Likewise, Is Load Index 121 a 10-ply tire?
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. In realitly, this tire is not built with 10 plies, but rather one or two plies of equivalent strength.
Also, How much weight can an E rated tire carry?
The Load Range C BFGoodrich tire (manufactured by Michelin) is rated at 2,470 at 50 psi and weighs 44 pounds, while the same tire in Load Range E is rated at 3,195 pounds at 80 psi and weighs 52 pounds.

Moreover, What is load D on a tire?
A load range D tire has the same load capacity as a load range C tire if it is inflated to 50 psi and will provide the same ride characteristics. Load range D tires only provide more capacity and a harsher ride if they are inflated to the higher-rated design pressure.
What is Load Range D vs 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.
Will 10 ply tires last longer?
most 10 ply tires have a harder rubber compound and will last longer than a 6 ply tire.
What does 10 PR mean on a tire?
“Q” refers to the tire’s speed rating. In this case, the tire is rated at 99 mph for continuous use. The higher the letter, the faster the tire is rated to travel. 10 PR refers to the ply rating of the tire. A 10-ply rated tire is the same as a Load Range E tire.
Is Load Range D better than C?
Expert Reply: 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.
Which is better load range B or C?
A load range C tire will have a higher capacity than a load range B tire of the same size. … The Kenda 4.80-12 Bias Trailer Tire with 12 Inch White Wheel, # AM30580, has a capacity of 785 pounds at 60 psi and is a load range B.

Do 10 ply tires affect gas mileage?
It’s not just the weight of the tire but also the design of the tread. The weight of the tire is not going to make as big a difference as the tread design. If you went from a 4 ply to a 10 ply of an identical tire size and tread pattern you probably wouldn’t notice a difference in fuel economy.

What does the 70 r mean on a tire?
The number 235 is the cross-section width in millimeters, while 70 is the ratio of sidewall height to cross-section width (70 percent). R means radial-ply construction and 16 is the wheel diameter, in inches.
Can you mix D and R tires?
Expert Reply: It’s fine to use a radial-type tire as a spare (a tire with “r” in its size code) with a trailer that has Bias ply “d” tires but for a short distance in the event of a flat tire. But mixing tires is not recommended for everyday use because their internal construction is different.
What are the three types of tire construction?
There are three main types: clincher, wired and tubular. Most bicycle tires are clincher and have a bead that presses against the wheel rim. An inner tube provides the air pressure and the contact pressure between bead and wheel rim.
