Precautions:<\/strong><\/p>\n\n\n\n

    \n
  • Check pressures when tyres are cold<\/strong> (vehicle not driven for 3+ hours).<\/li>\n\n\n\n
  • Underinflation = poor fuel economy, faster wear.<\/li>\n\n\n\n
  • Overinflation = reduced traction, uneven wear.<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    Heavy Load<\/td>300\u2013340 kPa<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Precautions:<\/strong><\/p>\n\n\n\n

      \n
    • Rear tyres may need higher pressure<\/strong> due to load distribution.<\/li>\n\n\n\n
    • Always adjust when carrying tools, cargo, or towing.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      Transport (Road Use)<\/td>160\u2013200 kPa<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

      Precautions:<\/strong><\/p>\n\n\n\n

        \n
      • Lower pressure in the field = better traction, reduced soil compaction.<\/li>\n\n\n\n
      • Inflate before transport to reduce tyre wear and overheating.<\/li>\n<\/ul>\n\n\n\n
        \n\n\n\n

        Precautions:<\/strong><\/p>\n\n\n\n

          \n
        • Dual rear tyres should be evenly inflated<\/strong>.<\/li>\n\n\n\n
        • Uneven pressure = poor stability and blowouts.<\/li>\n<\/ul>\n\n\n\n
          \n\n\n\n

          Precautions:<\/strong><\/p>\n\n\n\n

            \n
          • Use tyre pressure monitoring systems (TPMS)<\/strong> for large fleets.<\/li>\n\n\n\n
          • Pressure varies based on load, speed, and tyre ply rating.<\/li>\n<\/ul>\n\n\n\n
            \n\n\n\n

            \ud83d\ude9b 6. Trailers (Farm, Commercial)<\/strong><\/h3>\n\n\n\n

            Heavy Transport Trailer<\/td>500\u2013700 kPa<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

            Precautions:<\/strong><\/p>\n\n\n\n

              \n
            • Check trailer pressure before every trip<\/strong>.<\/li>\n\n\n\n
            • Ensure tyres are rated for the load and speed<\/strong> intended.<\/li>\n<\/ul>\n\n\n\n

              Precautions:<\/strong><\/p>\n\n\n\n

                \n
              • Adjust pressure to the attachment in use<\/strong> (e.g., bucket vs breaker).<\/li>\n\n\n\n
              • Daily inspection critical to avoid downtime or accidents<\/strong>.<\/li>\n<\/ul>\n\n\n\n

                \u2705 General Precautionary Measures for All Categories:<\/h3>\n\n\n\n
                  \n
                1. Check pressure at least once a week<\/strong> or before long hauls.<\/li>\n\n\n\n
                2. Use a reliable pressure gauge<\/strong>; digital is preferred.<\/li>\n\n\n\n
                3. Check valve stems<\/strong> for leaks or damage.<\/li>\n\n\n\n
                4. Monitor for bulges, cuts, or irregular wear<\/strong>.<\/li>\n\n\n\n
                5. Never “bleed” tyres after a long trip \u2014 hot tyres give false high readings.<\/li>\n\n\n\n
                6. Match the pressure to the load, speed rating, terrain<\/strong>, and season<\/strong>.<\/li>\n\n\n\n
                7. Always follow tyre ply rating and load index<\/strong> recommendations.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
