So I understand that most BMW’s leave the dealer lots with run flat tires. I need to replace my tires soon and was wondering if it was necessary and mandatory to replace my worn out tires with new run flats or can I go with regular non run flat tires? If so, what are the pros and cons of run flats versus regular non run flats besides being able to drive on a flat tire for x amount of miles? Thanks everyone!

You can switch to non run flats. Your car doesn't have a jack or spare tire though so if you get a flat you're stuck using a fix a flat kit or calling roadside assistance.

Non run flats are less expensive, come in more sizes, have more options of brand, ride more comfortably, often make less noise, and are generally preferred.

Went from runflat 225/45-18 to summer Michelin Pilot Sport 4S in 245/40-18. Makes runflats seem like old wooden wagon wheels. In San Diego weather you can run these awesome tires all year round. Amazing on dry and on wet roads. Get a Slime 8-minute kit at Walmart $45. Harbor Freight has scissor jack, breaker bar & 17mm socket. See attached photo.

The only thing I know of is that if you are leasing, and the car came equipped with RFT's, when/ if you return it at lease end it must be returned with. RFT's. As far as any warranty issues are concerned, I do not know how non RFT's will impact that, mbut if the stealership can find a way to deny a claim I'm sure they will jump on it. Such as: any warranty issue with suspension, brakes, steering the stealership will most probably try to blame the use of non-RFT's; but I do not see how they could use the non-RFT issue on things like defects in leather, defects in sound system, etc.
