What is load range D on trailer tires?
It is one of the trailer tires built with diagonal or crisscrossed plies to support a weight of up to 1,220 pounds. On average, the tire can withstand a weight between 1,200 to 1,220 pounds.
However, it depends on other factors like the pressure capacity and the nature of the road. At 65 psi, each tire can comfortably withstand the weight of that range. However, if your tire is 11.5 inches in diameter, it is not advisable to exceed 1,220 pounds per tire.
The bigger ones can support as many as 2,500 without any issues. The bias-constructed tires are ideal for moving heavy haulage and make them best for use in a trailer.
What is the ply rating on load range D trailer tire?
It refers to the number of rubber layers used to construct the tire. Each tire range has a unique quantity as part of its components.
Load range D trailer tires have a ply rating of 8 and correlate to the maximum and safe carrying capacity. However, it must have maximum pressure for optimal performance.
As the ply ratings per tire increase, so does the weight capacity. The load range E tire should accommodate more weight than D because its ply rating is 10. On the other hand, a C-rated tire supports less weight because its ply rating is at 6.
How much weight can Load range D tire support?
At a maximum pressure of 65 psi, load range D tire can support a load of up to 1,220 pounds. However, the load range can vary depending on the pressure in the tire at any given time. It is not advisable to inflate the tire to maximum pressure as it might cause instability when driving the trailer.
It will produce a lot of vibrations, especially at high speeds. Load range D tire is in into two in terms of size and pressure rating. The maximum load pressure, if it is less than 295mm or 11.5’’ wide, should be 50 psi.
Essentially, this means less weight haulage. On the other hand, if it is more than 295mm or 11.5’’ wide, the pressure capacity should be at 65 psi. It can, therefore, support more weight, but it should not exceed 1,220 pounds per tire.
Is load range D better than C?
That would be the case in several aspects. The progression schedule of these trailer tires indicates that as you scale the ladder, the tire gets best.
Load range C tires have inferior features to C, with the size as the only similarity. Most of the trailer tires have the same size. It is not easy to differentiate between them, going by this feature, until you read through the specifications on the sidewall.
Load range D tire has a higher ply, pressure, and weight rating than C. It also saves on transportation costs by moving large volumes of cargo. Load range D tire is also long-lasting than C because it has a high number of rubber plies inside it.
What is the difference between load range D and C tires?
There are a few differences between load ranges D and C tires. The Psi and capacity ratings are the most common differentiating factors. The size and other dimensions are similar and even fit on the same wheel. However, the D-rated tire has a higher capacity than C.
- C has a ply rating of 6, while D has 8.
- C has a psi rating of 50, while D is 65.
If you are to select between D and C tires, I would advise you to go for the first one because of the many merits it offers. It also has a longer useful life than C .
What is pressure capacity of load range D trailer tire?
When you understand what is load range D on trailer tires, it becomes easier to implement its uses. Among them is the pressure capacity. The recommended specification is 65 psi., or 450 kpa., at maximum. However, do not inflate the tire to maximum capacity because it may blow up or cause instabilities.
The maximum load pressure at less than 295mm or 11.5’’ wide, pressure capacity should be at 50 psi. On the other hand, if it is more than 295mm or 11.5’’ wide, the recommendation is 65 psi.
Comparison between load range D tires and car tires
There are several distinguishing features between load range D trailer tires and car models. They include the following:
| Detail | Load range D trailer tires | Car tires |
| Wheel design | Radial ply and bias | Radial ply |
| Ply ratings | 8 and more | 6 and below |
| Psi ratings | 65 | 50 |
| Tire ratings | ST and TL | TL and P-metric. |
Other factors, such as tire size, remain constant, and they can fit in one wheel. Load range D tire is also long-lasting. Car tires have thinner sidewalls and low ply ratings because they carry less weight, which makes them ideal for fast movement.
Benefits of using load range D trailer tires
Load range D trailer tires are some of the most resilient products on the market. Some of the key benefits of having one include the following:
- It can haul large cargo at once, saving on transportation costs.
- Long lasting because it has a high number of ply ratings.
- It has a high-speed rating of 65 mph.
- It has a high carrying capacity of 1,220 pounds per tire.
- It has excellent grip and control construction making it ideal for use even in harsh weather and snowy conditions.
- It is stable when driving on all types of roads

Frequently asked questions.
What is the maximum capacity on load range D trailer tire?
Load range D trailer tire can hold a weight of up to 1,220 pounds per tire. The pressure capacity at such conditions should be 65 psi.
If the pressure capacity is at 50 psi, the weight it can support will be less than 1,220 pounds per tire. Experts do not recommend inflating the tire to the maximum as it can cause some effects in the short run.
What is the ply rating on the load range D trailer tire?
Load range D trailer tire has a ply rating of 8. It refers to the number of rubber layers used to construct the tire. The more the number, the higher the weight it can move.
The progression schedule of trailer tires indicates that the ply ratings increase on a range of two from the low to high-rated tire. C has low amount of ply than F.
What is the speed rating of the range D trailer?
Load range D trailer tire has a speed rating of 65 mph at either 50 psi., or 65 psi. On roads that are not the best, speed reduces significantly.
Poor weather also impacts the speed rating of a trailer tire.
The tire, however, has a speed rating because of its excellent performance, even on bad roads.
