What are load range D tires?

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 does load range D mean on trailer tires?

The load range is the load capacity of the trailer tire. A tire's load range is located on the sidewall of the tire. The load range is rated with a single letter, such as B, C, D, etc. If you have two tires of the same size but one with a load range of B and D, the D range tire will have a higher weight capacity.

How much weight can a load range D trailer tire carry?

The D load range is rated for 2,540 pounds at 65 psi. And the E load range is rated for 2,830 pounds at 80 psi. If you had a single axle trailer with a gross weight rating of 5,000 pounds, you would use the D or E tires in this size since the C tires would be under rated for the weight.

What's better load range D or 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.

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.

What does the D mean on a trailer?

D-Value (Articulated Truck/Towed Trailer Coupling)

The D-value is stamped into the type plate on a trailer coupling. Its unit is kN. The D-value can be calculated from the permissible total mass of the towing vehicle and trailer. The higher the D‑value, the greater the mass that can be attached to a coupling.

Do I need 10 ply tires?

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.

What load range is a 14 ply tire?

Load Range Capacity and Ply Ratings

This article focuses on 14 ply trailer tires (load range G), which is the highest capacity you can get. 14-ply rated trailer tires can sustain pressures of up to 110 psi (760 kPa), and weight of over 4,000 lbs per tire.

Are 6 ply tires good for off-road?

6 ply is not the requirement for a rugged off-road tire. The most common off-road tire failure in is the sidewall - cuts and punctures by rocks, trees and brush, etc. In fact a 6 ply truck tire will typically provide an unduly stiff ride on a [light-weight] Jeep.

Should I put 80 PSI in my tires?

The 80 psi is required if the tire is operating at rated load. You most likely have a load range E tire.

Do 10 ply tires ride rougher?

Yes, it will. The other downside is 10-plies are substantially heavier, which will drop your fuel mileage (you're going from low 40s lbs/tire to mid 50s). There are a fair number of P-metric 275/60R20s out there (with the Defender LTX M/S being one of the best options).

Should I run my truck tires at max PSI?

In most of these cases, 40 psi should be more than enough, and since most modern tire designs will allow up to 44 psi (in some cases more) this is not a problem. If you have a heavily loaded vehicle, up to 44 or even higher is ok if the tire allows it, but this is a little high for most vehicles.

Which is better D or R tires?

A radial tire flexes more than a bias tire, giving it better ground contact, traction, stability, and tread wear. A radial tire will normally run cooler than a bias ply tire, especially when the tire is under a load. A tire that runs cooler will last longer. For those reasons I would recommend an R tire over a D tire.

What does the D mean on a wide load?

You may be wondering what the "D" stands for. This is an abbreviation for over dimensional. Reversible lettering with 6 grommets and reinforced edges.

What is the difference between R and D trailer tires?

The difference between the two trailer tire sizes is that the letter D in the first size you listed ST205/75D15 stands for bias ply and the letter R in the tire size that they put on your vehicle stands for radial.

What type of trailer tires are best?

Goodyear's Endurance line is one of the best rated trailer tires out there. It features Durawall technology that keeps the sidewalls highly resistant to wear and tear. These trailer tires are also designed to stay cooler during long drives, which prolongs the tread life.

What load range tire do I need for my truck?

How to Determine Tire Load Capacity. 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.

Do trailer tires need to be balanced?

The answer is yes, you should. Although you may meet RVers and travel trailer owners who disagree, balancing your travel trailer tires is actually necessary for improved performance, tire longevity, and safety factors. Passenger vehicle tires need to be balanced for ride stability and comfort, as well as for function.

Do load range F tires ride rough?

Typically, an F rated tire will ride a bit worse than an E rated tire, but there are some exceptions. Load range refers generally to a side ply rating, while load index refers to a tire's weight rating.

Is a higher load rating better?

The load rating can be located on the sidewall of all tyres and is represented by a numerical value. The higher the load rating number, the stronger the tyre. Tyres with a higher load rating can take a greater amount of air pressure, which means they can also carry heavier loads.
