In recent years, the lightweight of heavy-duty trucks has been one of the research and development directions for heavy-duty truck enterprises to improve product competitiveness, and the emergence of ultra wide tires is one of the effective ways to achieve lightweight of heavy-duty trucks. It is reported that in the European and North American markets, wide section single tire (WBS) has been widely used in heavy-duty trucks. The application of wide cross-section single tires can reduce costs, reduce mass, reduce wear and fuel consumption.
It is understood that in the past 10 years in China, fuel prices have skyrocketed, and there is a trend towards increasing the use of WBS tires. However, in some regions of China, due to the limitation of maximum allowable axle load, wide section single tires cannot be widely used. However, with the lightweight design and application of heavy trucks and trailers, the development of single tires has become an irreversible trend.
Advantages of single tire compared to traditional twin tires
So what are the advantages of single tires compared to traditional twin tires It is understood that there are the following advantages
1. Lighter self weight
The weight of 12R22.5 (including wheels) is 224Kgtwin tire; 42565R22.5 (including wheels) with a weight of 153Kgsingle tire; If the main trailer is equipped with ultra wide tires, the entire vehicle can reduce weight (224-153) × 10=710Kg; Replacing the drum brake with a disc brake allows the main vehicle to lower its self weight by 135Kg; The overall weight reduction of the traction train is 710+135=845Kg, with an annual driving distance of 150000 to 250000 kilometers, which can bring in a profit of 35000 to 60000 yuan.
From an appearance perspective, the most direct is that large single tires are wider than regular tires, replacing traditional twin tires with single tires. Compared to the dual tire combination, the large single tire has a lighter weight, reduced friction, and lower manufacturing and usage costs.
2. Lower fuel consumption
Ultra wide tires have a 23% contact area with the ground, a 6-8% reduction in fuel consumption, and a fuel saving of over 2L per 100 kilometers compared to twin tires; Due to fuel saving, it can bring a value of 21000 to 35000 yuan to customers.
The results of road testing in the United States indicate that the improvement in fuel economy ranges from 3% to 18%. More importantly, with the reduction of fuel consumption, the nitrogen oxide emissions from vehicles are reduced by 9% -45%, promoting environmental protection in the logistics industry. Moreover, ultra wide single tires can effectively reduce the weight of the vehicle body and have a significant lightweight effect.
3. Lower tire consumption
Ultra wide tires reduce costs by 20% compared to twin tires, at approximately 744 yuan per set, and tires are replaced at least once a year; Due to the reduction in tire consumption costs, it brings a value of approximately 7500 yuanyear to customers. The maintenance cost of tires has been reduced, which is equivalent to reducing operating costs. Why not The comprehensive value brought by super single tires to customers can reach 63000 to 100000 yuan per year, with a three-year service life of 200000 to 300000 yuan, which is a considerable amount of economic benefits.
