Cadillac 2010 DTS - Manual (Page 376)

Professional Vehicle
The proper inflation of the tires on your
professional vehicle depends on the type of tires
on it.
• If your vehicle has P235/60R17 size tires, the
cold inflation pressure is 41 psi (284 kPa).
• If your vehicle has LT235/60R17E size tires,
the cold inflation pressure depends on the
vehicle mass and should be determined by the
vehicle coach-builder. A Tire and Loading
Information label provided by the final stage
manufacturer should be attached to the B-pillar
on the driver’s side of the vehicle. If the final
stage manufacturer’s label is not present,
the coach-builder should be consulted. Do not
use the tire pressures indicated on the
General Motors label. These tire pressures are
for the incomplete vehicle and are not the
correct tire pressures for the completed
professional vehicle.
Operation at inflation pressures below this
recommendation may cause your tires to become
overloaded.
High-Speed Operation
{ WARNING:
Driving at high speeds, 160 km/h (100 mph) or
higher, puts an additional strain on tires. Sustained
high-speed driving causes excessive heat build up
and can cause sudden tire failure. You could have
a crash and you or others could be killed. Some
high-speed rated tires require inflation pressure
adjustment for high speed operation. When speed
limits and road conditions are such that a vehicle
can be driven at high speeds, make sure the tires
are rated for high speed operation, in excellent
condition, and set to the correct cold tire inflation
pressure for the vehicle load.
