Why TPMS?
TPMS –Tire Pressure Monitoring System
Most people ignore their tires. Tires are undoubtedly the most critical safety component on a vehicle. Where the rubber meets the road affects traction, handling, steering, stability and braking. Becau of this, a sudden tire failure can have rious conquences, especially if it occurs at highway speeds. Yet people neglect their tires and assume that all is well unless they appear totally flat, at which point it is too late!
The best tread designs and the most expensive tires are nothing without the air that carries them along. Monitoring tire air pressures is such a small investment in time compared to the costs related to replacing tires put out of rvice becau of improper inflation.
