service indicator Alfa Romeo 4C Spider 2018 User Guide

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread
depth becomes a 1/16 of an inch (1.6 mm). When the
tread is worn to the tread wear indicators, the tire
should be replaced. Refer to “Replacement Tires” in this
section for further information.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style.
• Tire pressure - Improper cold tire inflation pressures
can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle
scheduled maintenance is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire fail-
ure. You could lose control and have a collision
resulting in serious injury or death.
