Saturn 2008 Aura - Manual (Page 316)

{ CAUTION:
If you use bias-ply tires on the 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 the 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 could 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 5-59.
Your vehicle’s original equipment tires are listed
on the Tire and Loading Information Label.
See Loading the Vehicle on page 4-24, for more
information about the Tire and Loading Information
Label and its location on your vehicle.
