The 85mm Large Robot Smart Car Wheel is engineered for high-performance mobile robotics applications that demand superior traction, higher ground clearance, and rugged durability. Featuring an eye-catching metallic blue ABS polymer rim fitted with a thick, treaded natural rubber tyre, this wheel easily traverses rough surfaces, carpet, grass, and incline ramps.

At $85\text{mm}$ in diameter and $38\text{mm}$ in width, it offers significantly greater contact surface and damping compared to standard $65\text{mm}$ acrylic smart car wheels. The reinforced internal hub features a standard $12\text{mm}$ hex socket, allowing secure attachment to various motor shaft diameters using brass or aluminum hex adapters—preventing shaft slipping under heavy loads and high motor torque.

Key Features and Benefits

• Extra-Wide $38\text{mm}$ Profile: Enhances lateral stability and weight distribution across multi-wheel drive chassis.

• Deep Tread Rubber Tyre: Flexible high-friction rubber tread grips smooth tiles, wood floors, and outdoor terrain without slipping.

• Sturdy ABS Rim Construction: Lightweight yet tough blue polymer hub resists impacts and structural stresses during high-speed movement.

• Universal $12\text{mm}$ Hex Hub Mounting: Easily adapts to 2WD/4WD/6WD robot platforms using $12\text{mm}$ brass hex adapters ($3\text{mm},4\text{mm},5\text{mm},6\text{mm}$ shaft sizes).

• Increased Ground Clearance: $85\text{mm}$ diameter helps mobile robots clear small rocks, doorstep transitions, and wiring runs.
