Sure. The sidewall of the tire would blow out from hitting a pothole or other road hazard. This is a very common issue on 21s (Tesla makes you acknowledge an increased risk of blowouts, when you buy the wheels). The issue is more prevalent on Teslas because they are extremely heavy cars. I am a careful driver with a light foot. We are not talking about absent mindedly driving through a crater and excessive speed. Two out of three blowouts were caused when driving across the lip between asphalt/subsurface, left behind because a roadwork crew was doing multi-day work. None of these were covered by warranty, and required a new tire at my expense. The roadside assistance experience varied. One time, Tesla Roadside Assistance was able to dispatch a local repair person with a spare wheel/tire set. They arrived within 5 hours, swapped wheels on the side of the road, so that I could continue driving the car, and then a few days later brought me back my wheel with a new tire, and swapped out the loaner wheel/tire. The loaner wheel is painted bright red to discourage borrowers from "keeping" it. I did not pay for the assistance, but did pay for the new tire. One time, Tesla Roadside Assistance did not have any spare wheels nearby (apparently Tesla is winding this program down). So they dispatched a tow truck. The tow truck arrived within an hour ish and towed my car to the nearest Tesla store, where the tire was replaced. I had to pickup the car a few days later. I did not pay for the tow, but did pay for the Lyft back to my house and the new tire. One time, I was close enough to home that I just pulled over and parked the car and walked home. I did not call Tesla Roadside Assistance, and instead booked a mobile service. This was the last straw for me, so mobile service took the 21s off the car and put 19s on the car. I had the 19s, so did not have to pay for them. But I did pay for the new 21 tire (I wanted all 4 tires to be working so that I could sell the wheels) and Tesla charged me for the service.
