What is the aspect ratio?

[DeCali]

Aspect ratio refers to the ratio of the height from the rim to the tread surface to the measured width of the tire's cross-section, expressed as a percentage, meaning the height as a percentage of the width. The functions of tires are: 1. Transmit driving force, braking force, and steering force to achieve vehicle operation; 2. Support vehicle load; 3. Reduce and absorb vibrations and impacts during driving, avoiding severe vibrations that could damage vehicle components. Tire maintenance methods include: 1. Regularly clean stones stuck in tire treads; 2. Minimize exposure to direct sunlight; 3. Promptly check tire pressure; 4. Pay attention to suspension maintenance; 5. Periodically inspect front wheel alignment; 6. Adopt careful driving habits, choose road surfaces wisely, avoid objects that could puncture or scratch tires, and steer clear of chemical spills that may corrode tires.
