Hey guys, I'm looking to buy some TPMS for my 2010 E550. I'm using these on a new set of wheels.

Any recommendations on where to buy? I found some brand new OEM ones for a good price but not sure if any of you guys have dealt with this company before?

Any problems with buying a used set?

I bought mine from tirerack.com. A new set with them should be around the same price. But buying a used set shouldn't be a problem as long as they are compatible with the car.

we have them ... just give us a call
