When the tread is worn
down to 1/16th of an
inch (2 mm), tires
must be replaced to
prevent your vehicle
from skidding and
hydroplaning. Built-in treadwear indicators, or “wear
bars”, which look like narrow strips of smooth
rubber across the tread will appear on the tire when
the tread is worn down to 1/16th of an inch (2 mm).
When you see these “wear bars”, the tire is worn out
and should be replaced.
Inspect your tires frequently for any of the following
conditions and replace them if one or more of the
following conditions exist:
• Fabric showing through the tire rubber
• Bulges in the tread or sidewalls
• Cracks or cuts on the sidewalls
• Cracks in the tread groove
• Impact damage resulting from use
• Separation in the tread
• Separation in the sidewall
• Severe abrasion on the sidewall
If your vehicle has a leak in the exhaust system, a
road tire or the spare tire may be exposed to hot
exhaust temperatures requiring the tire to be
replaced.
Tire Replacement Requirements
Your vehicle is equipped with tires designed to
provide safe ride and handling capability.
