Thought I share with the group my recent experience with a flat tire. Inevitably I got one on the ever-so-pristine freeways of Southern California (405 and 5 split precisely) - a bolt the size of a small child went through the tire deflating it in about 30 seconds I had to pull over. Called roadside, waited about an hour for the spare wheel to arrive and was in my way. The interesting part was when I called Tesla Service Center to check and schedule an appointment for the swap. I was quoted $425 for the stock Continental 20” tires. I decided to shop around and called America’s Discount Tire, CostCo and a few other places - the best price I got was $275. I though I was going to have to buy it outright and then get it mounted by Tesla, but when I called, they said they’d price match. Asked to see a quote - easy enough. When picking up the car they didn’t even confirm or verify - just trusted me on the price I told them and honored it. So...I guess it helps to shop around and do due diligence before accepting the Tesla inflated pricing at the service center. Go out there and haggle!!
