What is 155R12C in inches?
When we convert 155R12C to inches, it is equivalent to 22x6.1R12 tire size in the high flotation system. 155R12C tires have a diameter of 22" (559 mm), a tread width of 6.1" (155 mm), and can be mounted on a wheel with a diameter of 12" (305 mm). The sidewall of the tire is 5" (127 mm), and the tire's circumference is 69.1" (1755 mm). This means a 155R12C tire will make 917 revolutions per mile, or 570 revolutions per kilometer.

How to read 155R12C tire size?
Reading a tire size such as can be broken down into three main parts: tread width, aspect ratio and rim diameter.
155 is the width of the tire in millimeters from sidewall to sidewall when it's fully inflated and not under any load. In this example, the tire is 155 millimeters wide.
82 represents the height of the tire's cross-section as a percentage of its width. It means the height is 82% of the tire's width.
R denotes that tire has radial construction.
12 is the diameter of the wheel that the tire fits on, measured in inches. This tire would fit on a 12-inch wheel.
How to convert 155R12C to inches
The 155R12C conversion is very simple. There are 25.4 millimeters in an inch. All we have to do is divide tread width and sidewall height by 25.4 to convert to inches.
To convert the tire width to inches, you divide 155 mm by 25.4, yielding a tire width of approximately 6.1 inches. To find the sidewall height in inches, you calculate 82% of the tire width in millimeters (155 mm), convert this figure to inches as before, resulting in a sidewall height of about 5 inches. However, to understand the tire's overall diameter, you need to consider the height of two sidewalls and the diameter of the wheel it fits. Therefore, you multiply the sidewall height by 2 and add the wheel diameter (12 inches), giving you an overall tire diameter of approximately 22 inches.
So, when converted to inches, 155R12C tire is 6.1 inches wide, 22 inches tall, and fits 12-inch rims.
How wide is a 155R12C tire?
Tire width, also known as section width, is a measurement in millimeters that indicates the width of a tire from one sidewall to the other. It is the first number provided in a tire's size specifications. 155R12C tire has a width of 6.1 inches or 155 mm.
A greater tire width can increase the tire's contact patch with the road, potentially improving grip and handling. However, wider tires can also increase rolling resistance, which could negatively impact fuel efficiency.
How tall is a 155R12C tire?
Tire height, also known as the tire's diameter or overall diameter, is the measurement from the ground to the top of the tire. It's essentially the distance from one side of the tire to the other, passing through the center, when it's correctly inflated and not under load. 155R12C tire has a diameter or height of 22 inches or 559 mm.
155R12C Tire Sidewall Height
Tire sidewall height, also known as the tire's aspect ratio, is the measurement of the height of the tire's cross-section or the height of the tire from the rim to the tread. It is typically represented as a percentage of the tire's width. 155R12C tire has a sidewall height of 5 inches or 127 mm.
Sidewall height (also known as tire profile) can greatly affect a tire's driving characteristics. Lower profile tires (30 or 35 series) often provide better handling but can give a harsher ride, while higher profile tires (65 or 70 series) generally provide a smoother ride but with less precise handling.
What size rim fits a 155R12C tire?
The rim diameter refers to the diameter of the wheel on which a tire is mounted. It is the distance from one edge of the rim to the opposite edge, passing through the center of the wheel. 155R12C tire can be mounted on 12-inch wheels.
The rim diameter is crucial not only for fitting the tire properly but also plays a role in determining the overall performance of the vehicle, including its handling and ride quality.
155R12C Tire Circumference
Tire circumference refers to the distance around the outer edge of a tire. It is the measurement of the entire circumference or perimeter of the tire when it is inflated and mounted on a wheel. 155R12C tire has a circumference of 69.1 inches or 1755 mm.
How many revolutions does a 155R12C tire make?
Tire revolutions refer to the number of complete rotations a tire makes while the vehicle is in motion. It is a measure of the distance covered by the tire. 155R12C tire completes 917 revolutions per mile or 570 revolutions per kilometer.
Tire revolutions are often used in various calculations related to vehicle dynamics, such as determining the distance traveled, estimating fuel consumption, or calculating the speed of the vehicle based on the rotation of the tires. Tire revolutions can also be tracked or monitored by certain vehicle systems, such as the anti-lock braking system (ABS) or the vehicle's onboard computer, for various purposes.
