Enter the tire diameter and gear ratio into the calculator to determine the tire rollout. This calculator helps in understanding how far a vehicle will travel with one revolution of the tire.
Tire Rollout Formula
The following formula is used to calculate the tire rollout.
Rollout = π * Tire Diameter / Gear Ratio
Variables:
- Rollout is the distance a vehicle travels with one revolution of the tire (inches).
- Tire Diameter is the diameter of the tire (inches).
- Gear Ratio is the ratio of the gears connected to the tire.
To calculate the tire rollout, divide the product of pi and the tire diameter by the gear ratio.
What is Tire Rollout?
Tire rollout, also known as tire circumference, is the distance a vehicle travels in one complete revolution of the tire. It is an important measurement for racers and car enthusiasts to optimize performance, as it affects the vehicle’s acceleration, speed, and gearing. The rollout can vary based on tire size, pressure, and wear, so it is important to calculate it accurately for the best vehicle setup.
How to Calculate Tire Rollout?
The following steps outline how to calculate the Tire Rollout.
- First, measure the diameter of the tire (in inches).
- Next, determine the gear ratio of the gears connected to the tire.
- Use the formula Rollout = π * Tire Diameter / Gear Ratio.
- Finally, calculate the Tire Rollout (in inches).
- 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.
Tire Diameter = 26 inches
Gear Ratio = 3.5
