Tire change question

[jrbuete]

Finally gonna change my stock tires after 9000 miles. I've done this on countless street and dirt bikes with tire irons, elbow grease and some occasional colorful phrases but never a BMW with the tire pressure sensors...
A few simple questions:
1. I have the spoke wheels, treat pretty much like normal wheels, right?
2. Where/how do the tire pressure sensors work? Are they part of the valve stem or something
3. Are they fragile?
4. Would I be better off paying the $25 per wheel to get them mounted???
5. Any other issues to worry about?

Thanks!

I believe the factory TPS monitor is part of the valve stem. Don't break the bead by the valve stem and take a bit of care with your tire irons and you'll have no problem.

I don't have any problems with tire iron and my after market sensors.

Hey jrbuete,

I'm glad you asked the question! I'm about to practice changing a tire myself,and any info is great! On my wheels(spoke) there's a sticker just a bit to one side of the valve stem showing the sensor position. Not that I was doudting Marc, i'm just glad I had a reminder to keep an eye on the sensor when I take my tires off! Let us know how you made out!

$25 per wheel sounds like a pretty good deal to me!
