SP-SPORT-MAXX is a run-flat tire launched by Dunlop, a Japanese tire brand under the Sumitomo Group. Originally founded in Japan by the British Dunlop Company, it was later taken over by the staunchly right-wing Sumitomo Group during World War II when Japan declared war on Britain. The predecessor, the British Dunlop Company (DUNLOP), was a renowned British brand known for applying high-tech achievements to sports equipment design, helping athletes reach their personal limits. It represents modernity, trendiness, and avant-garde style, and has long been a brand favored and endorsed by world-class athletes. Dunlop Tires has launched a new tire model, the SP-SPORT-MAXX 050+, specifically designed for luxury sedans. It is a comprehensive tire product focusing on wet grip and comfort. The average tread hardness of the Dunlop SP-SPORT-MAXX 050+ is 58HA, the groove hardness is 58HA, and the sidewall hardness is 42HA. It features a carcass reinforcement structure with more than two layers of high-strength nylon, effectively reducing energy loss during driving and distributing ground pressure evenly to the tire shoulders, optimizing the contact shape and enhancing high-speed handling performance. Dunlop tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes during driving. Therefore, they must have high load-bearing capacity, traction, and cushioning performance, as well as high wear resistance and flex resistance, along with low rolling resistance and heat generation. They directly contact the road surface and work with the vehicle's suspension to absorb shocks during driving, ensuring good ride comfort and smoothness. They also ensure excellent adhesion between the wheels and the road, improving traction, braking, and off-road capability while bearing the vehicle's weight. Dunlop tire maintenance methods: Increase awareness of tire safety and inspect tires regularly. Regularly correct wheel balance; unbalanced wheels can cause high-frequency oscillations at high speeds, leading to uneven tire wear. Perform tire rotation periodically. To ensure even wear on all tires of the same vehicle, rotate the tires every 5,000 kilometers. In daily use of Dunlop tires, pay attention to the following: Regularly check the tire surface for cracks, deformations, or other defects. As tires wear, the tread grooves gradually become shallower. If the tread is worn flat, it loses its drainage and anti-slip functions, significantly reducing the vehicle's performance. Small cracks can also pose a risk of blowouts at high speeds. Additionally, promptly remove pebbles from the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that may degrade rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water to cool tires. In hot weather or after high-speed driving, tires can overheat, and tire pressure may increase. In such cases, park to allow the tires to cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Minimize frequent or hard braking to prevent accelerated tread wear due to dragging between the tires and the road.
