The Steelmate TP-S7 Internal tyre pressure monitoring system (TPMS)

The all new Steelmate TPS7 Internal Tyre Pressure Monitoring Sensors is in town! Sleeker, better and more energy efficient than ever – solar powered color display TPMS

The system comes with 4 internal sensors and a solar colored powered dashboard mountable display which shows the tyre pressures of all 4 tyres in BAR or PSI. The display features audible and visual warnings when a tyre pressure drops below or raises above the recommended level. All sensors come pre paired to the correct wheel position and are labelled for easy installation, simply install each sensor onto the vehicle internal valve stem. Internal Sensors require re-balancing and re-pairing.

*Available in Internal Sensors Only
