The original tire specification for the classic Ford Focus is 195/65R15. Below is a related introduction to tires: 1. Functions of tires: Mainly include dry grip, hydroplaning resistance, providing comfort, reducing driving noise, impact resistance, wet grip, load-bearing capacity, handling performance, average wear, and mileage. 2. Cross-sectional structure of tires: Generally, it can be divided into four parts: tread, shoulder, sidewall, and bead. Each part has its own function. The tread mainly contacts the ground, the shoulder and sidewall provide support, and the bead contacts the wheel rim to provide sealing. 3. Internal composition of tires: The internal structure of a tire consists of multiple layers of different materials: tread pattern, overlay, steel belt layer, stress-absorbing rubber strip, carcass ply layer, and inner liner.

Last time I helped a friend check out a 2018 Focus hatchback, the factory-fitted tires were 205/60 R16. But it really depends on the specific year - the older 1.6L automatic Trend model used 215/50 R17, and the Sport version even came with 235/40 R18 big wheels. Just a reminder that the tire size numbers are embossed on the sidewall, you can see the steel imprint by squatting down. When changing tires, don't just focus on the brand - remember the number after 'R' indicates the rim size, getting it wrong may cause interference with brake calipers. By the way, my neighbor tried to save money by installing wrong-sized tires, and ended up with skyrocketing fuel consumption - definitely not worth it.

My 2015 Focus hatchback is equipped with Goodyear 205/55 R16 tires, which are a bit noisy but quite wear-resistant. Later, I saw the new owner's manual at the dealership and noticed that Michelin tires are now standard. Actually, tire width and aspect ratio have a noticeable impact on driving. Wider 215 tires provide better cornering stability but consume more fuel, while low-profile tires are more prone to bulging. When changing to winter tires, it's best to refer directly to the owner's manual for the most accurate information. Last time, my cousin was tricked into installing 225 tires, and they kept rubbing against the wheel arches when turning.

After checking the database, it was found that the classic Focus mostly uses 195/65 R15 tires, while the 12th-generation facelift model is equipped with 205/60 R16 tires. The ST-Line version directly comes with 235/40 R18 performance tires. A reminder for car enthusiasts planning to change tires: the third number represents the rim size, so don't confuse 16-inch and 18-inch when buying wheels. Aligning the yellow dot on the tire sidewall with the valve stem during installation can reduce vibration—this trick from an experienced mechanic isn't something I'd share with just anyone.
