What are the tire specifications for the Ford Focus?

[StArthur]

The Ford Focus comes with three tire specifications: Focus 2021 Sedan-1.5L Manual Fengyue Model-205/60R16, Focus 2021 Sedan EcoBoost-180 Automatic ST-235/40R18, and Focus 2021 Wagon EcoBoost-180 Automatic Liechao Model-215/50R18. In 205/60R16, the first number 205 represents a tire width of 205MM, 60 indicates the aspect ratio of the tire section is 60%, meaning the section height is 60% of the width, and 16 denotes the rim diameter of 16 inches. The letter R in the middle stands for radial tire. In 235/40R18, the first number 235 represents a tire width of 235MM, 40 indicates the aspect ratio of the tire section is 40%, meaning the section height is 40% of the width, and 18 denotes the rim diameter of 18 inches. The letter R in the middle stands for radial tire. In 215/50R18, the first number 215 represents a tire width of 215MM, 50 indicates the aspect ratio of the tire section is 50%, meaning the section height is 50% of the width, and 18 denotes the rim diameter of 18 inches. The letter R in the middle stands for radial tire. Tires are one of the most critical components of a vehicle. Their main functions include: supporting the vehicle's entire weight, bearing the car's load, and transmitting forces and moments in other directions; transferring traction and braking torque to ensure good adhesion between the wheels and the road surface, thereby improving the car's power, braking, and off-road performance; working with the car's suspension to cushion impacts during driving and dampen resulting vibrations; preventing severe vibrations and premature damage to vehicle components, adapting to high-speed performance while reducing driving noise, and ensuring driving safety, handling stability, comfort, and fuel economy. Additional information on tire maintenance is as follows: Increase awareness of tire safety by regularly checking tires, especially before highway driving. Conduct thorough inspections, including tire pressure and checking the tire sidewalls for cracks and tread wear. Address any potential hazards promptly. Regularly correct wheel balance; excessive imbalance can cause high-frequency oscillations at high speeds, leading to uneven tire wear and compromising driving safety. After tire repairs, perform dynamic balance testing and adjustment; the single-side dynamic balance test value should be ≤40 grams. Rotate tires periodically to ensure even wear. Rotate tires every 5,000 km and perform a four-wheel alignment every 5,000–10,000 km to avoid abnormal excessive wear. Do not install tires of different models or with significant wear differences on the same axle. The Ford Focus tires are from the Goodyear brand, and the spare tire is non-full-size. In addition to the specifications, tires also display the following common data: Tire cord material: Indicated by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters A to Z represent certified speed ratings from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, e.g., standard rim 5.00F.

I remember when I drove a Ford Focus before, the tire model wasn't fixed—it depended on the specific year and trim. My car was a 2015 Comfort edition, equipped with 195/65 R15 tires, commonly from Goodyear. When replacing tires, you should first check the data on the door-side nameplate or the user manual to ensure you get the original specifications; wrong sizes can ruin handling and even affect fuel efficiency and safe driving. It's recommended to regularly check tire pressure and not wait until severe wear to replace them. Ideally, inspect them every two years or 50,000 kilometers—this is especially useful for long trips, as it reduces the risk of blowouts. Choosing a quiet and durable tire brand, like Michelin, can improve comfort and save money.
