Section 2
Identification and Safety
Because tires are designed to be used on more than one type of vehicle, tire manufacturers list the
maximum permissible inflation pressure’ on the sidewall. Your Aviator tires are ST225/75R15D tires and
the pressure should be maintained at 65 PSI or 448 kPa.
It is important to check your vehicle’s tire pressure at least once a month for the following reasons:
• Most tires naturally lose air pressure over time.
• Tires can lose air suddenly if you drive over a pothole or strike the curb when parking.
• With radial tires it is usually not possible to determine under inflation by visual inspection.
For your convenience, purchase a good quality tire pressure gauge to keep in your vehicle.
Preventing Tire Damage
• Slow down if you have to go over a pothole or other object in the road.
• Do not run over foreign objects in the roadway, and try not to strike the curb when parking.
• Check tire pressure regularly (at least once a month), including the spare.
• Inspect tires for uneven wear patterns on the tread, cracks, foreign objects, or other signs of wear
or trauma.
• Remove bits of glass and any other foreign objects wedged in the tread.
• Make sure your tire valves have valve caps.
• Check tire pressure before going on a long trip.
• Do not overload your vehicle. Check the tire information placard for the maximum recommended
load for the vehicle.
• If you are towing a trailer, remember that some of the weight of the loaded trailer is transferred to
the towing vehicle.
Federal law requires tire manufacturers to place standardized information on the sidewall of all tires.
This information identifies and describes the fundamental characteristics of the tire and also provides
a tire identification number for safety standard certification and in case of a recall.
MAINTENANCE TIP:
When a trailer is being stored for a prolonged period of time, follow the tips listed below to help
prolong the life of your tires.
• Keep the tires inflated with the correct air pressure in each tire.
• Protect your tires from the elements by keeping them covered.
