Kumho Ecsta PS31 205/55 R16 91W summer Review

The Korean company Kumho has introduced another novelty Ecsta PS31, which belongs to the premium segment and is focused on use in sports cars. The tire provides improved traction, excellent handling, reduced noise effects and a long service life. The first thing to note is the maximum allowable speed for which the new model is designed - 270 km / h (according to the marking). This indicator in itself testifies to the sports orientation of the tire. As for the tread, it is distinguished by its aggressiveness combined with the direction of the design. To this should be added the use of a special rubber compound High Grip Resin (the company''s own development), which contains highly dispersed type silica and styrene rubber. These features provide the best traction that is maintained even on wet roads. And enhance the adhesion effect of the 4th longitudinal channel, which is one of the main elements of the drainage system. Moreover, 2 of them look like curved lines - it helps to increase the rate of moisture removal from the contact zone. To provide improved traction properties, the novelty tread was equipped with a continuous longitudinal rib, which is located in the central part. Such a constructive solution made it possible to improve traction and coupling performance on a dry road, providing the car with quick acceleration and equally fast braking. In addition, handling has also improved significantly, which is important for sports cars. The use of modern computer modeling technologies has made it possible to develop a tire that is characterized by optimal pressure in the contact zone, which improves handling and also minimizes the risk of damage when hitting bumps and pits. This structure made it possible to optimize wear, which is distinguished by its uniformity. The latter factor contributes to the preservation of all operational properties at a high level during the entire period of use. The longitudinal groups of blocks on the tire are equipped with special checkers with notches, as well as solid elements. This structure allows you to improve grip performance in slippery conditions. To protect against deformation effects during intensive driving and cornering, the outer blocks were made double. In addition, such elements were interconnected by jumpers, which led to a better response to the actions of the steering wheel without the risk of a violation of the tread shape. To reduce heat during high speeds, there are square recesses in the shoulder areas that act as a cooling system. They contribute to increased heat transfer, as they increase friction with air masses. Main features of Kumho Ecsta PS31 - a premium tire, which is aimed at owners of sports sedans; - has improved traction and coupling characteristics ...
