What is the advantage of a large single tire over a regular tire?

The scientific name of a large single tire is "wide cross-section tire", the international general cross-section of more than 385mm tire is called a large single tire, and the domestic refers to the large single tire its cross-section width can generally reach 425mm or 445mm.

The biggest feature of large single tire is wide, the original side of the need to install two tires side by side of the vehicle, the use of large single tire only need to install one tire, so the use of large single tire vehicles than the use of ordinary tires of the total number of vehicles.

This directly relates to a very obvious advantage of large singlets: low self weight. According to relevant estimates, a 425/65R22.5 large single compared to two 285/80R22.5 twin, the weight can be 70kg-80kg lighter, if the three axes can be used to large single, it can reduce the weight of 420kg-480kg or so. In the increasingly strict environment of overpower, the reduction of vehicle weight often means that more goods can be loaded, and the operating income of the vehicle can be improved to a certain extent.

In addition, a large single tire compared with two ordinary tires, the contact area with the road has been reduced to a certain extent, rolling resistance and friction are relatively small, coupled with light weight, can make the vehicle run more fuel-efficient. Relevant experimental data show that if the three-axle semi-trailer and tractor are installed at the same time, the fuel consumption of 100 kilometers can be reduced by about 6%, which can effectively reduce the cost of comprehensive vehicles for owners who often run long distances.

Some car owners wonder: If the benefits of a large single tire are so obvious, why do most cargo vehicles still use regular tires? Speaking of this, the trailer axle has to mention its disadvantages, after all, everything has cracks, and the advantages will turn into disadvantages under certain conditions.

For example, the contact area with the road is small, although it can save fuel, in the case of reduced friction, the driving force of the wheel will also decrease at the same time, in addition, if it encounters rain and snow weather, it is more likely to lock the wheel, slip, idling, affecting driving safety;

The load-bearing resistance is relatively poor, and the load-bearing capacity of an independently installed large single tire is less than two side-by-side tires, and the practicality of a large single tire is another matter in some heavy loads or complex working conditions. In some extreme cases, such as a flat tire, if it is two tires side by side, one of them can rely on the other to barely drive to the maintenance station, but the large single tire once the flat tire vehicle will immediately lie down;

At the same time, the price of large single tires is also higher than ordinary tires, the maintenance difficulty is relatively greater, and the more critical is that the matching requirements of the axle are also high.

Usually the owner of the two-tire trailer axle if directly replaced into a large single tire, easy to lead to a large deviation of the wheel base, easy to affect the stability of the vehicle, if the vehicle is fully loaded, or when the center of gravity of the loaded goods is high, driving to the complex mountain section or sharp turns, pothole road surface, will seriously affect driving safety. Therefore, if you want to modify a large single tire, you must choose a trailer axle with fully matched parameters. It is recommended that you choose the trailer axle products of Darong Group, drum type, disk type, low plate, external type, model specifications are complete, can be customized according to the actual needs of customers.

Overall, it is true that the large single tire has light weight and fuel saving efficiency, but it is only for long-distance standard load or other similar operating conditions, if it is often run heavy load, driving road conditions are complex, it is necessary to carefully consider changing the tire, do not blindly follow the trend, which is the best for their own use.
