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.
What does the load index on a tire mean?
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.
What is a 2500 load rating?
Match Your Tires’ Load Index For example, on a RAM 2500 a typical size would be an LT275/70R18 with a load index of 125 and a Load Range E.
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.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.
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.
Which speed rating is better H or T?
A T-rated tire can withstand top speeds of up to 118 mph (190 km/h), while an H-rated tire can support up to 130 mph (210 km/h). It is important to note these markings and stay within those speed limits.
Does tire load index affect ride?
Yes, tire load ratings do affect your ride’s performance, especially if you haul or tow materials, goods, boats, trailers, and so on. … It’s very important to check your tire’s air pressure regularly as the car tire load rating is only accurate when the tire is properly inflated.What load index is a 10 ply tire?

Article first time published onIs a higher ply tire better?
The more ply, the more sidewall strength. When your sidewall isn’t strong enough, the load squashes the tires down into the road. The tread then pushes into the ground and spreads out in a way that was never intended by the manufacturer, leading to a blowout.
Is Load Range E better than D?
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 is Load Index 121 on a tire?
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.
Should I put 10 ply tires on my truck?
Not just relegated to toilet paper, a tire’s “ply” is an older term referring to the internal layers of a tire’s construction. The more layers, the higher the load capacity (or the more weight it can support). … If you drive a ¾ ton, one ton or even larger pickup or SUV (or haul a trailer) then you require 10-ply tires.
What does C1 mean on a tire?
“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.
What does 123 120R mean on a tire?
The “123/120R” is the tire load rating in this section. These tires were created so they could be driven both on their own or in a dual wheel capacity. … The first rating of 123 means that if the tire was the only tire on that side, it could haul up to 3417lbs.
What does 98H mean on a tire?
Hurry Up and Weight The load index and speed ratings are grouped together, denoted, for example, as 98H. The load index is a number that generally ranges from 75 to 105; the higher the number, the more weight the tire can support. The speed rating is expressed with letters, and there are several.
What does 109s mean on a tire?
The numeric load index code 112 represents the maximum load carrying capacity for single wheel use and 109 represents maximum load carrying capacity for the dual wheel use. The first number 112 denotes a tire’s ability to carry approximately 2,470 lb (1120 kg).
What does 85T mean on tires?
MRF ZTX 165/80 R14 85T Specifications 85 is the load index i.e. the maximum weight each tyre can carry at full speed. T is the speed rating i.e. the maximum speed for the tyre at full load.
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.
What does 100 t mean on tires?
Just after the tire size are some more numbers, commonly 100T. The 100 is the tire’s load index, and in the case of 100, it means by itself a properly inflated tire can hold up 800 kilograms (1,764 lb.). … With each increase by one, such as 100 to 101, you would increase the load capacity of the tire by 25 kg (55 lb.).
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.
Can I fit 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.
Can I buy a tire with a higher load rating?
It’s ok to go with a tire that has a higher load rating than the original tires; just be careful to avoid tires with a lower load rating than specified for your vehicle, even if they are less expensive.
Are 12 ply tires good?

What is the difference between 8 and 10 ply tires?
The only difference is the max air pressure they’ll take. Usually a heavier load rating is accomplished through thicker plies, not more of them. Keep in mind though that the ply rating only pertains to the tread package, NOT the sidewall.
What's the difference between 14 ply and 16 ply tires?
Truck tires typically come in two load ratings: G and H. Load range G is a 14-ply configuration, while load range H tires have 16 plies. The heavier-rated tire will usually add between 700 pounds and 1,000 pounds more load-bearing capacity per tire (see “How Much is Too Much,” next page).
How important is load rating?
The load index of a tire tells you how much weight the tire can carry. The load index represents the tire’s toughness and ability to hold higher air pressures. …
Can load index be higher?
The higher the tire’s load index number, the greater its load carrying capacity. A tire with a higher load index than that of the Original Equipment (OE) tire indicates an increase in load capacity. A tire with a load index equal to that of the Original Equipment tire indicates an equivalent load capacity.
Whats better Load Range E or F?
F-load range tires allow for higher carrying capacity at a higher inflation pressure compared to tires of the same size with an E-load range. … “These new F-load range tires enable truck owners to get the tire performance and look they desire, while meeting or exceeding the load-carrying requirements of their trucks.”
What is Load Range E?
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.
