  • Page 225: Tyres

    PREVENTIVE MAINTENANCE TYRES TYRE INFLATION AND LOADING Regular and frequent inspection, and proper care will give you the assurance of safe, reliable tyre operation. Most tyre wear problems are caused by under inflation as the result of slow leaks. Low pressure is the tyres worst enemy; it allows tyres to flex badly and this causes high temperatures to build up.

  • Page 226: Tyre Inflation

    PREVENTIVE MAINTENANCE TYRE INFLATION Most tyre wear problems are caused by underinflation. So you will want to check tyre pressure regularly. Give the tyres a visual test every day and check inflation with a gauge every week. When checking tyre pressure, inspect each tyre for damage to sidewalls, cuts, cracks, uneven wear, rocks between dual wheels (tyres) etc.
  • Page 227 PREVENTIVE MAINTENANCE It is also important to regularly have a wheel alignment: • Too much air pressure reduces the tyre tread contact area and results in rapid wear in the centre of the tyre. It also causes tyres to run hard and makes them more vulnerable to impact and other road hazard damage.

  • Page 228: Maximum Vehicle Load Rating

    PREVENTIVE MAINTENANCE Overinflated tyres can cause accidents. They wear more quickly than properly inflated tyres and are more subject to punctures, cracks and other damage. They could fail and cause you to lose control of your vehicle resulting in an injury and/or accident. Be sure all tyres are inflated correctly according to the manufacturer’s recommendations.

  • Page 229: Replacing Tyres

    MATCHING TYRES In addition to having tyres balanced, and having their radial and lateral run-out checked, we recommend that you have an authorised Kenworth dealer match your tyres, particularly on the rear axles. Mismatched tyres can cause interaxle conflict and unusually high axle lubricant temperatures.

  • Page 230: Wheel Cap Nut Torque

    At the first scheduled lube interval, have all wheel nuts torqued to their specified value. Thereafter, wheel nuts MUST be checked at least once a week. Contact the service department at any authorised Kenworth dealership for information on torque values applicable to the wheels installed on your truck or see the table below.

  • Page 231: Vehicle Jacking

    PREVENTIVE MAINTENANCE VEHICLE JACKING Ordinary pedestal jacks are designed ONLY to LIFT a vehicle. Once lifted, the vehicle should be supported by other appropriate means, such as stands.
