What does load index indicate?

The load index indicates the load-carrying capacity of a tire. In other words, it tells you how much weight your tire can support. … Multiply that by four tires (4 x 1,389 = 5,556 pounds) to get your car’s maximum load-carrying capacity.

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.

What does 121 load index mean?

Tire Load Index Capacity The rating of 121 shows that it has a load capacity of 3297LBS. Multiply that by four tires (4 x 3,297 = 13,188 pounds) to get your vehicle’s max load carrying capacity. Always remember to install tires that have a load index that is equal or greater than your original factory-installed tires.

Which speed rating is better H or T?

A speed rating of T indicates that the tire can be safely driven up to 118 mph. A tire with an H rating has a higher limit — 130 mph — which means it can be safely driven faster than the tire with the 94T code. … Tires with an H speed rating are often mounted on sport or sport sedan cars.

Does load index affect ride quality?

NO. Higher Load Index will only help you in carrying extra load. For a smoother ride on rough roads, drive carefully and keep the recommended inflation pressure.

Can I buy tires with a higher load index?

If you’re thinking about up-sizing, you can switch to a tire with a higher load index, because that means your tire can safely carry more weight, but you can never go down.

Is Load Range D better than C?

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. … For a C load range in the same size, like # AM1ST76 , the capacity is 1,360 pounds at 50 psi.

Can I use a TYRE with a higher load rating?

Is it possible to fit tyres with a higher load index and a lower speed rating than my manufacturer recommends? Yes, you can fit tyres that have a higher load index and a lower speed rating.

Does tire load index affect ride?

Does tire speed rating affect ride quality?

Speed Ratings Refer to More Than Just Speed Speed ratings affect more than just speed, they also contribute to ride comfort, wear, and cornering capabilities. In general, the higher the speed rating, the better the grip and stopping power, but the lower the tread life.

Does the speed rating on a tire matter?

The speed rating tells you the speed the tire can safely maintain over time. A higher speed rating usually means you will have better control and handling at higher speeds – and that the tire can take the extra heat. As a general rule, tires with higher speed ratings also handle better at slower speeds.

What are V rated tires?

SPEED RATING V Once the highest speed rating a tire could have, “V” used to represent a maximum of 149 mph (240 kph) or more. Nowadays, it means 149 mph but no higher.

Is a higher ply tire better?
