Tyres Constancy

The Constancy trademark belongs to the Chinese company Yuelong. It was founded in 1986 and is engaged in the development and manufacture of a full range of automotive tires. The suppliers of raw materials, technologies, and equipment are leading companies in their fields. Currently, Yuelong's enterprises produce around 5.6 million tires per year. Among the six trademarks owned by this Chinese company, Constancy "specializes" in tires for trucks and buses, special equipment used in construction and mining.

A significant part of the tire products of this brand are represented by tires for trucks. They are distributed across the following categories:

- for long-haul transportation;
- for regional transportation;
- for mixed operating conditions.

Long-haul tires differ depending on the installation location and road conditions. The differences in tire design are significant enough to provide them with maximum efficiency. Additionally, it is worth noting the use of special compounds that are resistant to wear, punctures, and tears, as well as the ability to intensely dissipate heat from the carcass, reducing rolling resistance. Another important feature is the presence in the lineup of tires designed for use in complex winter conditions. Such models are distinguished by "block" tread patterns and a tread depth of around 20 mm, compared to 12 mm for standard "long-haul" tires.

Regional tires of the brand are universal models that can be used even on unpaved roads. They are characterized by a greater tread depth. For most models, this indicator fluctuates around 15 mm. Additionally, rubber compounds with increased mechanical strength are used. In combination, these factors significantly reduce the risk of tire damage during operation in complex conditions. It is also worth noting the use of tread patterns of several types with different degrees of adaptation to asphalt roads and unpaved surfaces. As a result, some of them can be used, including in dump trucks, concrete mixers, and garbage trucks.

"Mixed" truck tires are distinguished by their greatest strength and reliability. They use carcasses with an increased number of layers of steel cord. Another difference is the greater thickness of both the sidewalls and the tread of the tire. Additionally, the most durable compounds are used, which are resistant to tears, cuts, and abrasive wear.

A significant part of the tire range is represented by industrial tires. The scope of their application is trucks and wheeled special equipment used in the mining industry. Externally, such models are distinguished by their unique tread patterns, which are most effective on rocky surfaces. The tire tread is made of a particularly durable rubber compound that is not prone to heating under high loads, with a very high resistance to chips, cuts, and abrasive wear. At the same time, the tread depth of the tread pattern fluctuates around 23-24 mm.
