Understanding Speed Rating & Load Indexes
Using a P205/65R15 94H tyre size as our example, the 94H at the end of the size represents the tyre’s
service description. The first two digits (94) represent the tyre’s load index and are
followed by a single letter (H) identifying the tyre’s speed rating.
P205/65R15 94H – The load index (94) is the tyre size’s assigned numerical value used to compare relative
load carrying capabilities. In the case of our example the 94 identifies the tyres ability to carry approximately 670
kilograms. The higher the tyre’s load index number, the greater its load carrying capacity.
