What is P315/35R20 in inches?
When we convert P315/35R20 to inches, it is equivalent to 28.7x12.4R20 tire size in the high flotation system. P315/35R20 tires have a diameter of 28.7" (728 mm), a tread width of 12.4" (315 mm), and can be mounted on a wheel with a diameter of 20" (508 mm). The sidewall of the tire is 4.3" (110 mm), and the tire's circumference is 90.1" (2286 mm). This means a P315/35R20 tire will make 703 revolutions per mile, or 437 revolutions per kilometer.

How to read P315/35R20 tire size?
Reading a tire size such as can be broken down into three main parts: tread width, aspect ratio and rim diameter.
315 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 315 millimeters wide.
35 represents the height of the tire's cross-section as a percentage of its width. It means the height is 35% of the tire's width.
R denotes that tire has radial construction.
20 is the diameter of the wheel that the tire fits on, measured in inches. This tire would fit on a 20-inch wheel.
How to convert P315/35R20 to inches
The P315/35R20 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 315 mm by 25.4, yielding a tire width of approximately 12.4 inches. To find the sidewall height in inches, you calculate 35% of the tire width in millimeters (315 mm), convert this figure to inches as before, resulting in a sidewall height of about 4.3 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 (20 inches), giving you an overall tire diameter of approximately 28.7 inches.
So, when converted to inches, P315/35R20 tire is 12.4 inches wide, 28.7 inches tall, and fits 20-inch rims.
How wide is a P315/35R20 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. P315/35R20 tire has a width of 12.4 inches or 315 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 P315/35R20 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. P315/35R20 tire has a diameter or height of 28.7 inches or 728 mm.

P315/35R20 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. P315/35R20 tire has a sidewall height of 4.3 inches or 110 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 P315/35R20 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. P315/35R20 tire can be mounted on 20-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.

P315/35R20 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. P315/35R20 tire has a circumference of 90.1 inches or 2286 mm.

How many revolutions does a P315/35R20 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. P315/35R20 tire completes 703 revolutions per mile or 437 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.
