Load Range On Tires Mean

In the case of a tire with an 88 load index that tire would be able to support 1 235 pounds at maximum air pressure.

Load range on tires mean.

For example if a tire has a load index of 92 it can support 1 389 pounds at maximum air pressure. 94 indicates the load index. The first gives the speed rating while the next two indicate the load range. The tire load range is also known as ply rating a term that dates back to the days of bias ply tires which had different numbers of ply layers.

All tires are constructed of rubber and cord layers referred to as plies. The tire load index rating communicates how many pounds a tire can safely carry. Load range is based on an older measurement called ply rating. Light truck tires have two load indexes on the sidewall of the tire unlike passenger tires which only have one.

On some tires you may see three letters instead of one. Referring to the tire load rating index chart below the number 94 translates to a load carrying capacity of 1477 pounds per tire. They are actually terms from radically different historical eras that mean basically the same thing. Tires with a higher load range can carry heavier loads.

The load range ply rating branded on a tire s sidewall identifies how much load the tire is designed to carry at its industry specified pressure. The tire load index lets you know the load carrying capacity of a tire. In other words it s the amount of weight your tire can support safely. Passenger tires feature named load ranges while light truck tires use load ranges that ascend in alphabetical order letters further along in the.

For example an e load range indicates that a tire is equivalent to a 10 ply construction tire. In realitly this tire is not built with 10 plies but rather one or two plies of equivalent strength. Generally speaking the higher the tire load index the more weight the tire can safely carry. Tire load range vs.

Going back to the audi example the car s service information is. Historically more plies gave a tire a larger load carrying capacity so manufacturers would count the plies and use this number to denote carrying. Multiply that by four tires 4 x 1 389 5 556 pounds to get your car s maximum load carrying. This is because light truck tires are often used on vehicles with dual rear wheels.

Tire load range and tire ply rating. For example a light truck tire with a load index of 120 116 means a load capacity for a single tire of 3 086 pounds and a load capacity of 2 756 pounds for two tires. Maximum load ratings denoted in pounds or kilograms are also included on the sidewall of the tires. You may hear the terms tire load ranges and tire ply ratings tossed around together one which is designated by letters and one which is designated by numbers.

For example if you see 88s at the end of the tire size the load index would be 88. The higher the load index number the greater the tire s load carrying capacity. Current load indexes used for cars and light duty trucks range from 70 to 110 or 761 to 2337 pounds respectively.
