What is the load speed rating tires?

The tire speed rating is the maximum speed tires can safely carry a load (the original weight of your vehicle plus whatever’s in it) for a sustained amount of time in ideal conditions. The rating is molded on the tire sidewall, signified by a letter or two, usually after the load index number.

What is load speed index?

The load index indicates how much weight a tire can safely carry at maximum air pressure, and the speed rating represents the maximum operating speed.

Is a higher load rating better?

Usually considered in combination with a tyre’s speed index, the rule of thumb is that tyres with a higher load index number are capable of carrying a heavier load capacity than those with a lower number. This can be compounded even further where the tyre pressure is incorrect.

What does 102 h mean on a tire?

102T and 102H are service descriptions. 102 is the Load Index, what this means is, the tire is capable of carrying weight up to, 1,874 lbs per tire. The T and H are speed Ratings, this indicates that a tire is capable of speeds up to, 118 mph and 130 mph (respectively). 102T and 102H are service descriptions.

What does 120 load index mean on tires?

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. The reason the capacity for two tires is lower than a single tire is to make sure that the vehicle can continue to carry the load should one tire fail.

What load rating do I need?

To roughly determine the load range capacity for each individual tire, take the vehicle’s gross weight and divide by four. If the vehicle gross weight is 4,500 pounds, each tire should be able to safely support at least 1,125 pounds.

Can I buy tires with a higher load index?

The tire’s grip, cornering ability, ride comfort, and wear durability, are all taken into account when determining a wheel’s speed rating. As such, as the speed rating increases so do the tire’s grip and cornering abilities. At the same time, the tire’s tread life will decrease.

What is 99H on a tire?

235/55R17 99H- The load index (99) is the tire size’s assigned numerical value used to compare relative load carrying capabilities. The higher the tire’s load index number, the greater its load carrying capacity. Typically, the load indexes of the tires used on passenger cars and light trucks range from 70 to 110.
