Tire safety and maintenance checklist:
• 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 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.
• When towing your trailer, remember that part of the trailer's
weight is transferred to the tow vehicle.
Practical tips regarding tires:
• Make sure all wheel lug nuts are securely tightened. Use a torque
wrench.
• This is the only way to ensure the nuts are tightened.
• Inspect tires for uneven wear patterns on the tread, cracks,
foreign objects, or other signs of wear or trauma.
• If you are towing a trailer, remember that part of the trailer's
weight is transferred to the tow vehicle.
• A trailer's hub bearings must be greased after a long storage
period.
