85MM Large Robot Smart Car Wheel, 38MM Width Surface Blue Rim

85mm Large Robot Smart Car Wheel – 38mm Wide Blue Rim

The 85mm Large Robot Smart Car Wheel is a heavy-duty traction wheel built for medium-to-large robotic platforms and DIY smart cars. It pairs a high-strength reinforced nylon rim in electric blue with a high-grip black rubber tire, keeping your robot stable and fast across smooth, dusty, or rough surfaces.

Unlike standard hobby wheels, the tire features an internal sponge liner that maintains its shape and boosts load capacity under heavier chassis. The upgraded deep-groove tread pattern increases friction and reduces slippage, while the extra-wide 38mm profile gives a stable footprint for 4WD/6WD platforms carrying sensors, batteries, and payloads. The reinforced nylon hub resists cracking and impact, making it well suited for combat bots and outdoor rovers.

Features

• Large 85mm diameter clears small obstacles and uneven terrain
• Extra-wide 38mm surface for a stable footprint under heavy loads
• Sponge-lined rubber tire — internal foam support maintains tire shape and increases load capacity
• Reinforced nylon hub with high strength-to-weight ratio, resistant to cracking and impact
• Upgraded deep-groove tread pattern for maximum traction and minimal slippage
• Optimized hub design for efficient power transfer with high-torque motors
• Professional black-on-blue color scheme

Applications

• Heavy-duty 4WD / 6WD smart car platforms
• Search and rescue robots navigating obstacles and debris
• Autonomous delivery bots carrying payloads
• Competition and combat robotics requiring grip and pushing power
• Outdoor and all-terrain DIY robotic projects

Package Includes

• 1 × 85mm Large Robot Smart Car Wheel (Blue Rim)

Usage Note: Motor coupling is not included. This wheel requires a hexagonal coupling to mount on standard motor shafts — choose the correct hex adapter for your motor shaft size (e.g., 4mm, 5mm, or 6mm) for a secure fit.
