What does ST175 80R13 mean?
Tires beginning with a ST (for example ST175/80R13) indicate a Special Trailer tire and should only be used on car, boat or utility trailers. LOAD INDEX AND SPEED RATING. Example: P225/60/R16 94V. The load index and speed rating, or service description, are the numbers that follow the tire size. ST stands for “special trailer tire. P or LT stands for “passenger” or “light truck” tire. Because of an ST tire’s heavier design, it is designated to carry more load than a P or LT tire. Tread patterns between the two are also specific to their applications. STs have an equal volume of air space.LT stands for Light Truck, a tyre compatible with 4×4 vehicles and light trucks and can carry and tow heavy loads. LT stands for Light Truck, a tyre compatible with 4×4 vehicles and light trucks and can carry and tow heavy loads. ST stands for Special Trailer, a tyre used by trailers for travel, utility, and boats.Special Trailer (ST) tires are purpose-built for trailer axle applications, catering to the specific demands of towing without consideration for passenger comfort. Unlike Light Truck (LT) tires, ST tires are engineered to endure heavy loads while being towed behind vehicles.ST rated tires have stronger sidewalls with the majority of the casing plies located there to support the load that’s directly pushing down on them. LT tires have the plies located more on the tread to take the forces of braking, cornering, and traction when taking off.Special Trailer (ST) tires are purpose-built for trailer axle applications, catering to the specific demands of towing without consideration for passenger comfort. Unlike Light Truck (LT) tires, ST tires are engineered to endure heavy loads while being towed behind vehicles.
What is the difference between ST175 80R13 and ST185 80R13?
In terms of size they are very close to one another; the ST175/80R13 size measures 24. ST185/80D13 size measures 24. Both tire sizes fit on the same wheel sizes, 13-inchers that are 4-1/2, 5 or 5-1/2-inches wide. The 175/80 R13 tyre size means a width of 175mm, an aspect ratio of 80%, and a 13-inch rim. A staple for first-generation small cars, it supports economical driving. Common on compact vehicles like the Chevrolet Matiz, Daihatsu Cuore, and Fiat Seicento.R13 tires have a diameter of 24 (610 mm), a tread width of 6. The sidewall of the tire is 5.This number represents the width of the tyre in millimeters from sidewall to sidewall. In this case, the tyre is 175 millimeters wide.R13 tires have a diameter of 24 (610 mm), a tread width of 6. The sidewall of the tire is 5.
What is the difference between 75D and 75R tires?
The D in a tire size of ST205/75D15 stands for bias ply and if you see the letter R in the tire size where the D is, that is a Radial tire. R: Signifies radial construction, which is prevalent in trailer tires for its durability and stability.R” indicates that the tire is a Radial tire and “D” designates that it is a Diagonal (also known as “Bias”) ply tire and “B” means it is a Belted-Bias ply tire.D tires are typically rated for a higher load capacity, making them ideal for heavy-duty trailers that carry substantial weight. On the other hand, R tires are generally designed for lighter loads and provide a smoother ride, which can be beneficial for recreational trailers.Yes, you can run a 175/80-R13 tire on a trailer that came with a 175/80-D13 tire. The only difference between the two is that R stands for radial ply and D stands for diagonal.You may also find tires with the letter “D”, which stands for Diagonal or Bias-Ply. We will explore tire construction later in this article. The last digit will represent the wheel size that the tire will fit represented in inches. For this tire, it will fit trailer wheels measuring 15 inches in diameter.
What is the difference between ST175 80R13 and d13?
The D in 175/80D-13 indicates that it is a bias ply tire where as the R in 175/80r-13 indicates that it is a radial tire. The difference is how the steel belts inside are oriented. Bias ply tires are generally better in off road types of situations. Radial tires track better and run cooler. 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.Common Ply Ratings: 6-ply tires: Light-duty tires for smaller trailers. Suitable for medium-duty trailers and small RVs. Standard for heavy-duty trailers, utility trailers, and some RVs.D tires are typically rated for a higher load capacity, making them ideal for heavy-duty trailers that carry substantial weight. On the other hand, R tires are generally designed for lighter loads and provide a smoother ride, which can be beneficial for recreational trailers.Load Range C: 6-ply rating, a common choice for medium-sized trailers. Load Range D: 8-ply rating, suitable for larger trailers or heavier loads. Load Range E: 10-ply rating, often used for heavy-duty trailers or commercial applications.
