WHEELS
Your Boss302 is equipped with unique wheels matched to the tires.
These wheels are more susceptible to damage due to their diameter,
width and low profile tires. To avoid damage to your wheels:
•Maintain proper tire pressure (seeTiresin this supplement).
•Do not drive your vehicle through an automated, commercial car wash
due to the vehicle’s low ground clearance, tire width and track width.
Wash your vehicle by hand, or by using a touchless commercial wash
with no mechanical tracks on the floor.
•When installing wheels, always torque lug nuts to specification with a
torque wrench.
•Inspect your wheels for damage on a regular basis. If a wheel is
damaged, replace it immediately.
•In the event that you encounter an abnormally harsh impact, inspect
the outer edge of your wheels, both inside and out, for damage.
Operating at high speeds
Your Boss302 is capable of high speeds and is equipped with tires
rated for the vehicle’s maximum speed, electronically limited to 155 mph
(250 km/h). Remember to drive safely, obey all traffic laws and only
operate your vehicle at high speeds at locations equipped and designed
to do so safely. Before operating your vehicle at high speeds:
•Ensure correct tire pressures (seeTiresin this supplement).
•Inspect wheels and tires for wear and damage. Replace any damaged
wheels or tires.
•Do not operate your vehicle at high speeds with more than two
passengers or while carrying cargo.
Wheel lug nut torque specifications
Retighten the lug nuts to the specified torque at 500 miles (800 km)

high-performance, dry weather-only summer tires that provide
superior steering and handling.
WARNING:If equipped with the Laguna Seca Package, never
drive with these tires in any wet conditions (rain, snow, ice, etc.)
because they cannot channel water away and will slide risking serious
injury.
•Do not use tire chainson the original wheels and tires of your
vehicle. The use of any type of tire chain on these tires may damage
your vehicle.
•Always maintain your tire pressures according to the tire information
placard on the driver’s door jamb, using an accurate gauge.
•Tire pressures are specified “cold” and should be checked after the
vehicle has been parked for at least 3 hours. Do not reduce pressure
of warm tires.
•Check your tire pressure often to maintain it properly. Tire pressure
can diminish over time and fluctuate with temperature.
•Do not overload your vehicle. Maximum vehicle and axle weights are
listed on the tire information placard.
•Extra caution should be taken when operating the vehicle near its
maximum load, including assuring proper tire pressure and reducing
speeds.
•Extra caution should be taken when operating on rough roads to avoid
impacts that could cause tire damage.
•In the event that you encounter an abnormally harsh impact, inspect
your tires for damage.
•Inspect your tires for damage on a regular basis. If a tire is damaged,
replace it immediately.
