My Ride: 2005 530i Individual, DVD Package, HUD, Bluetooth, Comfort Seats, SR, etc
I am changing from 124 style wheels to 135 M wheels 18", I have to buy new tyres as the 124's have wider wheels and tyre spec in the rear wheels, so i decided to change to regular tyres when i get my new wheels, will this be a problem for the TPMS? are they installed inside the wheel? Is this fairly a simple un-install-install job or more complicated than that? Anyone have similar experience?

oh ok thanks.
And just another FYI here- All BMW 07's have switched to the sensor actually being inside the wheel attached to the metal valve stem. This is because the NHTSA has mandated that all auto manufacturers have this system in place for all 08' cars. They are trying to prevent accidents, since most people don't check their tire pressures regularly. I posted an article I found on the net below.
The National Highway Traffic Safety Administration (NHTSA) has mandated that all passenger vehicles made in the United States be equipped with tire pressure monitors for the 2008 model year. The rule requires that manufacturers install a system to detect when one or more of a vehicle's tires are 25% or more below the recommended inflation pressure.
Phase-in of the new regulation will begin Sept. 1 of this year. All new four-wheel vehicles weighing 10,000 pounds or less must be equipped with the monitoring system.
According to NHTSA, underinflated tires can adversely affect fuel economy and lead to skidding and loss of control and hydroplaning on wet surfaces. Tire underinflation can also increase stopping distance and the likelihood of tire failures.
The agency estimates that about 120 lives a year will be saved when all new vehicles are equipped with the tire pressure monitoring systems. In addition, consumers should see improved fuel economy and increased tire life. The manufacturers' average cost per vehicle for the system is estimated to be between $48.44 and $69.89, depending on the technology used.
The tire pressure monitoring system was required by Congress when it enacted the Transportation Recall Enhancement, Accountability and Documentation (TREAD) Act in 2000.
