Wheel-Size is the most complete automotive wheel fitting and performance tracking app available. Our new interface was designed with you in mind and was inspired by our best-selling website.

Enter the details of your vehicle to look up the correct wheel size and performance data, including your vehicle’s speed, acceleration, and fuel economy, as well as tire size, ride comfort, and road grip.

The app allows you to compare different tires and wheel sizes with your vehicle by simply entering its details. This way, you can use the app to get an idea of how your vehicle would handle and perform in different sizes.
