dealer must have meant TPM sensors.... funny how they try to act technical and stuff...

i'm sure that's what he meant...

thanks for the replies. I was planning on getting the 214 20s later (replica or OEM, whichever I find first and at a descent price) and wanted to make sure there weren't any issues with swapping them out myself.

i guess as long as i have them installed and balanced, and with the TPM sensors, i'll be fine..
