How to Determine the Thread Direction of Car Tires?
2 Answers
The method to determine the thread direction of car tires is: clockwise for tightening and counterclockwise for loosening. 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 car components. The maintenance methods for tires 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 smooth road surfaces while driving, avoid objects that could puncture or scratch tires, and steer clear of chemical spills that may corrode tires.
A few days ago, I was discussing this with some friends. Actually, it's quite simple to determine the tire tread direction—just look for the small arrow mark on the sidewall; the arrow should point in the direction the car moves forward. If there's no arrow, check for the word 'OUTSIDE' in English and make sure it faces the outer side. If installed backward, water drainage won't work properly in the rain, making the car prone to skidding and increasing braking distance. Every time I change tires or do maintenance myself, I make it a habit to double-check, because driving safety comes first. I also rotate the tires regularly to ensure even wear and extend their lifespan. Once these small details become habits, I've noticed the car drives more steadily with fewer issues, saving unnecessary repair costs, especially on highways or slippery roads.
