Wheel & Tire Fitment Visualizer

Need help finding what wheels and tires are going to fit your car? Our Fitment Visualizer compares your current sizing to the setup you want and shows the changes in real time. Dial in your width, offset, diameter, and even tire size so you know your fitment is clean before you click add to cart. Mod smarter, not harder.

Note: Results will vary. When measuring fitment on your vehicle, the suspension needs to be compressed, as suspension travel changes how the wheel and tire fit in the fender. The suspension shown in this diagram is for visual reference only and does not represent actual clearance.

Fitment Comparison

Here's what's changing: Your new setup will be 0.74" taller overall, which means your ride height will increase by 0.37". The outer edge of the wheel will stick out 0.89"more compared to your current setup, and the inner edge will sit 0.11" closer to your suspension. Your speedometer will read 2.9% slower than your actual speed. Keep in mind that these are approximate values and most tire manufacturers vary slightly in their measurements.
