How to read a UK load index
- It's the number just after the rim size (e.g. R16 91V)
- It maps to a maximum weight per tyre in kg
- A higher index means a stronger tyre — that's safer, never less safe
- For vans, look for two numbers separated by a slash (single / dual)
- XL or HL means “extra load” reinforced construction
Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What is the load index on a tyre?
The load index is a numeric code on the sidewall that maps to a maximum weight each tyre can carry, in kilograms.
Where do I find the load index?
On the sidewall, between the rim size and the speed rating. For example, in 205/55 R16 91V, the load index is 91.
Can I fit a tyre with a lower load index?
No. Replacement tyres must meet or exceed the original load index. A lower index can affect safety, MOT compliance and insurance.
Why do vans use higher load indexes?
Vans carry more weight, so they need C-rated commercial tyres with higher load indexes. Two figures (e.g. 109/107) show single and dual load ratings.
