Tire Sidewall

The writing, lettering and symbols on the sidewall of your tire aren’t there simply to make it look good, they all explain you something about the specification of the tire.

That includes the speed at which the tire can safely be used, the loads it can carry, its width, which way round to mount it on the wheel, where it’s made and what safety standards it’s passed.
At first glance you might think all that information is hidden away in secret code, but if you follow our easy-to-use size tire size chart guide, you’ll see that there’s really no great mystery. The tire lettering and size are explained so you are able to read what the exact size your tires are.
