Tire Inflation Pressure for
Track Driving
For driving on a race course,
if the vehicle is equipped with
275/35ZR19 (100Y) and
305/30ZR19 (102Y) tires, set
the cold (stationary) tire
pressures to 28 psi. During
track sessions, set the tire
pressures at 35 to 38 psi for
hot tires. If pressures exceed
38 psi, adjust the 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 (Continued)
Warning (Continued)
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(Continued)
