Caravan Tyre Ratings Explained

Many people think that caravan tyres are different from car tyres and so car tyres should not be fitted to a caravan. It’s true that caravan tyres are closer to van tyres because they carry heavier loads, but what really matters is the tyre’s load rating or load index. Irrespective of tyre type, it must be sufficient to cope with the vehicle’s maximum laden weight. Read our caravan tyre ratings article for more information…

Caravan Tyre Ratings Explained


For example, a single axle caravan with a maximum weight of 1500kg needs each wheel to be able to carry half this load – 750kg. The caravan manufacturer applies a safety margin of around 20%, so the tyres need a load rating of 900kg.

A tyre for this situation might be specified as 185 R14 104. This means it is 185mm wide, fits on a 14-inch rim and its load index is 104. There may also be another number after the width: that is the aspect ratio of the tyre. When replacing a caravan tyre you must ensure the new tyre has at least the load index specified by the caravan manufacturer.

The speed rating of the tyre is not so important on a caravan as you’re unlikely to ever exceed even the lowest limit. The rating is a capital letter between N and Y. N means the tyre works up to 87 mph and Y will work up to 186mph.

It’s important that the tyres on each axle are identical and to replace them both together. This helps ensure the caravan reacts evenly to forces, such as crosswinds.
