Practical Example

Imagine your car currently has 26-inch tires, and you’re considering upgrading to 28-inch tires.

• Step 1: Enter 26 as the old tire diameter.
• Step 2: Enter 28 as the new tire diameter.
• Step 3: Click Calculate.

The results show:

• Diameter Difference: 2 in
• Percentage Difference: 7.69%

This means your new tires are 2 inches larger than the old ones, which corresponds to nearly an 8% increase in overall tire diameter. This information helps you evaluate whether the change is acceptable for your vehicle, speedometer calibration, or handling characteristics.
