Note The assumption that tires are more wear resistant after aging is not valid.
VR rated tires should not be used if older than 6 years. Age can be determined by the last three digits of the DOT code on the tire sidewall.
For example:
If the last three digits are 193, the tire was manufactured in the 19th week of 1983.
Wear
Excessive, rapid tire wear is usually attributed to driving habits.
Almost all tires have tread wear indicators specified for the U. S.
The tread wear indicator is a ridge across the tread base at 6 points on the circumference of the tire.
Tread wear indicators
The ridge has a height of 1.6 mm. When tread wear reaches this point, the ridges become visible. The appearance of the wear indicators signals the need
for tire replacement.
