GRENLANDER is a tire brand under Milestar. Here are the specific details about the Milestar brand tires: 1. Utilizing Goodyear technology from the U.S., the tires are made from imported natural rubber from Indonesia and Malaysia, undergoing over 500 processes to produce high-performance semi-steel radial tires with more than 1,000 varieties. 2. Shandong Longyue Rubber Co., Ltd. has three series of tires under its brand: Connies, Yilian, and Milestar. 3. In terms of rotation speed: When ECO mode is activated, the vehicle automatically matches the optimal rotation speed to reduce unnecessary fuel consumption. The CVT sets a special shifting speed and ratio for ECO mode, making the engine rotation speed change more smoothly compared to normal mode, thus making ECO mode more energy-efficient and environmentally friendly than normal mode.

I'm the kind of person who loves to delve into various car components. I know Goodyear tires have been around since 1898—over a century of heritage speaks volumes about their solid reputation. Their standout features are wear resistance and grip, especially their excellent wet-weather drainage, making high-speed driving feel firmly planted. I’m particularly fond of their run-flat technology, which lets you drive another 50–80 miles even after a puncture—perfect for someone like me who frequently takes long trips. However, after prolonged use, I’ve noticed that Goodyear’s premium series leans toward stiffness, with road noise noticeably louder than Michelin’s, though the durability is indeed superior. Their recently introduced silent foam technology is addressing this, and I think it’s becoming increasingly practical for family cars.

Our auto repair shop handles hundreds of tires daily, and Goodyear's models are exceptionally comprehensive. The economical Assurance series focuses on wear resistance, with treads still deep after 70,000-80,000 kilometers on sedans. The EfficientGrip Performance II adds a noise-reducing layer, making highway driving much quieter. For those who enjoy handling, the Eagle F1 is the choice, offering exceptional stability during cornering. For SUVs, there's the Wrangler off-road tire with reinforced sidewalls, perfect for rough terrain without fear of scratches. Currently, Goodyear supplies original equipment tires for luxury cars like and Mercedes-Benz, even Tesla Model Ys come with their tires from the factory. When changing tires, remember to check the production date—the last four digits of the DOT code on the sidewall indicate the year and month.

Three years ago, I replaced the tires on my Lavida with a set of Goodyear DuraPlus, and they've been quite durable after running over 50,000 kilometers. What surprised me the most was their performance in rainy conditions. Once, during a heavy rainstorm, I drove through standing water at high speed, and the steering wheel barely shook. The tire noise is acceptable at low speeds, but once you hit 80 km/h, the wind noise overtakes the tire noise. During a check this year, the mechanic said the tread depth was still at 4 millimeters, good for another 20,000 kilometers. However, the braking distance is slightly longer on icy roads in winter, so I later spent extra to switch to a set of winter tires. If you're after absolute comfort, Michelin might be a better choice, but in terms of cost-effectiveness, Goodyear is truly hassle-free. The four tires cost me over 600 yuan less than what my friend spent on another brand.

For those who are into car modifications, you know Goodyear's performance on the track is truly top-notch. Semi-slick tires like the Eagle F1 SuperSport allow us to take mountain corners by stepping on the gas and cutting straight to the apex—the sidewall support is much stronger than Bridgestone. Last year, using Goodyear tires on Tianma Circuit shaved 1.2 seconds off my lap time compared to Michelin PS4, though the trade-off is a bit more tire noise. Regular car owners should choose tires based on their usage scenarios: For frequent highway driving, the EfficientGrip series is recommended for its fuel-saving silica tread compound; off-road enthusiasts should try the Wrangler All-Terrain AT tires; for daily commuting, the Assurance Comfort is more than enough. Remember not to mix tires from different brands, as it can affect handling.

Recently spent a lot of time helping my cousin choose tires, and Goodyear's cost-performance ratio is truly impressive. For regular family sedans, the Assurance series is a great choice at around 400 yuan per tire with a 5-year lifespan, 30% cheaper than Michelin. For high-end cars, consider the Excellence series, which offers top-level quietness and wet braking performance. The best deals are during major e-commerce – last year's Double 11 sale offered four tires with installation for just 1,600 yuan. Be careful not to buy old stock tires as rubber hardens after three years. For rear-wheel drive vehicles, I recommend prioritizing rear tire replacement, while front-wheel drive vehicles should replace front tires first. If you frequently drive on snow/ice surfaces, it's best to have dedicated winter tires as all-season tires start slipping at -10°C.
