It is possible to determine the tire load capacity through load index, ply rating, and load range. The amount of weight that your tire can carry can be determined by the amount of air it can hold. Therefore, if you want to achieve a higher tire loading capacity, the tire needs to have more air and maintain more pressure, more air volume, and it should be strong enough.

When you look at the tire load rating chart, it can be very helpful for you to make sure that you have the right tire loading capacity after consulting the suggestion of the original equipment tire manufacturers. The radial construction and the steel ply materials keep improving, thus making the ply rating number less effective in determining the loading capacity of the tire. A load rating chart is a guide to provide the load-carrying capacity of your vehicle accurately.

The importance of the tire load index chart

When your vehicle tires are overloaded, there is quite a possibility that a disaster can strike as a result of gradual damage. You may even have a completely flat tire in the middle of the road. You can think of it as if someone gives you a cardboard box and then starts to fill it with bricks. Your legs will surely begin to buckle under the weight at some point, and the bottom of the box will inevitably break.

When there’s too much weight put on your tires, then it is likely that they may wear down prematurely, or they may even give out fully. Therefore, it is always recommended not to risk it and not to overload your tires.

How to use the load rating chart?

The tire load rating chart can be very helpful for you to discover your tire's load-carrying capacity or the amount of weight that it can support safely. Suppose you have a load index of 84; by using a chart, you can know that the tire can support 1,102 pounds when it is at the maximum air pressure. If you would like to find out the maximum loading capacity of the car, you have to multiply that by four times. Here’s a good example.

It is always recommended not to go for tires with a lower carrying capacity than the one suggested in the chart. There will be a good tire load rating with the factory-installed tires that happen to come on your car. So, if you like to swap these tires out, you have to stick to the same number or a higher one.

Summary

The tire load rating chart tells the amount of weight that can be carried safely by your car based on the correct size and pressure of the tire. This chart is calculated by the experts who built the vehicles, so they know what they are talking about.

If you want to find out the recommended load rating and tire size, you always have the option to check the owner’s manual or check those tires that came with your car when you bought it. You always have to stick to the same or the higher number when purchasing new tires.
