Tire Inflation Pressure
Guidelines
Tire inflation pressures affect vehicle
handling and tire life, and should be
adjusted for various types of tracks/
courses.
Inspect the tires prior to every track/
course session. Track/course driving
will reduce the tire tread life.
To maximize tire life, drive 800 km
(500 mi) prior to racetrack driving or
complete the minimum track running
that will increase the tire pressures by
35 kPa (5 psi). After this, immediately
let the tires cool to cold pressures.
Tire Inflation Pressure High Speed
See Tire Pressure for High-Speed
Operation 0371.
Tire Inflation Pressure for Track
Driving
For driving on a race course, if your
vehicle is equipped with 255/35ZR18
(94Y) and 275/35ZR18 (99Y) tires, set
cold (stationary) tire pressures to
30 psi. During track sessions, set the pressures at 35 to 38 psi for hot tire
pressures. If pressures exceed 38 psi,
bleed pressures down to 35 to 38 psi.
Return the tires to the recommended
cold tire inflation pressure when track
driving has ended.
Driving and Operating
{Warning
Operating the vehicle at high speeds
can be dangerous. Improper tire
inflation pressure can put
additional strain on the tires and
can cause a sudden failure. Make
sure the tires are in excellent
condition, and use the correct cold
tire inflation pressure for the
vehicle load and track/course.
{Warning
Tracks/courses put high loads on
tires operating at high speed, which
can lead to tire failure if not
inflated properly. Always limit
vehicle cargo to the driver plus one
passenger with no additional cargo.
