Depends what model and how old it Is.
The light comes on the dash right above the odometer.
Some BMW's are fitted with 'run-flat' tires. If it is, it is not provide/sold with a spare tire because the 'run-flats' will allow you to do 90 miles on a flat and this will be enough to allow you to drive to a garage and have the tire replaced (they can not be mended). In other words your BMW may not have a spare tire.
Drive up to 100km and crash your car to a road divider.
If you go to any tire store they can reset it.
The Z4 does not have as spare tire. Run flat tires are used.
It is in the Owner's Manual.
WD40 and a few kicks.
Low tire pressure or tire pressure system malfunction
It is in the trunk where there would normally be a spare tire. The BMW 650i does not have a spare tire as it has run flat tires and does not need one.
bmw 645ci drivers rear passenger tire replaced brand new tire twice is now flat againand has been checked out by three different tire dealers unable to find the problem...car is 2005 and I am second owner car has only 34000 miles
It is under the floor in the trunk unless the car has run flat tires. In that case you will not have a spare tire.
