1. What Is Stagger?

Stagger refers to the difference in tire sizes between the front and rear axles of a vehicle. It's commonly used in performance and racing vehicles to optimize handling characteristics.

2. How Stagger Is Calculated

The stagger is calculated using a simple formula:

Where:

• Front Tire Size — Diameter or width of front tires (mm)
• Rear Tire Size — Diameter or width of rear tires (mm)

Explanation: Positive stagger means front tires are larger than rear tires, while negative stagger means rear tires are larger.

3. Importance of Stagger Calculation

Details: Proper stagger affects vehicle handling, cornering performance, and tire wear. It's particularly important in oval track racing where it helps the car turn left more efficiently.

4. Using the Calculator

Tips: Enter the front and rear tire sizes in millimeters. The calculator will show the difference between them. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for tire sizes?
A: This calculator uses millimeters (mm) for consistency, but you can convert from inches if needed (1 inch = 25.4 mm).

Q2: What's a typical stagger value?
A: For oval track racing, stagger typically ranges from 0.5 to 1.5 inches (12-38 mm), depending on track size and banking.

Q3: Does stagger affect all vehicles the same way?
A: No, front-wheel drive, rear-wheel drive, and all-wheel drive vehicles respond differently to stagger due to their different drivetrain configurations.

Q4: Can I use this for diameter and width measurements?
A: Yes, this calculator works for both diameter and width measurements, but be consistent in which dimension you're measuring.

Q5: How often should I check my stagger?
A: Competitive racers often check stagger before each race, as even small changes can affect handling.
