The TST 507 is the best-overall aftermarket TPMS, named the top pick by The Drive for its all-around features and clear color display. RV reviewers consistently report readings within a few PSI of calibrated gauges and credit it with catching slow leaks before they became blowouts. It costs more than car-focused budget units and its display can wash out in glare, but it is the most trusted system here.
- — Easy-to-read 3.5-inch color display with clear pressure and temperature
- — Cap sensors read consistently within a few PSI of calibrated gauges
- — Premium price versus budget car-focused TPMS units
