I bought my 2016 535i a few minths ago. The car has factory warranty 20” wheels. Came that way, they ate on the original window sticker. It has Dunlop runflat BMW spec tires on 3 wheel and drivers front is a generic WalMart radial. Its got a vibration from the front and the dealer said its because the passenger front runflat has a bulge in the sidewall. So i am talking to them about the options, they said they may split the cost on a new tire. But now i notice the non runflat on the drivers side, and reading how they shouldnt mix tire types on the same axle for safety. Should they be replacing both tires? Just wanted some opinions before I addressed it.

Different tire brand may have different thickness even though it’s the same tire size so it is recommended to have matching tires. Get rid of RFT all together if you can. They are bumpy.

So if I ditch the runflat tires, what is everyone doing to be comfortable driving around without a spare? Is there a space saver spare that I can get that fits in the trunk? Or do people just flatbed it if they get a flat tire? Tire sealant and cross your fingers?

When I gave up on run-flats, I bought a plug kit and a sealant kit. It doesn't take up space and is practical in most cases. Although if you get a bigger cut, then they are of no help.

Knock on wood but I got rid of my run flats in 2018 and it was the greatest decision I made

I bought a bimmer space saver tire had that for a couple of years in the trunk but it was taking up too much space

I have a tire pump now so anytime I’ve gotten a flat I’ve been able to put air in and make it to discount tire but if I ever get a flat where I can’t make it somehere to fix I’ll just call triple A

I also just keep a plug kit and small compressor in my trunk.
