NORMAL
Even tread wear on this tire indicates that it has been properly maintained
and run at correct inflation pressure.
EXCESSIVE
Worn to the breaker/casing plies, the tire should not be left in
service or retreaded.
OVERINFLATION
Continuous overinflation accelerates center tread wear. It reduces
traction while making tread more susceptible to cutting.
UNDERINFLATION
Excessive tread shoulder wear results from chronic underinflation.
It increases the chance of damaging shoulders and sidewalls which
shortens tire life because of excessive flex heating.
