TST on the Phaeton and Flex also TST on the B+ and an additional 4 sensors purchased for the Miata, it will be towing. We shredded a tire on a toad over 20 years ago and wrapped the tread around the spindle, lucky no damage to rim and old black residue and minor scratches on the fender. A TPMS was one of the 1st items we added when we went full time 11 years ago. Bought our 1st PressurePro system at an Escapade in Du Quion IL, the month we hit the road. Switched to TST after 3 or 4 of those PressurePro sensors had to be replaced, used the PressurePro system until, had 5 working on the B+. Really like TST's replaceable batteries.
