Review on TST Tire Pressure Sensor Tow Car Pack: Enhance Performance with TST 507 Systems by Jose Cruz

I am happy with these TST Tire Pressure/Temperature Sensors. You probably aren't exactly accurate on either pressure or temperature, but every spike in your tires can be seen and observed. After carefully inflating all tires according to the manufacturer's recommendations, the tire pressure on each axle was only between 0 and 4 psi. While driving, the pressure changed more depending on the load on the tires, wind and sun exposure. I like the instant notification of a sudden lack of air or overheating.
