Frequently Asked Questions
The main difference between the two given tire sizes is the difference between their sidewall heights. In both cases, we have a tire that is designed with 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,” meaning the type of the tire; and 15 is the size of the rim in inches.
No, it will not fit properly. The numbers 195 and 185 refer to the respective tread widths of the two types of tires since the first number is in mm. Therefore, the tire 185/65R15, has a smaller tread width. On the other hand, 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. Hence, a 195/60R15 tire is wider but shorter than an 185/65R15 tire.
