## Description

Calculate vehicle speed, engine RPM, gear ratios, final drive & tire sizes with precision. Compare setups & visualize speeds across all gears.

Gear Ratio & Speed Calculator is the ultimate automotive engineering tool for car enthusiasts, track racers, off-road builders, and gearheads.

Calculate precise relationships between engine RPM, vehicle speed, transmission gear ratios, final drive ratios, and tire dimensions.

Key Features:
• RPM to Speed Calculator: Accurately calculate vehicle speed from engine RPM, gear ratio, and tire size.
• Speed to RPM Calculator: Determine the exact RPM required for target cruising or highway speeds.
• Gear Speed Matrix Table: Full-spectrum speed table across all gears and RPM intervals.
• Tire Size Calculator: Metric (e.g. 265/70R17) and Inch flotation (e.g. 33x12.50R17) conversions and diameter calculations.
• Setup Comparison: Side-by-side comparison for tire upgrades and ring & pinion gear changes.
• Vehicle Garage Profiles: Save and switch between multiple car configurations instantly.
• Unit Support: Seamless toggle between Metric (km/h, mm) and Imperial (mph, inches).
