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.
Warning
Track/course loads wear tires both on the
tread and internal to the tire. When
driven in track/course conditions, even if
tread is not worn down to the treadwear
indicator, tires must be replaced after the
equivalent of two tanks of fuel or
approximately 160 km (100 mi).
