  • Tyre knowledge required.

    I need a couple of tyres for my towed cherrypicker.They are 16" and at the moment one is badly cracked and both are the wrong tyre for the application in that the thing weighs two tonnes and the load ratings of these tyres is less than that.
    It`s single axle,single wheels.
    Not a problem for about the yard but I need it at home for a few jobs.
    I`ve been having a nose about but can`t seem to find a lot of info on load ratings if you don`t have a vehicle type.
    I was thinking about 750 x 16 but don`t mind being corrected.

      In the image above shows the location of the important information, going by what you posted your weight requires that a number in excess of 108 needs to be used (single tyre loading )
      108 = 1000kg 109 = 1030kg 110 = 1060kg 111 = 1090kg
      112 = 1120kg 113 = 1150kg 114 = 1180kg 115 = 1215kg
      116 = 1250kg
      117 = 1285kg 118 = 1320kg 119 = 1360kg
      60 97
      69 111
      75 120
      81 130
      87 140
      The letter are speeds bands.

      Now a 750 X 16 is tyre height 7.5" wide, by 7.5 + 16 + 7.5 = 31" . Standard langer rodent tyre.

      but a 235 x 85 x 16 might be better or a 205 might be lower........................

      235 x 85 x 16 breaks down as follows

      235 width of tyre in mm ............

      85 = Height ( % of width )

      16" = rim size...

      So a tyre of 235mm wide with an 85% height is 235 x .85 = 199.75 this is doubled 399.5 + 16 (convert to mm = 406.4mm)

      399.5 + 406.4mm = 805.6mm convert to inches 31.7"........................

        Here's a little more info for you. http://www.tirerack.com/tires/tirete....jsp?techid=55 It kind of rehashes some of what each Stock and Ian gave you. I know there are higher load range designations for the sizes that fit this category, the highest load rating tire I have ever seen is a "G" rated tire for house trailers. Keep in mind these letter designations should not be confused with the speed rating. It will very clearly state on the tire "Load Range E" or what ever range it fits. Most passenger car tires that have no rating are assumed to be load range "C."

            Yep.The trouble is if you don`t know what the load number codes mean you don`t know what to look for.
            You can spend all day looking at the sizes of tyre you think you need but if it doesn`t say "max load XXXX" you`re f`ked.
            But,the chart that Stock posted has the needed info.
