There is a small automotive shop (one man show owner/operator) I asked him if he has mounted tires that use TPMS and he said yes "you just have to be very careful". Anyways he'll mount and balance my snow tires for $12.50/each ($50 total) which is way cheaper than anyone else. What really goes into mounting/dismounting tires with TPMS? I've heard about "rebuild kits" being needed sometimes, etc. This shop is literally across the street from my house and I know he's changing out a lot of snow tires including newer cars with TPMS because I can see them from my window. Any advice would be helpful.
