Load index is a number ranging from 0 to 270 that references
with the load carrying capacity of a tire. Most passenger car tire
load index range from 75 to 105. The higher the load index number
the more load carrying capacity they have.
Using the example picture above, tire size 225/65R16 89H, the load
index of 89 corresponds to a load carrying capacity of 1279 lbs.
The H is a reference to the speed rating. As you can see in the
above speed rating chart H is speed rated up to 130mph. |
