After having a flat tyre on a motorway in France I feel a lot more safe knowing i now know exactly what pressures my tyres are whilst traveling. It gives a warning when tyre pressures stop or exceed user set levels. It also displays temperature of each tyre. This system costs around £100 but in my opinion well worth it. The senders replace the tyre valve caps and the receiver is solar powered and sits on top of the dash.
