Enter the total weight of the rider and the bicycle and the tire radius into the calculator to determine the optimal tire pressure. This calculator can also evaluate any of the variables given the others are known.

## Cycling Tire Pressure Formula

The following formula is used to calculate the optimal tire pressure for cycling.

TP = (W * R) / (200 * V)

Variables:

• TP is the optimal tire pressure (psi) W is the total weight of the rider and the bicycle (lbs) R is the tire radius (inches) V is the tire volume (cubic inches)

To calculate the optimal tire pressure for cycling, multiply the total weight of the rider and the bicycle by the tire radius. Then divide the result by the product of 200 and the tire volume.

## What is a Cycling Tire Pressure?

Cycling tire pressure refers to the amount of air pressure, typically measured in pounds per square inch (PSI), that is maintained within the tires of a bicycle. The correct tire pressure can greatly influence the performance, comfort, and safety of a cyclist. It can affect the bike’s speed, traction, and susceptibility to flats. The ideal tire pressure varies depending on factors such as the type of bike, the weight of the rider, the tire size, and the riding conditions.

## How to Calculate Cycling Tire Pressure?

The following steps outline how to calculate the Cycling Tire Pressure using the given formula:

1. First, determine the total weight of the rider and the bicycle (W) in pounds.
2. Next, determine the tire radius (R) in inches.
3. Next, determine the tire volume (V) in cubic inches.
4. Next, gather the formula from above = TP = (W * R) / (200 * V).
5. Finally, calculate the Cycling Tire Pressure (TP).
6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge:

Total weight of the rider and the bicycle (W) = 150 lbs

Tire radius (R) = 12 inches

Tire volume (V) = 100 cubic inches
