Truck Wheel & Tire Fitment Visualizer

Compare your current wheels and tires to the setup you want and watch the fitment change as you type. Adjust offset, wheel width, diameter, and tire size in metric or standard, then see how much the new combo pokes, tucks, or sits compared to stock before you buy.

Want to run a stretched setup? We can show that too.

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 brake and hub in the image are for visual reference only and do not represent actual clearance.

Fitment Comparison

Here's what's changing: Your new setup will be 2.36" taller overall, which means your ride height will increase by 1.18". The outer edge of the wheel will stick out 1.68" more compared to your current setup, and the inner edge will sit 0.68" further away from your suspension. Your speedometer will read 7.2% slower than your actual speed. Keep in mind that these are approximate values and most tire manufacturers vary slightly in their measurements.
