How often should I check tyre pressures?

Use the manufacturer's pressure for the load being carried, usually shown in the handbook, fuel flap or door area. Do not use the maximum pressure printed on the tyre sidewall as your normal target.

Hot tyres can read higher, which is why cold checks are more reliable.

Incorrect pressure affects steering, braking, fuel use and tyre wear. Recheck before long journeys or when carrying unusually heavy loads.
