Load Ratings |
|
Load Ratings are one of the most important aspects to consider on any type of vehicle. The Ancestor of the modern load rating was the Ply Count; the ply count was used to determine a safe working load based on the number of nylon plies (often referred to as Bias, Rags or Crossply type tyres) that were utilised in the construction of tyres. Nylon Tyres and Ply Counts are still used in Military Vehicles, Farm Equipment, Mining Equipment and Garden Equipment, but are strictly prohibited from use on Australian Roads.
The Modern Load Rating System is very well designed and simple in principle with a given number stamped on the sidewall of the tyre (sometimes 2 numbers in the case of Truck Tyres, Commercial Tyres and Light Truck Tyres) to indicate its tolerance when dealing with a given load. |

How Do I Find My Load Rating? |
|
Most tyres use modern style load ratings, and whether the tyre is Metric, Imperial, or Truck Type Sizing the Load Rating will be in roughly the same spot after the tyre size - the Load Rating Location is shown in Orange below. |

Why Are There Two Load Ratings On My Tyre? |
|
2 Load Ratings more commonly known as Dual Load Rating refer to a tyre's ability to 'bag out' while still maintainin adequate structural integrity in motion. Dual Load Ratings refer to the point where a tyre can maintainits shape with minimal bagging against the road surface. The main issue with the bagging at this point is not the tyre's structural integrity but the liklihood that it will come into contact with the tyre placed next to it in a dual wheel situation during the bag out. |

|
In a Steer Position Situation the Tyre is free to 'bag out' to its maximum load rating as there is free space on both sides for it to safely do so. |
|
In a Rear Dual/Dual Position Situation the Tyre cannot 'bag out' to its maximum load rating as the second tyre would come into contact with it, creating friction and jeopardizing the tyre's structral integrity. |
