Differences Between Full-Size and Non-Full-Size Tires
1 Answers
The differences between full-size and non-full-size tires are as follows: Size difference: A full-size spare tire refers to a spare tire with the same specifications as the four original tires on the car, usually equipped with the same rim as the original wheel; a non-full-size spare tire is narrower in tread width or has a smaller rim size, typically using a steel rim. Speed difference: Non-full-size spare tires have speed restrictions (maximum speed not exceeding 80 km/h) and can only temporarily replace the original tire. Full-size spare tires have no such restrictions. Weight difference: Full-size spare tires, being identical in specifications to the original tires, are much heavier than non-full-size spare tires. In daily use, the following points should be noted for tires: Regularly check the tire surface for cracks, deformations, or other defects. Due to wear from driving, the tread grooves gradually become shallower. If the tread is worn flat, it loses its drainage and anti-slip functions, significantly reducing the car's performance. Small cracks can be potential hazards for tire blowouts at high speeds. Additionally, promptly remove pebbles stuck in the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that may deteriorate rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water to cool down. In hot weather or during high-speed driving, tires can overheat, increasing air pressure. In such cases, stop to let the tires cool naturally. Never release air to reduce pressure or splash water to cool down, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Minimize frequent and hard braking to prevent accelerated tread wear from dragging on the ground.
