Our Engineering Mission

About Tire Size Checker

Building the most accurate, visually intuitive, and responsive tire dimension intelligence platform for drivers and enthusiasts.

Why We Built TireSizeChecker.com

Legacy tire calculators are cluttered, slow, and overly simplistic. We created TireSizeChecker.com to offer drivers, automotive mechanics, track enthusiasts, and off-road builders a clean, instant, and technically accurate platform with proportional 2D CAD visual rendering and comprehensive variance metrics.

Our Calculation Engine Standards

All calculations are grounded in standard tire engineering mathematics conforming to Tire and Rim Association (TRA) and ETRTO dimension formulas:

Overall Diameter (D): D = (2 × Width × Aspect Ratio / 100) + Rim
Circumference (C): C = π × Overall Diameter
