Frequently asked questions

The slim tyre is normally acceptable, subject to a maximum speed of 50mph and a distance limitation set by the manufacturer. A manufacturer will have provided a spare with a load index at least equivalent to your existing tyres, hence the loading will be acceptable. But, because of the great difference in road contact, caution is needed when braking and manoeuvring, whether towing or not.

Run-flat tyres are different, the additional flexibility of the deflated tyre may seriously affect the stability of the towing outfit. The car manufacturer should give guidance in the handbook, but be aware that towing may not be recommended or a low speed limit and very limited distance may be imposed.

There is no such thing as a caravan tyre, although some tyre sizes are supplied specifically to fit certain caravans. The same general specification is used for all road vehicle tyres and all are subject to the same rules on tread depth and construction. However, since the whole of a caravan’s weight is carried on just two tyres, the load carrying specification is usually higher. You should always ensure that the tyres fitted can carry the weight of the caravan at the speeds at which it could travel. A tyre fitter should have access to tables to work this out on the basis of tyre size and maximum weight of caravan, but if in doubt consult one of the Approved Caravan Workshops.

When you have the correct tyres fitted it is also important to inflate them to the correct pressure. If you do not have the caravan's handbook available, again your Approved Workshop should be able to help you. Remember that using a tyre which is ‘unsuitable’ for its use is against the law.
