Enter the front and rear tire widths, aspect ratios, and wheel diameter into the calculator to determine the stagger of your tires. This calculator helps in setting up a staggered tire configuration for vehicles.
Staggered Tire Formula
The following formula is used to calculate the stagger of tires:
S = (RW * RA / 100 * 2 / 25.4 + WD) - (FW * FA / 100 * 2 / 25.4 + WD)
Variables:
- S is the stagger (mm)
- RW is the rear tire width (mm)
- RA is the rear aspect ratio (%)
- FW is the front tire width (mm)
- FA is the front aspect ratio (%)
- WD is the wheel diameter (inches)
To calculate the stagger, subtract the front tire diameter from the rear tire diameter. The tire diameter is calculated by multiplying the tire width by the aspect ratio, then by 2, dividing by 25.4 (to convert from mm to inches), and finally adding the wheel diameter.
What is Staggered Tire Configuration?
A staggered tire configuration is when the rear tires are wider or have a different diameter than the front tires. This setup is often used in performance vehicles to improve traction and handling, especially during acceleration and cornering. The stagger is the difference in diameter between the front and rear tires.
How to Calculate Stagger?
The following steps outline how to calculate the stagger of tires:
- First, determine the rear tire width (RW) in millimeters.
- Next, determine the rear aspect ratio (RA) as a percentage.
- Then, determine the front tire width (FW) in millimeters.
- After that, determine the front aspect ratio (FA) as a percentage.
- Next, determine the wheel diameter (WD) in inches.
- Use the formula to calculate the stagger (S).
- Finally, compare the calculated stagger with the desired setup for your vehicle.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Rear tire width (RW) = 275 mm
Rear aspect ratio (RA) = 35 %
Front tire width (FW) = 245 mm
Front aspect ratio (FA) = 40 %
Wheel diameter (WD) = 19 inches
