The 115T signifies that the tire has a 4ply standard load sidewall. The 121S signifies a 10 ply load range E sidewall. The standard load tire is best for a half ton truck, whereas the load range E sidewall is best for a 3/4 and 1 ton truck.
What load range is 115?
Higher load index ratings mean your tires will be able to handle a heavier load. In this example, there are two numbers.

What is a load range T?
The load range indicates the heaviest load the tire can handle in pounds. Maximum tire pressure indicates the highest you can inflate the tires, but do not fill your tires to this pressure. It reflects the highest pressure the tire can handle when carrying its maximum load.
Is 116T a 10 ply tire?
116T is a 4ply normally used on 1/2 ton applications.
What does 115T mean on a tire? – Related Questions
What does 116T mean on a truck tire?
In the case of the number 116, it corresponds to an industry code (from 70 to 126, 116 meaning 2535 lb or 1150 kg), while the letter T tells us that the tire can safely withstand a sustained maximum speed of 118 mph or 190 km/h.
What are T tires rated for?
SPEED RATING T
With a maximum speed of 118 mph, you usually find tires with speed rating “T” on family sedans and minivans.

How do you tell if a tire is a 10 ply tire?
Plies – “E”
The last letter in a standard tire size indicates the number of layers used in the construction of the tire. If there is no letter, the tire has the standard 4 plies. A “C” indicates 6 plies, a “D” indicates 8 plies, and an “E” indicates 10 plies.

What load range is a 10 ply tire?
Load Range E tires are equivalent to a 10-ply tire.
Is 10 ply tires good for truck?
10-ply tires are typically available for heavy-duty trucks or trailers. It tends to carry heavy materials daily and is more sustainable than conventional tires. Having this trait, since 10-ply tires can take loads more often than not, they are also better off-road, especially for climbing purposes.
Is a higher ply tire better?
PLY RATING
This number correlates to the maximum safe carrying capacity of the tire when it’s inflated to its maximum pressure. Higher load index ratings mean your tires may be able to handle a heavier load.
Is 10 Ply Load Range E?
Yes, all load range E tires are 10 ply. This is because load range is determined by the number of plies the tire’s construction has.
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.
How much weight can a 10 ply trailer tire carry?
Tire Weight / Tire Pressure = Load Capacity Pounds per PSI
At 80psi, a 265/75R16 10ply itire will carry 3,085 pounds of load. At 60 psi on a 10ply tire, the tire’s load carrying capacity is reduced to 2,314 pounds per tire. If the customer runs 65 psi in a 10 ply tire, his capacity is now able to carry 2,507 per tire.
Are load range E tires good for towing?
At a minimum, Load Range E tires are capable of safely supporting about 3,000 pounds. So, in the case of a dualie (six wheels), the tires collectively will provide more than sufficient grip for safely towing 18,000 pounds.
Why are truck tires not allowed on trailers?
The dangers. When a car or truck tire is used on a trailer, it causes stress that the tire wasn’t designed to handle. The tread of the tire begins wearing differently than it was designed. The tire’s actual weight capacity is different from the load rating shown because of the different frame designs.
What is the best load range tire for a trailer?
C load range tires are suitable for many types of trailers. With a tire pressure of 50 psi, a C range tire with a diameter of 14” can support a load of about 1,700 pounds per tire.
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.
Does tire ply matter?
The ply rating translates in a very direct way to tire capabilities and limitations, especially when it comes to inflation and load capacity. If you plan to haul, tow, or carry heavy loads with your vehicle, then understanding the ply rating of your tires is a must.
