Load Rating & Speed Rating

Trying to work out the speed and load rating of tyres can be quite confusing but using the chart below, we’ve made it very simple for you to work out. The load rating is always in numbers and the weight shown is per tyre, so you will need to add up all four tyres load rating to get the complete weight limit for the tractor. The speed rating is shown with letters and shows the maximum speed recommended for this tyre when the tyre is at nominal pressure.
