What is tire road index?

Tire load index tells you how much weight your car can safely carry based on the correct tire size and pressure. It was calculated by the people who built your vehicle, and they know what they’re talking about!

What does load index mean?

Tire load index is an assigned number that corresponds to the maximum weight that a tire can support when properly inflated. The higher the tire’s load index number, the greater its load carrying capacity.

What does load index 101 mean?

1,819 pounds
Using an LT235/75R15 104/101S Load Range C tire as an example, the load index is 104/101. 104 corresponds to 1,984 pounds, and 101 corresponds to 1,819 pounds.

Is higher load index better?

6) Load index The higher the number, the higher the load it can safely handle. As an example, a tire with a load index of 89 can safely handle 1,279 pounds — while a tire with a load rating of 100 can safely handle as much as 1,764 pounds.

What’s better load range D or E?

Expert Reply: Load range D has a capacity of 1,220 lbs at 65 psi, whereas load range E has a capacity of 1,520 lbs at 80 psi. Basically the only difference between the two is the weight capacity.

What load index is 10 ply?

E”
However, the modern construction of tires uses fewer piles without sacrificing the carrying capacity. Therefore load range simply tells how tough the tire is and the allowable PSI. For example, an “E” load range indicates that a tire is equivalent to a 10-ply construction tire.

What is the 275 on tires?

The numbers in the tire size refer to its width, aspect ratio, and wheel diameter. “275/35R19″ means the tire is 275 mm wide, has an aspect ratio (that is, the width divided by the height) of 35%, and fits on a 19” wheel.

What is a good load index?

The higher the tire’s load index number, the greater its load carrying capacity. Choosing a tire with a lower load index than the original equipment specifications means that the tire will not carry the load capacity of the original. Most passenger-car tire load indexes range from 75 to 100, but some are higher.

Does load index affect ride quality?

Yes, tire load ratings do affect your ride’s performance, especially if you haul or tow materials, goods, boats, trailers, and so on. While tires are strong, the weight of your vehicle and whatever you’re towing puts extra pressure on them, which can cause premature wear or a blowout.

Should I get 10 ply tires?

Understanding the tire ply rating system helps you understand how your tires support the weight of your vehicle (called load range or load index). If you drive a ¾ ton, one ton or even larger pickup or SUV (or haul a trailer) then you require 10-ply tires.

Are all LT tires 10 ply?

LT tires are usually 8-ply (Load Range D) or 10-ply (Load Range E). Passenger Tires usually have a 4-ply or 6-ply equivalent sidewall. The performance trade-off of this added weight is a harsher ride, less fuel efficiency, and less responsive handling.

What does C1 mean on tires?

“C1” and “C2” are both 6 ply rated, but C1 has a max air pressure of 50 PSI and C2 has a max air pressure of 35 PSI. This holds true for other ply ratings too. Tires on a sedan, coupe, crossover or minivan are usually unmarked because they have a standard 4-ply rating and do not require higher load carrying abilities.
