It is strongly recommended that a compatible spare wheel and tyre assembly is carried for the caravan. As caravan tyres and wheels are rarely the same as those on the towing vehicle, the spare tyre and wheel assembly from the towing vehicle must not be used on the caravan, even in an emergency situation. The caravan spare tyre should be the same size, load index and speed rating to those already fitted to the axle.
When checking the pressures and condition of the tyres on the towing vehicle, remember to check the spare tyre as well.
Adequate tread depth is vitally important for road safety. The tread grooves help to evacuate water from the road surface. If tread depths are not sufficient stopping distances increase, there is a higher risk of aquaplaning and vehicle safety is reduced.
Furthermore drivers can face penalty points and fines if tyres are found with tread depth below the legal limit. To ensure compliance with tread depth regulations across Europe, a minimum tread depth of 1.6mm across the full tread width is recommended. In the interests of safety it is advisable to replace tyres before they reach this legal minimum limit.
