Ring Analogue Tyre Pressure & Thread Depth Tool Product Overview Product Details The RTG2 is a complete analogue tyre gauge set, which will give you a full picture of the condition of your tyres. Tyre gauges are an essential part of tyre maintenance. This set is small, easy to store and ideal to have in your vehicle for when they are needed – they don-t require any batteries or power, so they are always ready to use. No fuss. The pressure gauge shows readings in both BAR and PSI, showing pressures between 0-8 BAR, and 0-120PSI. The tread gauge will show the depth of tread, letting you know if your tyres are legally compliant, and, therefore, safe on the road.
