Cadillac 2006 EXT Automobile User Manual


 
High Speed Operation
{CAUTION:
Driving at high speeds, 100 mph (160 km/h) 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.
If your vehicle has P265/70R17 AL2 size tires and you
will be driving at high speeds, speeds of 100 mph
(160 km/h) or higher, set the cold inflation pressure to
the maximum inflation pressure shown on the tire
sidewall, or 38 psi (265 kPa), whichever is lower.
See the example following. When you end this
high-speed driving, return the tires to the cold inflation
pressure shown on the Tire and Loading Information
label. See Loading Your Vehicle on page 4-44.
Example:
You will find the maximum load and inflation pressure
molded on the tire’s sidewall, in small letters, near
the rim flange. It will read something like this: Maximum
load 690 kg (1521 lbs) 300 kPa (44 psi) Max. Press.
For this example, you would set the inflation pressure
for high-speed driving at 38 psi (265 kPa).
