Wheels and Tires
5. Wheel diameter
This two-digit number is the diameter of the wheel rim in
inches.
6. Load index
This two- or three-digit number is the tire's load index, which is
a measurement of how much weight each tire can support. This
number is not always shown.
7. Speed rating
The speed rating, when stated, denotes the maximum speed at
which the tire should be used for extended periods. The ratings
range from 99 mph (160 km/h) to 186 mph (300 km/h). These
ratings are listed in the following table:
8. US DOT Tire Identification Number (TIN)
This begins with the letters “DOT” and indicates that the tire
meets all federal standards. The next two numbers or letters are
the plant code where it was manufactured, and the last four
numbers represent the week and year the tire was built (for
example, “
1706
” would mean the 17th week of 2006). The
remaining numbers are marketing codes used at the
manufacturer's discretion. This information can be used to
contact consumers if a tire defect requires a recall.
9. Maximum permissible inflation pressure
This is the maximum inflation pressure for the tire. This
pressure should not be used for normal driving.
10. Treadwear grade
This number indicates the tire's wear rate. The higher the
treadwear number is, the longer it should take for the tread to
wear down. For example, a tire rated at 400 will last twice as
long as a tire rated at 200.
11. Traction grade
This letter indicates a tire's ability to stop on wet pavement. A
higher-graded tire should allow you to stop your vehicle on wet
roads in a shorter distance than a tire with a lower grade.
Traction is graded from highest to lowest as
