The importance of the tyres cannot be underestimated. These are what are attaching your vehicle to the ground, and must therefore be in the best condition possible.
After most have been sitting still for several months, visually check for cracks, splits and bulges. These can be on the side-wall, between the tread blocks or on the inner side-wall. Tyre pressures MUST be checked because they will have deflated naturally.
When it comes to replacing your tyres on your caravan or motorhome you must make sure that you are replacing like for like. We have just had a caravan in for service that had new tyres fitted last August, but upon checking them during the service, we noticed that the load rating on the fitted tyres was 690kg: this equates to 95 on the tyre load table. You can see this printed on the top line of the tyre information: Max. Load Rating 690 Kg (1521 LBS)
The caravan itself had a MTPLM (Max Technical Permitted Laden Mass) of 1420kg. (“Laden Mass” means when the caravan is fully loaded.)
So for a single axle caravan, two tyres of 690kg + 690kg = 1380kg. That is 40kg short of what the caravan can weigh, which makes the tyres unsafe as they will be overloaded when the caravan is full.
The tyres we replaced on the caravan were 710kg + 710kg = 1420kg, which means the tyres can take the fully packed weight of the caravan.
Moral of the story is check, check and double check that the replacement tyres you are ordering are correct – or bring your vehicle to us and we will make sure you get the right ones fitted first time. To cap it all, the tyre fitter had not even bothered balancing the wheel when he fitted the tyres. It is something we always do as other problems can occur from not doing so.
