Look out for tyres marked ‘C’ or ‘CP’ as these denote light commercial tyres suitable for these types of vehicles. These tyres are specifically engineered to carry the extra load imposed by these heavier body types.
It is important to ensure that you do not deviate from the manufacturers original specifications as this may affect the handling characteristics of your vehicle. It is also important to ensure that your vehicle is not overloaded and that the tyre pressures are consistent with the load being carried.

Caravan Tyre Information
It may be surprising, but caravan tyres are not made specifically for the use of caravans but are the same tyres we use on cars or small commercial vans. However, they’re used differently as they don’t need to cope with high-speed braking but do need to accommodate increased pressure from heavier loads.
Here are four things to consider when it comes to caravan tyres.
It is the responsibility of the driver to ensure that the correct tyres are fitted to the caravan as indicated by the manufacturer’s guidelines. Tyres must be the same size across the axle and meet the same load index and speed rating. It is vital to stay on top of these requirements as failure to comply could result in a fine of up to £2,500 and 3 penalty points issued per tyre.
Like all car tyres and light commercial vehicle tyres, the minimum tread depth for caravan tyres is 1.6mm. Caravan tyres have additional considerations when it comes to tyre tread as, due to their relatively low mileage and reduced time spent on the road, the rubber and overall tyre quality can deteriorate. Replacing your caravan tyres every three years is standard practice to maintain a good safe tyre.
The noseweight of a caravan is an essential element for vehicle balance. It should be determined by the laden weight of the caravan for the optimum unit for towing. The size and type of vehicle towing the caravan will have an impact upon this. It is estimated that this is set at 7% of the laden weight.
Extending the life of your caravan tyres is easy. Examine them for any signs of damage and give them a quick clean to remove and traces of material that can deteriorate the rubber, such as petrol. If you are removing your caravan or motorhome tyres, make sure you cover them from the sun as UV rays can be particularly harmful. It’s also advisable that your caravan is securely jacked up to release pressure from the tyres. As long as they are turned regularly throughout the storage process their shelf life will be prolonged.
Are caravan tyres different to car tyres?
No, there are no differences between them. However, while both can be either radial-ply or cross-ply, it’s illegal to include both varieties on the same axle.
What pressure should caravan tyres be?
The safety and durability of your caravan tyres is dependent on inflation pressure. Every tyre has an optimum inflation pressure based on the load it’s carrying. As caravans generally operate at, or close to, their maximum weight, it’s good practice to select the optimum pressure for that particular load.
However, if your caravan is used significantly below its maximum weight, it’s best to opt for the optimum inflation pressure of its true laden weight, which can be confirmed by using a weighbridge.
Regarding commercial tyres; bear in mind that they’re designed to operate over a wide spectrum of loads and can differ significantly when used on a caravan. For example, a tyre with a maximum inflation pressure of 52psi may require a pressure closer to 30psi when used on a caravan.
Lastly, remember that incorrect inflation pressure can adversely affect your caravan’s handling and can thus reduce its fuel efficiency.
How often should caravan tyres be replaced?
It’s generally accepted in the caravan industry that tyres should be changed around the five-year mark, even if they appear to be in pristine condition. Laws in The Netherlands, for instance, reinforce this sentiment, as caravans cannot not pass their MOT if their tyres are more than six years old.
Failure to follow these guidelines can result in a blow out that can cause severe damage to the caravan.
It’s also worth noting that heavy, single axle caravans are particularly susceptible to the effects of tyre neglect. If you own one of these types and the tyre’s running at 50psi or more, be sure to get them checked regularly after the three-year mark.
Do caravan tyres need balancing?
Wheel balancing is not a strict requirement as most imbalances will not be felt when towing or during transit. However, there’s harm in getting your wheels balanced for peace of mind and to ensure your caravan ride is as smooth as possible.
