How to check your trailer tyres

Why is it important to check your trailer tyres regularly?

Before using your trailer it is important to check its tyres carefully. To help you do this, we have put together some tips and advice on how to check your tyres. Even if you have not used your trailer for some time the tyres may start to deteriorate with age, but there are steps you can take to slow this process down.

First look out for any obvious signs of age deterioration in the tyres such as cuts, lumps, embedded objects, sidewall cracking or carcass deformation. Trailer tyres that are on a stationary vehicle are always likely to age more quickly than those in regular and frequent use. Tyres exposed to coastal air are also prone to faster ageing.

Also, when you check your trailer tyres pay particular attention to the tread depth. Trailer tyres, like all car and light commercial vehicle tyres, must have a minimum tread depth of 1.6mm in order to be legal and roadworthy. However, in the interests of safety it is advisable to replace tyres well before they reach this legal limit.

Tyre pressure is essential to the safety and stability of your trailer. It is vital to check the pressures in all tyres when you complete a tyre check. Incorrect tyre pressure can have a catastrophic effect on the handling of the trailer and can also lead to dangerous tyre failure, including blowouts. Tyres that are incorrectly inflated will also wear out more quickly and increase the towing vehicle’s fuel consumption. It will therefore save you money if you maintain correct tyre pressures.

The correct inflation pressure for your trailer tyres will be given in the vehicle handbook. Tyre pressure should be checked and adjusted, if necessary, when the tyres are cold. Never reduce pressures when the tyres are warm, because the pressure could be too low when they cool down.


If you experience a puncture pull over to a safe place and check your trailer tyres for damage. It is also crucial to have the tyre on the other side of the axle examined, because it may have sustained damage whilst bearing an extra load.
