Appendix B: Tyre load index tables
Tyre load rating and exceptions, and tyre load index tables for single wheel and dual wheel configurations for car and passenger vehicle MOT tests.
Check the manufacturer’s plate to find the maximum laden weight of an axle. You must check that the tyres fitted have a load rating that can carry the laden weight of the axle.
If the manufacturer’s plate does not show the laden weight of the axle, you can assume the tyres are suitable, unless it’s beyond doubt that they’re not suitable.
If a Class 5 or 7 vehicle has a ‘ministry’ plate, you should use the lower axle weight not to be exceeded in Great Britain shown on the ‘ministry’ plate rather than the laden weight shown on the manufacturer’s plate.
If a tyre is not marked with a load index, you must assume it meets the load capacity requirements.
The tyre load index table displayed below shows the load rating for both single wheel and dual wheel configurations, for example 121/120 = 2,900 single, 5,600 dual.
If a tyre has only one load index marked, then that index refers to use in single formation. Such tyres can be used in dual formation by applying the following formula:
Maximum load shown × 1.91 = dual formation maximum load
