What is the tire model specification of the Changan CS55?
3 Answers
The tire models for the Changan CS55 are 225/60R17 and 225/55R18. It is a model under Changan Automobile, with exterior dimensions of 4500mm in length, 1855mm in width, and 1690mm in height, a wheelbase of 2650mm, and a body structure of a 5-door, 5-seat SUV. The Changan CS55 is equipped with a 1.5T turbocharged engine, paired with a 6-speed manual transmission and a 6-speed automatic transmission, delivering a maximum horsepower of 156, a maximum power of 115 kW, a maximum power speed of 5500 rpm, and a maximum torque of 225 Nm.
I've been driving the Changan CS55 as my daily commuter, which comes with factory-fitted 225/55 R18 tires. The 225 represents a tread width of 225 millimeters, 55 is the aspect ratio, R indicates a radial structure, and 18 is the wheel diameter in inches. This specification is well-balanced, with moderate tread width providing agile handling in urban areas while still coping well with uneven roads in the suburbs. The 55 aspect ratio makes the suspension softer, ensuring comfort on long drives without back strain. When changing tires, I also noticed this size helps maintain fuel efficiency, saving about 1-2 liters per 100 kilometers on average. However, it's important to regularly check tire pressure, ideally maintaining 2.4-2.5 bar to extend tire life. For highway driving, I find the grip stable, especially in rainy conditions without slipping, enhancing safety. Note that there might be slight variations across different model years, so it's best to consult the manual for confirmation.
As a tech enthusiast who has been paying close attention to automotive details, I've studied the Changan CS55's standard tire specification of 225/55 R18 extensively. The 225mm width provides ample contact patch for superior handling response. The 55 aspect ratio means the sidewall height is 55% of the width, offering excellent cushioning effect that's particularly suitable for SUV chassis, ensuring comfort over rough roads. The R18 wheel size strikes a perfect balance between visual appeal and practicality. Key considerations for this specification include optimized vehicle weight distribution (improving fuel efficiency by approximately 10%) while maintaining good durability, with mainstream brands like Goodyear or Michelin offering compatible options. For performance upgrades, I'd prioritize high-performance tires in the same size to enhance grip, but would avoid arbitrarily increasing wheel size to prevent interference with the suspension system.
