Cadillac 2007 Escalade EXT Owner's Manual page 471

CAUTION:
{
If you use bias-ply tires on your vehicle,
the wheel rim flanges could develop
cracks after many miles of driving. A tire
and/or wheel could fail suddenly, causing
a crash. Use only radial-ply tires with the
wheels on your vehicle.
If you must replace your vehicle's tires with those
that do not have a TPC Spec number, make
sure they are the same size, load range, speed
rating, and construction type (radial and
bias-belted tires) as your vehicle's original tires.
Vehicles that have a tire pressure monitoring
system may give an inaccurate low-pressure
warning if non-TPC spec rated tires are installed
on your vehicle. Non-TPC Spec rated tires
may give a low-pressure warning that is higher or
lower than the proper warning level you would
get with TPC Spec rated tires. See Tire Pressure
Monitor System on page 462.
Your vehicle's original equipment tires are listed
on the Tire and Loading Information Label.
This label is attached to the vehicle's center pillar
(B-pillar). See Loading Your Vehicle on page 372,
for more information about the Tire and Loading
Information Label and its location on your vehicle.
