The 43mm Rubber Wheel Tyre for N20 Gear Motor is engineered specifically for ultra-compact mobile robot platforms. Designed to mate directly onto the $3\text{mm}$ D-profile output shaft of N20 micro metal gearboxes, this wheel eliminates the need for bulky shaft adapters or set-screw couplers.

The central hub is injection-molded from lightweight, durable ABS plastic and fitted with a high-friction synthetic rubber tire. The grooved outer tread ensures reliable grip on polished surfaces, acrylic test tracks, and desktop environments. Its small outer diameter ($43\text{mm}$) provides excellent torque transfer and high precision control for mini sumo competitions, maze-solving robots, and desktop rovers.

Key Features and Benefits

• Direct Press-Fit for N20 Shafts: Features a precision-molded $3\text{mm}$ D-hole hub that slides securely onto N20, N30, and GA12-N20 micro gear motor shafts.

• High-Traction Synthetic Rubber Tread: Textured outer tyre prevents wheel slipping during rapid acceleration and braking.

• Low-Profile & Lightweight Design: Weighing only 12 grams, it minimizes total weight and strain on micro gearbox gear trains.

• Durable Polymer Center Hub: Resists wear and deformation around the motor shaft mounting socket.

• Compact $43\text{mm}$ Form Factor: Perfect for space-constrained micro-robot chassis where larger $65\text{mm}$ wheels won't fit.
