters. I just hit 10,000 miles in 7 months of ownership. Does anything special happen at higher mileage levels? Love it and the the Tesla crew out of LA. I'm still running on the factory set of rear tires that are supposed to decompose/wear out at 5K. Am I doing something wrong? I'm in Las Vegas and the car is primarily on freeways and rarely on mountains.
