Uhhh. I have never seen a run flat tire have a claim to be driven at speeds of 65mph when damaged or low on pressure.

I've sold my run flats (really easy). If I were you and you're planning on going normal tires, just get them now and sell your 3 good run flats.

Also, the shops telling you that you need a special machine to change a run flat tire are just lying to you. They don't want to deal with it is all, it can be done on a decent tire machine. They're lazy.

I wouldn't trust a bulge in my sidewall, nor a showing belt. That's just asking for trouble, and the front tire is the one you don't want trouble with. It's not an "IF" question, but a "when" the sidewall will give out. Probably going around a corner. Probably at 55.
