In other words, it’s the amount of weight your tire can support safely. For example, if a tire has a load index of 92, it can support 1,389 pounds at maximum air pressure. As the load range letters move closer to "Z," the amount of weight the tire will withstand increases. Load Range Tire Pressures Recommended tire pressure increases as the tire load range moves higher. Definition of Tire Speed Ratings. A tire's speed rating is an indication, expressed as a letter code on the tire sidewall, of a speed the manufacturer expects the tire to be able to sustain over a long period of time without coming apart. This is good information to have for a number of reasons, some of which actually include the likelihood

## Letters ranging from A to Z represent the speed rating. Each letter denotes the maximum speed a tyre can sustain under its recommended load capacity.

The tire’s Service Description code is to the left of the Load Range: Load Index (199 = 2,998 pounds) and Speed Rating (Q = 99 mph). Load Range: LT-Metric Vs. LT-Flotation Vs. 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. Light Truck Tires (LT) designate ranges in ascending alphabetical order, with load range ‘B’ representing a 4-ply rating at 35 PSI; C representing a 6-ply rating at 50 PSI, and so on. As you can see, the further down the alphabet you go, the strong the tire will be. It’s usually one or two letters, or a letter and a number.

### The LOAD INDEX is a numerical code associated with the maximum load a tyre can carry (except for loads at speeds above 130 mph (210 km/h) – see Table 2/ 2a)

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. For example, if a tire has a load index of 92, it can support 1,389 pounds at maximum air pressure. Multiply that by four tires (4 x 1,389 = 5,556 pounds) to get your car’s maximum load carrying There are letters on the tire's sidewall that correspond with "tire load range," historically known as the "tire ply rating." Load range and ply rating specifically refer to how much load your tire can support at maximum allowable air pressure. The load range is identified by a letter of the alphabet, usually from A to F, which represents the ply rating and load pressure. A rating of "E" on the tire means the tire has a ply rating 10 and a load pressure of 80 psi. The tire’s Service Description code is to the left of the Load Range: Load Index (199 = 2,998 pounds) and Speed Rating (Q = 99 mph). Load Range: LT-Metric Vs. LT-Flotation Vs. 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.
