ARTICLE - What is load index and why does it matter?


The load index indicates how much load the tire can carry at a given speed. If you exceed the load index you risk tire failure. To calculate your total load capacity you need to add the load from the front and rear tires together.

You can find the load index for the tire as shown at left. The load index is often near the speed rating.

In this case the load index is 72 which equates to 783 pounds on the chart below.

You can take the load index number from the motorcycle tire for both the front and rear and look up the pounds each tire can carry.  Add them together and your load should not exceed this number or you risk premature tire wear and/or failure.
