Wahoo, I just bought a set of 7.5 x 17 pro-race 1.2 (in bronze!). I have 12K on my stock tires which still have some life (and value), but I?m thinking I?d be better off with new rubber. I?d also like to keep the stock tires for later use (autox), or sell them with the stock rubber on. Taking the TPMS out of the stockers is an additional expense to remount the stock tires on the stock wheels not to mention they won?t have TPMS installed if the buyer needs them, so do I go with new TPMS inside the new wheels, or put them in a PVC pipe so I can keep all options open? I?ll likely have this done at my dealer who sells tires very cheap so they can reprogram the TPMS. So what are you guys doing in my situation? Is keeping the stock TPMS worth the effort and expense? How much is all this going to cost?
