About Us

The Tacoma Tire Calculator exists because Toyota Tacoma owners, whether stock or modified, often face the same question: “Will these tires fit my truck?”

I wanted a calculator that makes the answer immediately obvious. Enter your stock tire size and your desired new tire size. The calculator instantly shows the size difference, speedometer error, and potential clearance issues—so you can choose the right tires for your build, avoid rubbing, and understand the impact on your truck's performance.

What we care about

Accuracy first. Calculations are based on standard tire sizing formulas to provide reliable comparisons.
Privacy by default. No login or account is required to use the tool.
Speed & clarity. The interface is clean, fast, and mobile-friendly—use it while shopping for tires or planning your build.
Accessibility. Clear typography, easy input fields, and keyboard navigation support.

Friendly reminders

This is a calculation and planning tool—not a substitute for professional fitment advice or a test fit.
Always consider your specific lift, wheel offset, and wheel backspacing, as these dramatically affect clearance. Tire brand measurements can also vary slightly.
