All-Season Tyres; Winter Tyres - Cadillac XT4 Owner's Manual

272 VEHICLE CARE
Warning (Continued)
Underinflated tyres pose
the same danger as
overloaded tyres. The
resulting crash could cause
serious injury. Check all
tyres frequently to
maintain the
recommended pressure.
Tyre pressure should be
checked when the tyres
are cold.
Overinflated tyres are
more likely to be cut,
punctured, or broken by a
sudden impact - such as
when hitting a pothole.
Keep tyres at the
recommended pressure.
Worn or old tyres can
cause a crash. If the tread
is badly worn,
replace them.
Warning (Continued)
Replace any tyres that
have been damaged by
impacts with potholes,
curbs, etc.
Improperly repaired tyres
can cause a crash. Only
the dealer or an authorised
tyre service centre should
repair, replace, dismount,
and mount the tyres.
Do not spin the tyres in
excess of 56 km/h
(35 mph) on slippery
surfaces such as snow,
mud, ice, etc. Excessive
spinning may cause the
tyres to explode.
See Tyre Pressure for High-Speed
Operation 0 275 for inflation
pressure adjustment for
high-speed driving.

All-Season Tyres

This vehicle may come with all-season
tyres. These tyres are designed to
provide good overall performance on
most road surfaces and weather
conditions. Original equipment tyres
designed to GM's specific tyre
performance criteria have a TPC
specification code moulded onto the
sidewall. Original equipment
all-season tyres can be identified by
the last two characters of this TPC
code, which will be MS.
Consider installing winter tyres on the
vehicle if frequent driving on snow or
ice-covered roads is expected.
All-season tyres provide adequate
performance for most winter driving
conditions, but they may not offer the
same level of traction or performance
as winter tyres on snow or ice-covered
roads. See Winter Tyres 0 272.

Winter Tyres

This vehicle was not originally
equipped with winter tyres. Winter
tyres are designed for increased
