Hey all:

Need to pick up a set of TPMS sensors for the summer wheels and tires.
Anyone have any tips on getting this done at non-OEM prices - haha.

Thanks!

Not sure where you are, but when I ordered a set of wheels/tires for winter use from TireRack, they installed compatible TPMS sensors. They may sell them separately, so you could give them a call. I would think any tire shop could tell you what you need. They don't have to be Mercedes brand.

Here's some from ECS Tuning for under $25 each.

Same with me. When I purchased my wheels the TPMS came installed. I think in general any tire shop can get the ones he needs.
