Tire care Checking Tire Pressure Note: Underinflated tires can decrease handling, stopping performance, traction, tire life, and load-carrying capability, in addition to causing other negative and hazardous effects, including tire failure. Overinflated tires are at greater risk of an impact break, where the tread and casing break when striking a hard edge, often opening a huge gash across the tread. Incorrect inflation pressure also increases tires wear rate.
6. Check all the tires to make sure they have the same air pressure. 7. If the tires’ pressure was not measured “cold”, then the pressure should be rechecked with the tires cold as soon as possible. Tire Size To maintain safety, only purchase new tires of the same size as the original tires. Look at the Tire and Loading Information Placard, the Specifications Chart in this manual, or the sidewall of the tire being replaced. If you have any doubt about selecting the correct size, consult a tire dealer.
Vehicle Load Limit Steps for Determining Correct Load Limit 1. Locate the statement “The weight of cargo should never exceed XXX pounds” on your vehicle’s placard. 2. That figure equals the available amount of cargo and luggage load capacity. 3. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity. 4.
INSPECTION, MAINTENANCE, AND CLEANING 1. The following Chart serves as a basic guideline for scheduling your trailer maintenance. Maintenance may be different based on your local conditions, type of trailer, and frequency of trailer use. 2. CAUTION! All maintenance, service, or repairs listed in this manual are only to be attempted by a qualified service technician.
