5. 15: Indicates the wheel or rim diameter in inches. If you change
your wheel size, you will have to purchase new tires to match the
new wheel diameter.
6. 95: Indicates the tire's load index. It is an index that relates to how
much weight a tire can carry. You may find this information in your
Owner's Guide. If not, contact a local tire dealer.
Note: You may not find this information on all tires because it is not
required by federal law.
7. H: Indicates the tire's speed rating. The speed rating denotes the
speed at which a tire is designed to be driven for extended periods
of time under a standard condition of load and inflation pressure.
The tires on your vehicle may operate at different conditions for load
and inflation pressure. These speed ratings may need to be adjusted
for the difference in conditions. The ratings range from 81 mph (130
km/h) to 186 mph (299 km/h). These ratings are listed in the
following chart.
