Which manufacturer produces Diamond tires?

Products of Guangzhou Fengli Rubber Tire Co., Ltd. Composition of tires: Tires are usually composed of three parts: the outer tire, the inner tube, and the bead filler. The inner layer of the tire body has a rubber layer with excellent air tightness and requires special rims. The structure of tires worldwide is developing towards tubeless, radial, flat (small ratio of tire section height to width), and lightweight designs. Outer tire: The outer tire consists of the carcass, the breaker (or belt layer), the tread, the sidewall, and the bead. The cross-section of the outer tire can be divided into several separate areas: the crown area, the shoulder area (tread slope), the flex area (sidewall area), the reinforcement area, and the bead area.

Diamond Tire is a product of Shandong Changfeng Tire Co., Ltd. The factory is located in Dongying, Shandong, mainly targeting the mid-to-low-end market, specializing in producing tires for passenger cars and light trucks. When I was researching tire replacements before, I looked into their products and found they focus on wear-resistant and economical tires, which are particularly suitable for regular family cars or ride-hailing drivers. The price is about one-third cheaper than international big brands, but the treadwear index can exceed 500, capable of lasting 50,000 to 60,000 kilometers without issues. However, the noise reduction performance is average, with noticeable tire noise at high speeds. If you primarily drive in urban areas for commuting and have a limited budget, you might consider trying this brand.

In our car owners' group, people often ask about Diamond tires. They are indeed produced by Shandong Changfeng Tire Factory. There's a cluster of tire manufacturers in Dongying, and Changfeng is quite large-scale, operating since 2004. Last year, I replaced four tires with Diamond's silent series and found their wet grip performance quite good, with minimal hydroplaning through waterlogged areas. The price is genuinely cheap, just over 200 yuan per tire. However, the sidewall support is somewhat soft, with noticeable body roll during sharp turns on mountain roads. This manufacturer also does OEM exports, with many low-cost cars in Southeast Asia using their rebranded tires as original equipment.

The manufacturer of Diamond tires is Shandong Changfeng, specializing in economical car tires. Last week, I just helped my neighbor replace a set of Diamond HT series tires for SUVs. The tire tread design is quite deep with wide drainage grooves, making them particularly suitable for rainy areas like ours in the south. The manufacturer conducts high-speed tests up to 210km/h before leaving the factory, so they are more than adequate for daily driving at 120km/h. Their biggest advantage is the affordable price, being half the cost of Michelin for the same specifications. However, the rubber compound is on the harder side, resulting in a bumpier ride over speed bumps. If you're on a tight budget but want durability, Diamond tires are a solid choice.

Shandong Changfeng Tire's Diamond brand is considered an old-timer among domestic tires. I've visited their workshop, which features fully automated production lines capable of outputting 20,000 tires daily. They use imported rubber from Thailand and reinforce the carcass with two layers of polyester cord, making them more puncture-resistant than regular tires. I particularly recommend their winter tires - the ice groove design is quite scientific. Last winter, I drove through Heilongjiang without any skidding. The only downside is the new tire smell when they come out of the factory, which takes a few hundred kilometers to dissipate. The manufacturer mainly supplies to platforms like JD Auto Service now, making installation convenient.

Having worked in car repairs for over a decade, Diamond tires are what I've seen the most. Produced by Shandong Changfeng, the factory is located in Guangrao County, known as the 'Tire Capital.' The most notable feature of these tires is their thick sidewalls, making them less prone to bulging when scraping against curbs. I've tested the bolt hole positions with a torque wrench, and their tolerance control is better than some off-brand tires. The economy series has a high silica content, with treads still one-third remaining after 70,000 to 80,000 kilometers. However, pay attention to the production date; tires stored for over two years may experience rubber aging. The manufacturer has now introduced a new series specifically for new energy vehicles, which don't deform even at a tire pressure of 3.0.
