Load index: Your tyre's load index relates to its maximum carrying capacity (in kg). You'll find the load rating of your tyre on the sidewall, just to the right of the diameter. For example, a tyre with a load index of 91 can carry 615kg of weight.

Does the load index on a tire matter?

Why Is Tire Load Index Important? The tire load index tells you how much weight your tire can carry, and overloading your tires is never a good idea! When you put too much weight on your tires, you can cause damage and wear them down prematurely. Even worse, you run the risk of experiencing a tire blowout.

How important is the load index on a tire?

The higher the tire's load index number, the greater its load carrying capacity. Choosing a tire with a lower load index than the original equipment specifications means that the tire will not carry the load capacity of the original. Most passenger-car tire load indexes range from 75 to 100, but some are higher.
