Cooper unveils new Mastercraft and Starfire off-road tires


Cooper Tire Asia introduced two new tires of its brands for SUVs, developed by specialists of the company's technology center in Chinese Kunshan specifically for sales in the Chinese market.

The new Starfire 710 all-terrain tires are designed to equip all-wheel drive SUVs and are highly durable and safe. The unique tread pattern of the Starfire 710 provides excellent traction in mud, sand and soft ground. Traction characteristics of the tire are enhanced by the special 3D design of the shoulder blocks of the tread, and a multilayer carcass increases the resistance of the tire to mechanical damage. In addition, the Starfire 710 provides a soft ride with low noise, both on smooth asphalt and when driving on broken roads.

Starfire 710 tires are available in 10 sizes for wheels with a bore diameter of 16 to 18 inches. Two more sizes will be added to the size range of the model in the second half of this year.

The second novelty for the Chinese market is the Mastercraft Courser Sport 100 Ultra High Performance tire for crossovers. The tread of this new tire has an asymmetric design that provides precision control at high speed. Wide longitudinal grooves and a new rubber compound with silica incorporate exceptional grip on wet surfaces. The novelty provides a comfortable and quiet ride, and also has an attractive appearance.

What is tire pressure and how is it measured?

At the initial stage, the tire acquires the necessary rigidity due to the correct proportions of the components in the rubber. But you can start using it only by pumping the necessary amount of air inside, creating internal resistance. The force with which it acts on the tire is the pressure in it.

The most common units are bar (Russia) and PSI (Europe and the USA). In the first case, pressure is measured in atmospheres or kilograms per cm². And the second uses the ratio of pounds to square inches. Converting PSI to bars is easy: just divide the value by 14.5 (or do the opposite if you need to convert the bars to PSI).

What does tire pressure affect?

A number of important characteristics depend on whether the wheels are properly inflated.

Manageability. The easiest way to understand that the tire pressure is incorrect is to monitor the behavior of the car. A stiffer compared to the usual move, when every bump and pit is felt, and the low sensitivity of the brake indicate that the wheels are pumped. A decrease in reaction to gas and steering turns signal a lack of air in the cylinders.

Tire wear . Incorrectly set pressure leaves a mark on the tread. The pumped wheel touches the road with only the central part instead of the entire tire area, so over time it is erased in the middle. And the flat, on the contrary, rests on the canvas with the edges, which are first surrendered. In both cases, the rubber will have to be changed ahead of schedule.
