What does the tire specification 18560r15 mean?

The tire specification 18560r15 indicates a cross-sectional width of 185mm, an aspect ratio of 60, 'r' stands for radial tire, and '15' means the tire can be mounted on a 15-inch rim. Tires are circular elastic rubber products installed on metal rims, designed to support the vehicle body, absorb external shocks, maintain contact with the road surface, and ensure driving performance. The method to check car tire pressure is: 1. Unscrew the tire valve cap; 2. Press the tire pressure gauge onto the valve; 3. Push the gauge all the way down; 4. Observe the pointer and read the measured tire pressure value.
When I see the code 185/60R15 on a tire, it seems quite simple: 185 represents the tire width of 185 millimeters, which affects grip and stability; 60 is the aspect ratio, meaning the tire height is 60% of the width, influencing ride comfort; R stands for Radial construction, the most common tire type today, providing a smoother drive; 15 refers to the 15-inch wheel diameter, matching specific rim sizes. Understanding these is crucial for new drivers as it relates to driving safety and vehicle performance. Incorrect sizing, such as mismatched width, can easily lead to skidding or increased fuel consumption, so always refer to the car manual or consult an expert when changing tires. Regular tire inspections can make long trips more reassuring, and I always pay attention to these details while driving to avoid accidents.
