About This Calculator

Staggered tire fitment means using different tire sizes on the front and rear axles, common in performance and rear-wheel-drive vehicles for handling or aesthetic reasons. While the width and rim diameter might differ, it's critical that the **overall diameter** (or rolling circumference) of the front and rear tires remains very close, especially for All-Wheel Drive (AWD) and Four-Wheel Drive (4WD) vehicles. Significant differences in overall diameter between front and rear tires on an AWD/4WD vehicle can cause the system to bind, leading to excessive wear or even damage to the differentials, transfer case, and other drivetrain components. It can also interfere with Anti-lock Braking Systems (ABS) and traction/stability control systems. Most manufacturers recommend keeping the diameter difference within 1-3%. This calculator helps you compare the overall diameters of two P-Metric tire sizes (one for the front, one for the rear) and clearly shows the percentage difference, allowing you to make informed decisions about your staggered setup.

How to Use This Calculator
  1. Enter the P-Metric specifications for your Front Tires: Width (mm), Aspect Ratio (%), and Rim Diameter (inches).
  2. Enter the P-Metric specifications for your Rear Tires using the same units.
  3. Click the "Calculate Differences" button.
  4. The results will display the overall diameter for both front and rear tires, the absolute difference in millimeters and inches, and the percentage difference.
  5. Pay close attention to the percentage difference and any warnings, especially if your vehicle is AWD or 4WD. A warning will be shown if the difference exceeds a typical tolerance (e.g., 3%).
