What are the effects of changing tires from 60 to 55?
2 Answers
The effects of changing tires from 60 to 55 are smoother driving, more responsive braking, and increased fuel consumption. More details are as follows: 1. The premise of changing the tire's aspect ratio is to keep the modified specification's outer diameter as close as possible to the original specification's outer diameter to reduce speedometer reading errors caused by changes in outer diameter. Changing the aspect ratio without altering the tire's outer diameter can be achieved by simultaneously adjusting the corresponding tire width and wheel size. 2. Tires are circular elastic rubber products assembled on various vehicles or machinery to roll on the ground, usually mounted on metal rims. They support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance.
I often help others change tires, and switching from 60 to 55 brings some changes. A smaller tire number means a shorter tire sidewall, which improves handling, makes the car more stable when turning, and increases braking responsiveness. However, the downside is a significant reduction in comfort, such as a noticeably stronger bump when going over speed bumps, especially when driving on rough roads where the ride becomes much more jarring. After the tire's outer diameter decreases, the speedometer may become inaccurate, showing a speed a few kilometers per hour higher than the actual speed, which can lead to misjudgment and speeding fines. Also, pay attention to tire pressure adjustments, as the new tires are more prone to bulging or bursting, especially when hitting large potholes. Additionally, the vehicle's suspension system will endure greater stress, wear out faster, and be more costly to repair. It's recommended to drive only on good road conditions and avoid bad roads.
