Different Size Tyres And Wheels; Wheel Alignment And Tyre; Balance - Cadillac XT4 Owner's Manual

Warning
Using bias-ply tyres on the
vehicle may cause the wheel rim
flanges to develop cracks after
many miles of driving. A tyre
and/or wheel could fail suddenly
and cause a crash. Use only
radial-ply tyres with the wheels
on the vehicle.
Winter tyres with the same speed
rating as the original equipment
tyres may not be available for H,
V, W, Y and ZR speed rated tyres.
Never exceed the winter tyres'
maximum speed capability when
using winter tyres with a lower
speed rating.
If the vehicle tyres must be
replaced with a tyre that does not
have a TPC Spec number, make
sure they are the same size, load
range, speed rating, and
construction (radial) as the
original tyres.
The Tyre and Loading Information
label indicates the original
equipment tyres on the vehicle.
See Vehicle Load Limits 0 200.
Different Size Tyres and
Wheels
If wheels or tyres are installed that are
a different size than the original
equipment wheels and tyres, vehicle
performance, including its braking,
ride and handling characteristics,
stability, and resistance to rollover
may be affected. If the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, electronic stability control,
or All-Wheel Drive, the performance
of these systems can also be affected.
Warning
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tyres not recommended for those
wheels are selected. This increases
the chance of a crash and serious

injury. Only use GM specific wheel
and tyre systems developed for the
vehicle, and have them properly
installed by a GM certified
technician.

Wheel Alignment and Tyre

Balance

The tyres and wheels were aligned and
balanced at the factory to provide the
longest tyre life and best overall
performance. Adjustments to wheel
alignment and tyre balancing are not
necessary on a regular basis. Consider
an alignment check if there is unusual
tyre wear or the vehicle is significantly
pulling to one side or the other. Some
slight pull to the left or right,
depending on the crown of the road
and/or other road surface variations
such as troughs or ruts, is normal.
If the vehicle is vibrating when driving
