215 75r15 In Inches tire size – Detailed Analysis

When analyzing this tire size, you’ve got to think about its width, aspect ratio, radial construction, diameter, and so on.

It’s important to look at the various specifications of the 215 75r15 tire size when analyzing its performance and compatibility with a particular vehicle. For safe and efficient driving, you need good tires.

Sidewall Height

Tire sidewall height is how far the tire rim is from the outermost part of the sidewall. Usually measured in millimeters or inches, it’s determined by the aspect ratio of the tire.

It affects how well a tire performs and how well it handles because of the sidewall height. 215 75r15 tires have a sidewall height of approximately 6.35 inches.

Overall tire diameter 

In tire metric terms, tire diameter is the distance between the tire tread top and bottom. In addition to speedometer accuracy, vehicle handling, and ground clearance, tire diameter affects a lot of other aspects of tire performance.

The overall tire diameter of a 215 75r15 tire size is approximately 27.7 inches or 703.58 millimeters.

Tire Type 

Look on the sidewall of your tire for the numbers and letters. You should find a sequence that looks like “P215 75r15”. The first letter in this sequence represents the type of tire you have.

P stands for passenger, which means the tires have been inspected according to passenger car safety standards. The same will apply to all four tires.

Tire Section Width

It is the measurement of the width of the tire from sidewall to sidewall. The first three figures of tire size indicate the width of the tire. For example, a 215/75 r15 in inches tire has a width of 215 millimeters or 8.46 inches.


The circumference of a tire is the distance around the outer edge of the tire, usually measured in inches or millimeters. Therefore, a tire of size 215 75r15 has an approximate circumference of 87.1 inches. It also refers to the distance a tire travels in one complete rotation.


The radius is typically expressed in inches or millimeters and is one of the most important measurements used to describe a tire. This distance can be calculated by measuring the distance between a tire’s center and its outer edge.

It is necessary to measure the radius of the tire in order to determine the tire size and rolling distance. 215 75r15 in inches tires have a radius of 13.85 inches. 

Rim Diameter

Rim diameter is also referred to as wheel diameter. It is the size of the wheel, measured from one end to the other, that is displayed in the tire size.

This information indicates the size of the wheel the tire is intended to fit. For example, the size 215/75 R15 tire is designed to fit a 15″ wheel.

Rim Width Range

Depending on the tire size, the rim width range determines what rim width is acceptable. When choosing a tire for your vehicle, it is important to consider the tire rim width range specified by the manufacturer.

For the 215 75r15 in inches tire, the recommended rim width ranges from 5.5” to 7.5″ inches. Fitment and safety are dependent on matching the tire’s recommended rim width range to that of the wheel it will be mounted on.


There is a way to identify the radial construction of a tire by its tire size (R). The letter “R” or “r” in that tire size indicates Radial, which signifies that the layers of the tire are arranged in a radial pattern.
