Hey everyone, I recently upgraded my wheels and forgot to take off the TPMS of the old set. I plan to take them off soon and have them installed later when I get a moment, but is there a way to turn off the Flat Tire Warning permanently? Every other time i start my car now, it pops right up and i have to disable it again. I have a 04 545i, with 20" wheels, tires are 295/25/20 and 245/30/20...

Thoughts?

 

I'm pretty sure your car doesn't have TPMS. You need to go into your iDrive setting and just recalibrate the Flat Tire Monitor (FTM). Piece of cake should only take you 2 minutes.

That would be correct, your year model has FTM, not TPMS.

 

My FTM goes off randomly but tires are always fine. Any ideas?

 

Check your tire pressure and reset the FTM. If it keeps happening there's something wrong with your FTM or one of your tires.

Used to happen to me too, could be the weather or maybe a very slow leak. Invest in a good pressure gauge, so you can see if the pressure is really dropping and by how much and you can also inflate to the correct pressure. WHICH SAVES GAS!

 

my tire has a slow leak...just found it. the bead wasnt in the best shape when i put them on...i guess now im paying for it. anyone know if the bead can be repaired to sealed tight w/ some type of goup at the tire shop? or should i just prepare to shell out $350 for a new tire (im running Michelin Pilot PS2s)...

thanks!

 

I haven't heard of anyone being able to repair beads.
