19565R15

195/65R15 (often written as 19565R15) is a common tire size used on many passenger cars. It is a standard designation that communicates the tire’s dimensions and construction. The size is normally found on the tire sidewall and on vehicle placards.

The first number, 195, represents the tire width in millimeters from sidewall to sidewall. The 65 is the aspect ratio, indicating the tire’s height is 65% of its width. The letter R denotes radial construction, the most common type for modern tires. The final 15 is the diameter of the wheel in inches that the tire is designed to fit.

This size provides a balance between ride comfort and handling and is frequently fitted to compact and some mid-size cars, particularly in regions where 15-inch wheels are common. Actual performance depends on the specific tire model, including tread design and the load index and speed rating printed on the sidewall (for example, 91V or 88T).

When replacing tires, it is important to use a size that matches or closely matches the vehicle’s specifications as listed in the owner's manual or on the door placard. Ensure compatible rim width, commonly around 5.5 to 6.5 inches for this size, and consider the tire’s load rating, speed rating, and intended season (all-season, winter, or summer). Do not mix significantly different overall diameters on the same axle, as this can affect vehicle dynamics and instrumentation. Related sizes such as 195/60R15 or 205/65R15 are nearby alternatives but alter circumference and ride characteristics.
