Run Flat Help

Daughter borrowed my wifes 2007 328i last night. Went i drove it this morning it felt like it had a bad tire. I checked the tires and none feel flat. Never dealt with run flats before. Is this normal? If i decide to replace with regular tires and purchas a spare and jack is there anything i should be worried about. Thanks in advance.

Just useless trunk space.

Check the sidewalls and check for bubbles. If you hit a pothole hard enough with a run flat, a bubble will appear and tire needs replacement.

how did you check them?
and what do you mean none "feel" flat
the proper way to check is to actually check the pressure. a completely deflated runflat will "look" fine

Just use a tire pressure gauge......"feeling" a tire for pressure is about as useful as looking at it to determine tire pressure.

Your car should be equipped with a Tire Pressure Monitoring system. Did you get any warning light on the instrument panel? Check the air pressures?

You should get rid of the rft's and buy reel tires anyway.

Checked pressure. All are at 32 except right rear is a 20. Carrying it to the tire shop tomorrow to get it checked. Been reading on hear a lot and seems like i should just get 4 regular tires and a spare.

People are very quick to bad mouth run flats, but it seems like they did just what they are designed for in this circumstance; mainly, got your daughter home safely on a flat tire.

If you had regular tires on the car, you probably would have gotten a call from her stuck on the side of the road with a flat tire (best case) or stuck in a ditch with a flat tire (worse case) or ??? (worst case).

Not sure why your TPMS didn't go into alarm though, that is strange, and you should have been aware to always check the pressure on low profile tires rather than simply looking at them. Run flat or not, low profile tires can have very little visual difference between properly inflated and severely underinflated, especially if the ground you are parked on is not billiard table flat.

I'm on my second set of run flats now and find them to be perfectly acceptable.
