The Fit uses Michelin tires. The functions of tires are: 1. To support the entire weight of the vehicle and bear the load of the car; 2. To transmit traction and braking torque, ensuring the adhesion between the wheels and the road surface; 3. To reduce and absorb the vibration and impact force during driving, preventing severe vibration and early damage to car components; 4. To adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency. Taking the 2021 Fit as an example, it is a compact car equipped with a 1.5L naturally aspirated engine, with a maximum horsepower of 131 PS, a maximum torque of 155 Nm, and a maximum power of 96 kW.

I've been driving a Fit for almost four years, and the original tires are Bridgestone Ecopia series in 185/60R15 size, which are quite quiet and fuel-efficient for daily city driving. If you frequently drive on highways, I recommend switching to Michelin or Dunlop summer tires for better grip. Tire size directly affects handling stability and fuel consumption; larger tires make steering heavier but improve cornering stability. Related topics include seasonal adjustments: choose tread patterns with good drainage for rainy summers, and switch to winter tires to avoid slipping on snowy roads. I usually check tire pressure once a month, maintaining it around 230kPa, which can extend tire life by one to two years and save some fuel costs. Consider replacing all tires every three to five years or after driving 40,000 to 50,000 kilometers. Check the wear depth in the central area; replace them promptly when they become shallow, don't wait until braking distance increases.

When I bought my Fit two years ago, it came with Yokohama 175/65R15 tires, which were sufficient for daily family driving, providing a smooth and comfortable ride. After using them for over a year, I noticed slight cracks on the sidewalls, likely from curbing, so I decided to switch to Goodyear fuel-efficient tires, saving a few dozen yuan per tire. For the replacement, I went to a professional shop to avoid installation issues and compared online prices to save costs. A related topic is fuel efficiency impact: maintaining correct tire pressure can reduce fuel consumption by 3-5%, so I always keep a portable air pump for emergencies. Tire lifespan depends on driving habits—frequent hard braking accelerates wear, typically requiring replacement every three to four years. Money-saving tips include rotating front and rear tires; proper maintenance can extend their life by about half a year. Overall, the original tires cost just over 300 yuan each, offering decent value for budget-conscious drivers like me.

The standard tire size for the Fit commonly includes 185/60R15 or 175/65R15, featuring a 185mm width, 60 aspect ratio, and 15-inch wheel diameter combination, suitable for compact car design. Correct tire selection optimizes vehicle performance, such as matching the load index and speed rating to the factory specifications. A related topic is tire pressure maintenance, recommended within the range of 220-250kPa, as high or low values directly affect driving stability. When replacing tires, consider the road conditions, as grip varies significantly between dry and wet surfaces. Regularly check the tread depth and replace immediately if it falls below 1.6mm to ensure safety.
