Switching to tires with a 55% aspect ratio provides more comfort because tires with higher smoothness have longer sidewalls and stronger cushioning capacity, making them relatively more comfortable. However, the road feel may be poorer, and the lateral resistance during turns is weaker. Conversely, tires with a low aspect ratio and large inner diameter have shorter sidewalls and wider treads, resulting in a larger contact area and greater pressure-bearing capacity. These tires are more responsive to road conditions, offering stronger lateral resistance during turns and enhanced vehicle handling. Regardless of the type of tires you switch to, the following points should be noted during daily use: Regularly inspect 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 vehicle's performance. Small cracks may also pose a risk of tire blowouts at high speeds. Additionally, promptly remove pebbles lodged in the grooves. Try to park on level ground. 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 the tires. In hot weather or during high-speed driving, tires are prone to overheating, and the air pressure may increase. In such cases, stop to allow the tires to cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this may cause abnormal aging of the tread rubber. Avoid sudden braking. Minimize frequent or hard braking to prevent accelerated tread wear caused by dragging between the tires and the road.
