A new system from TyrePal makes it easy to monitor tyre pressures with a display at your driving position. The system uses valve-cap sensors to transmit accurate pressure and temperature data from your tyres. Cornering, steering, road-holding, fuel use and tyre wear all critically rely on four small patches of rubber in contact with the road, so serious attention to tyre pressures pays off in regular road use as well as in race performance. The system continuously displays pressure for each tyre and gives a leak alarm and alerts for low pressure. For performance users, tyre temperature can be displayed by pushing a button, and there are high pressure and high temperature alerts. Alert thresholds are all adjustable from the default settings. Installation is quick and easy. Just screw the sensors onto the tyres in place of standard valve caps and fit the anti-theft collars if required. Position the monitor on the bracket in view of the driver and the job’s done. There’s no need to remove the tyres, no programming and generally no need to even rebalance the wheels. No wiring is required. Power for the monitor can be from internal batteries that last about six months or from the vehicle’s 12V power supply with the plug-in connector provided. Lithium batteries in the valve-cap sensors last 1 to 2 years and are replaceable. Pressure can be displayed in psi, bar or KPa, with an accuracy ±1psi. Maximum pressure is 60psi, suitable for most cars, with a high pressure version also available. Temperature in C or F is accurate to 2C.
