I went to have my new wheels put on today, and am using my stock tires. The guy told me I would have to buy new seals to put on my TPMS around the valve stem if I wanted to mount them in the new wheel. If not, then there would be a leak.Anyone else dealt with this? If I chose not to mount the TPMS, I could just use regular valve stems, and deal with that annoying warning light, right? Thanks for any opinions.

I had 19's installed and had leaks
so I brought the car back and the tire shop played with the stems and got the leaks to stop. I didn't have to buy any spacers or extra parts.

 

Makes sense to me as the old ones would be deformed and may not seal very well.

A rule of thumb for any type of maintenance is to never reuse an O-ring, always replace!
