| Tyre Pressure |
| |
| There are a number of points that need to be made before you can talk about the perfect tyre pressure for your vehicle.
There is a Maximum Tyre Pressure Listed on the Sidewall of all Tyres, this pressure is an indication of the Maximum Pressure, and is not necessarily the Recommended or Best Tyre Pressure For your Vehicle.
Tyre Pressure Changes as the Tyre Gets Hotter and the Rubber Expands, most information relating to Tyre Pressure is based on Cold Tyres.
A General Rule for Tyre Pressures is the less pressure the softer the ride, but this affects both Handling, Fuel Consumption and Tyre Tread Wear Negitively. High Tyre Pressure Improves Tyre Tread Wear Most, Creating less friction with the Road, this in turn improves fuel economy. High Tyre Pressure increases Handling Capabilities of a vehicle, due to the harder tyres improving feedback from the Road Surface.
The following material is a guide only, always check the manufacturers Tyre Placard on your vehicle for both the Recommended Tyre Sizing and Recommended Tyre Pressure (The Tyre Placard usually found in the Driver's Door Sill, In the Glove Box, under the petrol filling flap or under the bonnet.) The manufacturers information is always the most relevant as it relates directly to your vehicle. Charts are based on Cold Tyre Pressure.
There are a Number of chart below, the first are listed in Psi, Psi is a standard unit of measurement within the tyre industry, it refers to Pounds of Force per Square Inch. The second Charts refer to kPa, kPa is not as commonly used as psi, but is listed on almost all Tyre Pressure guages. We have already done the Conversion for your convenience on the charts below. |
