One of the most important, safety critical ratings that is found on the sidewall of a car tyre - is the load index rating. It’s represented by the last two numbers on the tyre size, and the two numbers, starting at 62 and ending at 126 (on passenger vehicles and vans) - represent the maximum weight that the each tyre is approved to carry. Although the rating does vary between tyres, typically the same size car tyre will all have the same load rating, unless the wheel sizes differ.

Low profile tyres, which are increasingly popular in modern vehicles - typically have a lower load rating, but remain a safe choice when fitted as standard by manufacturers. Issues only arise if a motorist fits low profile tyres to a heavy SUV or 4x4. Whenever you change or replace tyres or even wheels on your vehicle, the load rating should always be the same as the original - or higher. The load rating should never be lower.

Larger and heavier vehicles, are often equipped with tyres which are marked XL - this means that the tyre has been reinforced for vehicles which are both heavier, or vehicles like estate cars which are designed to carry more people or heavier loads.
