zmax is a sub-brand of Zhengdao Tires. Zhengdao Tire Co., Ltd. (abbreviated as Zhengdao Tires) was established in 2011 and is located in Heze City (Caoxian County), Shandong Province, renowned as the "Hometown of Peonies". It is adjacent to four provinces: Hebei, Henan, Anhui, and Jiangsu, boasting a superior geographical location. It is a high-tech tire enterprise integrating product research and development, production, and . When using Zhengdao Tires in daily life, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves of the tires gradually become shallow. If the tread is worn flat, it will lose its drainage and anti-skid functions, significantly reducing the vehicle's performance. Seemingly minor cracks can be potential hazards for tire blowouts during high-speed driving. Additionally, promptly remove pebbles from the grooves; try to park on flat ground. Avoid parking on roads with thick, sharp, or pointed stones. Do not park the vehicle near or in contact with petroleum products, acids, or other materials that may deteriorate rubber. After parking, the driver should not turn the steering wheel, as this operation accelerates tire wear; do not splash water for cooling. In hot weather or during high-speed driving, tires are prone to overheating, and the air pressure increases. In such cases, park to dissipate heat, but never release air to reduce pressure or splash water to cool down, as this may cause abnormal aging of the tread rubber; avoid sudden braking. Try to minimize frequent use of brakes and emergency braking to prevent accelerated tread wear due to dragging between the tires and the ground.

Actually, ZMAX is a tire brand I frequently encounter at tuning shops. It focuses on cost-performance ratio and sporty performance, making it especially popular among young car enthusiasts like us. This series features an asymmetric tread pattern design, providing noticeably better wet grip than regular tires, along with solid lateral support during high-speed cornering. However, road noise becomes quite noticeable above 80 km/h, making it a performance-oriented yet affordable choice suitable for budget-conscious owners who don't want to compromise handling. Remember to check the speed rating when selecting – the ZR rating supports top speeds over 240 km/h.

Last week, I just helped a friend replace four ZMAX tires, which belong to the wear-resistant sports tire series. The four wide drainage grooves on the tread are very practical, especially when driving through waterlogged roads during the rainy season in the south, as they prevent slipping. The rubber compound is mixed with silica, reducing rolling resistance by about 8%, which is quite fuel-efficient. However, what impressed me the most was the price. The 225/45R17 specification is nearly 400 yuan cheaper per tire compared to Michelin, offering great value for money. The downside is slightly reduced comfort, as the ride over speed bumps feels more direct and bumpy.

ZMAX tires are mid-range performance tires, focusing on dry and wet handling. Their unique feature is the reinforced shoulder design, which noticeably improves responsiveness during cornering. In summer tests under 35-degree high temperatures for two continuous hours, the rubber softening was better controlled than some major brands. Recently, it's been observed that many ride-hailing drivers use this series, as the treadwear rating reaches 420, making it common to replace tires after 80,000 kilometers.

The reason for paying attention to ZMAX tires is mainly due to their track DNA, as many amateur touring car racing teams use them as training tires. The three-layer polyester cord in the tire sidewall is hardcore enough, and the 40 aspect ratio makes it less prone to bulging when going over curbs. Last week, using a professional tire pressure gauge, the cold tire pressure of 2.5bar stabilized at around 65 degrees after half an hour of driving, with heat dissipation performance exceeding expectations. Performance car enthusiasts are recommended to choose high-viscosity models for better low-temperature grip.

Veteran mechanics often praise ZMAX as the people's champion tire, with a focus on durability and safety. The tire sidewalls feature two layers of high-density nylon reinforcement, making them highly resistant to damage from curb scrapes. Its winter performance is particularly noteworthy—the tread rubber remains flexible even at -5°C, delivering about 1.5 meters shorter braking distance on ice compared to some all-season tires. However, pay attention to the manufacturing date: if the tire has been in storage for over two years, the rubber compound tends to harden. A stronger rubber smell indicates a fresher tire.
