Incorrect tyre pressure can reduce the life of your tyres, and make your car less safe to drive. Check and adjust pressure when tyres are cold. You will find your car’s correct tyre pressure on the tyre placard on the inside of your glovebox, fuel cap filler, or inside the driver’s door opening. You should check for a minimum tread depth of 1.5mm on any part of the tyre surface that comes into contact with the road. Tyres have indicators in their tread pattern which show (as lines across the tread) when worn down to 1.6mm. Check your tyres for abnormal wear or damage (such as cracks, bulges or tears). Note: You should buy your own tyre gauge to check pressure because service station gauges may not be accurate.
