When It Is Time For New; Tyres - Chevrolet Corvette Owner's Manual

264 Vehicle Care
Reset the Tyre Pressure Monitor
System. See Tyre Pressure
Monitor Operation 0 261.
Check that all wheel nuts are
properly tightened. See Wheel
Nut Torque under Capacities
and Specifications 0 301.
Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the centre of the
wheel hub with wheel bearing
grease after a wheel change or
tyre rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.

When It Is Time for New

Tyres

Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tyres.
Tread wear indicators are one way
to tell when it is time for new tyres.
Pilot Sport CUP2 Tyres
1. Treadwear Bars
2. Treadwear Indicator
Indentations
Pilot Sport CUP2 tyres have two
types of wear indicators located in
the tread area of the tyre to help
identify when it is time to replace the
tyres.
Treadwear indicator indentations (2)
are located on the outboard side of
the tread at the bottom of some of
the grooves. When this indentation
is no longer visible, the tread is
worn to 1.6 mm (2/32 in) and the
tyre should be replaced.
Treadwear bars (1) will appear even
with the tread when the tyres have
1.6 mm (2/32 in) or less of tread
depth and should be replaced.
