When It Is Time for New Tires
One way to tell when it is time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. Some commercial truck tires may not have treadwear indicators.
You need a new tire if any of the following statements are true:
• You can see the indicators at three or more
places around the tire.
• You can see cord or fabric showing through
the tire’s rubber.
• The tread or sidewall is cracked, cut or
snagged deep enough to show cord or fabric.
• The tire has a bump, bulge, or split.
• The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.
