’s quite interesting to note that there are no tyres made specifically for use on caravans or motorhomes. You may find businesses that claim to sell caravan tyres, but they will simply be tyres for vans - or sometimes cars! Car tyres can be suitable for caravans, but with the extra load, tyres that are recommended for vans that come with a "CP" rating (i.e. commercial use) are generally a good choice. If you are looking at standard car tyres, then extra loads are a must. Remember, it’s not just the weight of the caravan that your tyres have to support, but also all the contents, and that can really add up. So paying close attention to the load rating of your tyres is vital. A blow out on your holiday would be so disappointing, and potentially very dangerous.
For motorhomes, particularly the mid to large sized ones, most will certainly be best with "C" or "CP" rated commercial tyres. You should also pay particular attention to the configuration of the tyres, particularly if you are running a tandem or twin rear axle configuration. Some C and CP marked tyres will come with two load indexes, with the first and second number representing a different load rating for that tyre depending on which axel configuration it is being fitted to.
Did you know In some European countries it is illegal to use replacement tyres which differ in size, load, and speed rating from the tyre fitted originally by the vehicle manufacturer?
