The appropriate tire pressure for a scooter motorcycle is: 1. Front tire: 170 to 180 kPa; 2. Rear tire: 200 to 220 kPa. Hazards of abnormal tire pressure: 1. Reduced friction and adhesion of the tire, affecting braking performance; 2. Causes steering wheel vibration and deviation, reducing driving comfort; 3. Accelerates localized wear of the tread pattern in the center of the tire, shortening tire lifespan. 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 mitigate and absorb vibrations and impact forces during driving, preventing excessive vibration and premature damage to automotive components.
