TST-507 Tire Pressure Monitoring System


The TST 507 is the best Tire Pressure Monitoring System (TPMS) on the market and the only one that includes a color monitor. The flow-thru sensor is very popular for those that want the convenience to air up tires without taking the sensor off the valve stem. (Recommended to use with metal valve stems; use the TST cap sensors for rubber valve stems.)

Note: This is the Flow-Thru system, which is what we have on the RV.  We have CAP sensors on the truck because the flow-thru sensors will not fit.
