Rolling Radius of Tire Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rolling Radius of Tire = 2/3*Geometrical Radius of Tire+1/3*Loaded Height of Tire
R_w = 2/3*R_g+1/3*R_h
This formula uses 3 Variables

Variables Used

Rolling Radius of Tire - (Measured in Meter) - Rolling Radius of Tire is the distance from the center of the wheel to the point of contact with the road, affecting tire behavior in racing cars.
Geometrical Radius of Tire - (Measured in Meter) - Geometrical Radius of Tire is the distance from the center of the wheel to the outer circumference of the tire, affecting the racing car's performance and handling.
Loaded Height of Tire - (Measured in Meter) - Loaded Height of Tire is the vertical distance from the road surface to the center of the tire when the tire is subjected to load in a racing car.

STEP 1: Convert Input(s) to Base Unit

Geometrical Radius of Tire: 0.45 Meter --> 0.45 Meter No Conversion Required
Loaded Height of Tire: 0.35 Meter --> 0.35 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_w = 2/3*R_g+1/3*R_h --> 2/3*0.45+1/3*0.35

Evaluating ... ...

R_w = 0.416666666666667

STEP 3: Convert Result to Output's Unit

0.416666666666667 Meter --> No Conversion Required

FINAL ANSWER

0.416666666666667 ≈ 0.416667 Meter <-- Rolling Radius of Tire

What is Rolling Radius of a Tire?

The rolling radius of a tire is the distance between the center of the wheel and the bottom of the tire. Typically, the larger the diameter of the tire, the greater the rolling radius. Understanding this is important for designers of vehicles since this will impact the vehicle's functions, such as the speedometer, the transmission shift points and the Revolutions Per Minute (RPM) of the engine's crank shaft.

How to Calculate Rolling Radius of Tire?

Rolling Radius of Tire calculator uses Rolling Radius of Tire = 2/3*Geometrical Radius of Tire+1/3*Loaded Height of Tire to calculate the Rolling Radius of Tire, Rolling Radius of Tire formula is defined as a measure of the effective radius of a tire in contact with the road, which affects the vehicle's overall performance, fuel efficiency, and handling, and is a critical parameter in the design and development of vehicles. Rolling Radius of Tire is denoted by R_w symbol.

How to calculate Rolling Radius of Tire using this online calculator? To use this online calculator for Rolling Radius of Tire, enter Geometrical Radius of Tire (R_g) & Loaded Height of Tire (R_h) and hit the calculate button. Here is how the Rolling Radius of Tire calculation can be explained with given input values -> 0.416667 = 2/3*0.45+1/3*0.35.
