I have read some past threads about TPMS. What i was looking for was information about damage to the valve stem. Some reviews for the TPMS that screw onto to the stem claim that their stems were damaged. I was planing to add a TPMS to LT that I just brought home however, I was surprised to find rubber valve stems not the thread metal like on my ST. If anyone has luck good or bad with screw on TPMS I would to hear.
