Frequently Asked Questions
The main difference between these two tire sizes is their sidewall heights. Both have a tread width of 195 millimeters and a diameter of 15 inches, However, while the 195/60R15 type features a standard sidewall height that is 60% of the tread width, the 195/65R15 type has a taller, 65-inch sidewall.
The optimal air pressure for these tires can vary due to the size of the vehicle, the weight of the load, and the tire manufacturer’s guidelines. However, the general air pressure for this type of tire is usually between 30-35 PSI when cold.
This is the tire size information. Each part of this number means the following: 195 is the tread width of the tire in millimeters; 60 refers to the aspect ratio or the tire’s sidewall height as a percentage of the width. In this case, the height of the side is 60% of 195 mm, R is for “Radial,” and 15 is the size of the rim in inches.
No, it will not fit properly. The numbers 195 and 185 refer to the tread widths of the two tires in mm and the 185/65R15 tire has a smaller tread width. The second set of numbers refers to the sidewall, and the 65 and 60 numbers cause the difference between 65 and 60% of the 195 mm, which makes the second tire taller. A 195/60R15 tire is wider but shorter than a 185/65R15 tire.
