Tire Pressure Indicator - The Unofficial BMW M5 Messageboard (m5board.com)

So . . .having just gone to aftermarket rims and tires, I assume my tire pressure indicator will not function.

Are there sending units inside the stock wheel/tire combination that should be removed and re-installed inside the new aftermarket wheels and tires?

I know many of you have replaced your stock wheels and tires. What have you done to enable the stock tire pressure indicator on the dash to work?

this has been discussed quite a lot on the board already... The way the tire pressure monitor works is it senses the rotational speed on each tire.. when one tire differs from the others, it will send the warning.. so putting on aftermarket wheels shouldn't be a problem.. you just have to make sure you reset the tire pressure monitor and calibrate it again, as per instructions in the manual...

this raises a really good point though, and if i'd thought about it in time, i would have really looked at the aftermarket pressure sensor that really measures tire presssure when i put on the new wheels -- much more accurate than the OEM estimate or rolling radius -- and tells you the accurate pressure for each tire, can't remember who makes it

anybody with experience?
