What does 185/65r14 mean?

[GiselleFitz]

185/65r14 indicates that the tire width is 185cm, 65 represents the aspect ratio of the tire at 65%, and r14 means the tire size is 14 inches, which is a radial tire without an inner tube. Tires from different brands can be replaced if the parameters are the same, but it's also necessary to check whether the tread patterns are identical. If the patterns are the same, the grip and balance will not be affected after replacement. Tires are circular elastic rubber products mounted on various vehicles or machinery for rolling on the ground. They are usually installed on metal rims to support the vehicle body, absorb external shocks, maintain contact with the road surface, and ensure the vehicle's driving performance.