What is the difference between 75R15 and 75D15?
The D in 75D15 stands for diagonal or bias ply, indicating that the tire’s internal fabric layers are diagonally arranged, while the R in 75R15 stands for radial, meaning that the tire’s internal fabric layers are arranged radially from the center. Following the aspect ratio, you will see one of three letters — R, B or D. This letter tells you about the tire’s construction. An R designates radial tires, which have their internal cords laid at 90-degree angles to the tire’s centerline. Bias-ply tires have a D in this position to indicate their diagonal design.The D in 175/80D-13 indicates that it is a bias ply tire where as the R in 175/80r-13 indicates that it is a radial tire. The difference is how the steel belts inside are oriented. Bias ply tires are generally better in off road types of situations. Radial tires track better and run cooler.A: The D indicates that the tire is a diagonal bias ply construction and the R indicates that the tire is a radial tire construction. Because of the construction of a radial tire, the tire has more flex and will allow for more ground contact. That will improve traction and better treadwear.After the aspect ratio comes a letter to indicate the tire’s construction: P225/70R16 91S. R refers to the internal structure of your tire and gives you a general idea of its stability. There are two types of construction that you may see on the sidewall of a tire. R – Radial. D – Diagonal or Bias Ply.R” stands for the construction method of the tyre indicating the tyre is a radial tyre. The following two numbers (16) indicate the diameter of the wheel rim in inches. The next two or three numbers (94) indicate the load index of the tyre.
Which tire size is taller, 70 or 75?
Because measurement of sidewall height of the tire is a percentage of the tread section width a 75 tire would be taller than a 70 height aspect ratio tire if the section width was the same. This means that the height of the 70/80 tire is 80% of its width, or 56 millimeters if the tire width is 70 millimeters. On the other hand, the height of the 80/80 tire is equal to its width, or 80 millimeters if the tire width is also 80 millimeters. In terms of size, 70/80 and 80/80 tires have different dimensions.The 175/80-13 tires have a diameter of 24. The speed rating is based on the specific tire, not the size.How wide is a 165/80R13 tire? A 165/80R13 tire has a width of approximately 6. The width of the tire is the first number in the tire size designation, which in this case is “165”.A 205/75R15 tire has an approximate height, also known as the overall diameter, of 27. This height can vary slightly depending on the brand and model of the tire, as well as the amount of air pressure in the tire.This number represents the width of the tyre in millimeters from sidewall to sidewall. In this case, the tyre is 175 millimeters wide.
What is the difference between 75D and 75R?
The D in 75D15 stands for diagonal (or bias ply), indicating that the tire’s internal fabric layers are laid diagonally, whereas the R in 75R15 stands for radial, meaning the tire’s internal fabric layers run radially across the tire. R” stands for the construction method of the tyre indicating the tyre is a radial tyre. The following two numbers (16) indicate the diameter of the wheel rim in inches. The next two or three numbers (94) indicate the load index of the tyre.Special Trailer (ST) tires are purpose-built for trailer axle applications, catering to the specific demands of towing without consideration for passenger comfort. Unlike Light Truck (LT) tires, ST tires are engineered to endure heavy loads while being towed behind vehicles.ST on a tire size like the Loadstar ST225/75D15 Bias Trailer Tire # AM1ST96 you referenced indicates special trailer which means it was designed specifically for use in a trailer application. This type of tire can only be used on a trailer. For more info on trailer tires check out the help article I attached.LT-metric, LT-flotation and LT-numeric tires are branded with their load range (load range E or LRE) or their ply rating (10 ply rated) on their sidewalls and list their appropriate load range letter in their descriptions as LT245/75R-16 E, 7. R-15 D or 31×10. R-15 C.ST (specialty tires) will have load ranges between C (6-ply) and H (16-ply). As you would assume, the higher the letter and number of plies, the heavier loads the tires can withstand. While the tire may have a higher load range, it will not increase the capacity of the actual trailer.
