Technical Disclaimer

GIIRR outputs are theoretical calculations, not measurements or safety certifications.

Actual RPM, speed, torque, chain length, belt speed and tire behavior can differ because of slip, deflection, wear, tolerances, control systems, tire load and other real-world factors.

Before acting on a result

Verify critical values against manufacturer documentation, applicable regulations and physical measurement. For safety-critical machinery, vehicle modifications or high-speed rotating equipment, use a qualified professional.
