When It Is Time for New Tires

Various factors, such as maintenance, temperatures,

driving speeds, vehicle loading, and road conditions,

inﬂuence when you need new tires.

One way to tell when it is

time for new tires is to

check the treadwear

indicators, which 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 new tires 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.

The rubber in tires degrades over time, even if they are

not being used. This is also true for the spare tire, if your

vehicle has one. Multiple conditions affect how fast this

aging takes place, including temperatures, loading

conditions, and inﬂation pressure maintenance. With

proper care and maintenance tires will typically wear out

before they degrade due to age. If you are unsure about

the need to replace your tires as they get older, consult

the tire manufacturer for more information.
