In the 6 months I had my smart, I got 2 nails in tires. First time the tire wouldn't hold air. Fortunately, I was close to home and friends -- one came, we took the wheel off, and I took it to Discount Tire, where they repaired the tire FOR FREE! Four months later, I discovered a nail in a front tire, but it wasn't losing air. Drove to Discount Tire, where they again fixed it for free.
I can't say enough good things about Discount Tire. I have always bought tires there, and even bought their road hazard tire warranty on the tires on my other cars shortly after I bought the cars, for just in case. They have twice replaced damaged tires under the warranty. Once I was on a road trip hundreds of miles from any of their locations, and they repaid me for the Goodyear tire I had to buy.
I hadn't yet gotten their road hazard tire warranty on the smart before I decided to sell it. But I would recommend it to anyone. The warranty is transferable with the car, too. I think for my last MINI the warranty was about $80 for the four tires (which of course came with the new car).
Just my $0.02.
