Load Index markings – what the numbers mean
Similar to Speed Rating, every tyre on the market has a Load Index indicator. Expressed as a two or three digit number, the load index tells you what the maximum allowed weight your tyre can carry.
Some tyres have a dual rating, for example “96/94N”, where the 96/94 is the load index. Whenever there are two numbers shown like this, this is for multiple-axle applications. On a single axle trailer, the higher “96” rating applies, so each tyre is rated at 710kg. The tyre rating across the axle would therefore be 710 x 2 = 1420kg.
On multi-axle trailers, always use the second figure, in this instance “94”. The “94” denotes it has a load rating of 670kg per tyre, so on a twin axle trailer it would be 670 x 2 x 2 = 2680kg
Please Note: The figures above show the only load rating of the tyres – always consult your trailer chassis plate to see what your trailer is plated at. Your axles may not be rated as highly as the tyres.
