tire pressure sensor question
how are the tire pressure sensors mounted in the stock wheels? i have a set of aftermarket wheels coming and was wondering how hard it would be to mount the sensors in them? any suggestions from the people that have done this?

If the wheels are compatible, you just unscrew the sensors and swap them. If the wheels are not TPMS-compatible, you're kind of stuck. But most wheels nowadays are compatible.
I think you're supposed to use new o-rings or something, but tire places have the required parts in stock.

Look in the tire and wheel section here on the boards.Get Luke from Tireracks ext. and call him,he will get you the right TPMS to use with your wheels and a fraction of what the dealer charges.

the 63's i know for a fact have actual physical tire pressure sensors, meaning you dont have to be in motion for the computer to calculate whether you have a flat/less air in the tire(s)...

a car that gets very poor gas mileage.
the 55's (what you have) is passive... its some sort of calculation based on the standard rate of rotation of the wheels vs the rate it rotates with less air pressure...

My 55 shows psi for ea tire. I verified the reading within .5 psi accuracy for each tire with a digital tire presssure guage.

This passive way of displaying Ok or not Ok is terrible, because by the time I get any warnings for low tire pressue, it will be too late. I guess I'll go with my traditional accutire gauge to make sure the pressures don't drop below the dangerous level that can damage the wheel.

If you have the TPMS that reads out the actual pressures of each wheel like the CL class, the valves are metal. If you have the passive type the valves are the usual rubber. The passive I believe uses the ABS to measure wheel rotation, so if the vehicle is going straight and one wheel is turning faster it must be losing pressure. My '06 CLS55 has passive TPMS. Hope this helps.

Is this due to different sensors use between US and Canada models?

No, it's simply due to the TPMS software configuration being different in the US vs Canada. Just like how in Canada you can get rear heated seats and other options for the W211 that are not available in the US. Or, memory seats, C350 4Matic, etc which are also available in Canada but not the US. Here in the US we pay a bit less, but we also get quite a bit less.
