NanoTire

NanoTire is a professional-grade tire size calculator, wheel fitment visualizer, and automotive telemetry tool designed for car enthusiasts, mechanics, and track drivers.

Whether you are upgrading to aftermarket rims, calculating tire stretch and aspect ratios, checking suspension clearance, or correcting speedometer error, NanoTire provides mathematical precision and real-time interactive 2D and 3D visual geometry.

✨ KEY FEATURES

📐 Comprehensive Dual Tire Specification Comparison
• Compare stock vs new tire sizes instantly with side-by-side technical telemetry.
• Computes total diameter, sidewall height, section width, circumference, and revolutions per mile/kilometer.
• Visual diameter percentage delta indicator with instant safety threshold warnings (±3% rule).
• Calculates ride height and ground clearance changes down to fractions of a millimeter or inch.

🔍 2D Cross-Section & 3D Interactive Rim Geometry
• Real-time coaxial overlay: Inspect tire profile, sidewall angle, and rim width relationships visually.
• 2D section view displays exact contact patch width and wheel arch clearance.
• Interactive 3D viewpoint allows 360-degree rotation and close-up inspection of tire tread and wheel proportions.

🏎️ Speedometer Calibration & Error Delta
• Precise speed calibration across the full velocity curve.
• See true vehicle speed when the speedometer indicates 100 km/h or 60 mph.
• Dynamic speed delta card displays odometer mileage discrepancies and real-time speed shifts.

⚙️ Wheel Offset (ET) & Suspension Clearance
• Compare rim width (J) and offset (ET) changes between setups.
• Calculates suspension inner strut clearance and outer fender flush/poke extension.
• Helps prevent inner wheel rubbing against coilovers or outer fender arch contact.

🚗 Multi-Vehicle Garage & Setup Management
• Save custom wheel and tire combinations for your garage vehicles.
• Quick-switch between setups for summer, winter, and track-day configurations.
• Generate detailed fitment reports ready to share with friends or your tire shop.

📷 Virtual Wheel Try-On & Visual Studio
