✅ Tire diameter, sidewall height, and circumference
✅ Speedometer error when changing tire sizes
✅ Difference between stock and new tires
✅ Compatibility with rims and suspension clearance

💡 Features:

Supports both metric and imperial tire sizes
Easy comparison of old vs. new tire dimensions
Shows speed difference when switching tires
Useful for mechanics, car enthusiasts, and daily drivers

👤 Who Should Use This:

📌 Car owners checking tire replacements

Tire size affects handling, fuel efficiency, comfort, and speedometer accuracy.

205 = tire width (mm), 55 = aspect ratio (sidewall height as % of width), R = radial construction, 16 = rim diameter (inches).

The speedometer may show a slower speed than actual, and clearance issues may occur.

It is the ratio of the sidewall height to the tire width, expressed as a percentage.

The distance a tire covers in one complete revolution, important for speed and mileage calculations.
