The front passenger side run flat that my car came with blew out with a small tear in the sidewall today. The tires only have about 17000 miles on them. In a spot where it feels wasteful to buy one brand new one as the tread difference would be about double on the current tires. Thought about just buying a used run-flat for the time being. Thoughts? Thanks.

Definitely better to get 2 new ones. They normally only last 20k miles anyways. How much tread is actually left on the other front?

Sell your one tire and buy two new.

Or take this as an opportunity to get 4 new non-runflat tires

This would be my advice as well. Better to have a matching set, especially on the front.

Definitely get two. That has happened to
me a few times after taking a few construction nails in the tires.

There are some new Michelin Pilot sport 4zp run flats that seem at least to me worlds better than anything I have run in the past. In case it matters they are also star bmw rated.

I have also noted that the tire pressure on the door does not work well with oem run flats. My dealer recommend different pressure and on my second set of tires I doubled the mileage on them. The door says 32/35 for my 340. The dealer said 36 square and that has worked great. I would probably even go to 36/37 as the backs wore just a slight bit faster. For me, the first set of rfts were all worn on the edges, not the middle using the 32/35 setting; with the 36 square I had even wear on all four tires for the most part (maybe a little bit more on the back. I have a staggered set up so I can not switch from front to back. Anyway I hope that might help?

Best way to go may be to replace both tires w New

Hey everyone appreciate everyone's input. I know some time has passed but wanted to give a little update. At the moment when I had made the post I needed to be able to drive the car asap since I had a family member in the hospital. All local shops did not have tires in stock and needed to have them shipped which would have taken too much time given my situation. I went ahead and just replaced the front with a used run flat. I have bought a new set of tires and am going to be replacing all 4 of them soon enough
