Custom Offsets Tire Size Comparison Tool: Visualize Your Rubber On Your Truck

When you are shopping for tires, the numbers printed on the sidewall—like 275/60R20—can be deceptive. A "275" is the width in millimeters, but the "60" is a percentage of that width, which determines the height of the sidewall. Because of this ratio, a small change in width can surprisingly alter the height of your tire, throwing off your speedometer and your aesthetic.

Overwhelmed yet? Don't worry. The Custom Offsets Tire Size Comparison Tool cuts through the confusion. This tool allows you to go head-to-head with two different tire sizes to see exactly how they stack up against each other. Are you debating between a 33-inch all-terrain and a 35-inch mud-terrain? Do you want to know if stepping up from a 285/65 to a 305/55 will make your truck look wider or taller?

Input the width, aspect ratio, and wheel diameter for both tires, and we will generate a direct comparison. We analyze the Overall Diameter, Section Width, and Sidewall Height.

This data is crucial for more than just looks. A significantly taller tire will affect your speedometer accuracy (reading slower than you are actually traveling) and may require a lift kit or leveling kit to clear the wheel well. A wider tire might require a different wheel offset to prevent rubbing on the frame.

Stop guessing what "33s" look like compared to stock. Use the data to visualize the meat on your wheels and ensure you’re filling out your fender wells exactly how you intended.
