2X38MM Small Rubber Tires Wide Wheel

2 × 38mm Small Rubber Tires Wide Wheel Set – 19.3mm Wide DIY Toy Car & RC Wheel

Product Description

The 2 × 38mm Small Rubber Tires Wide Wheel Set is a compact and durable wheel solution designed for DIY toy cars, RC crawlers, buggies, monster trucks, STEM projects, and small robotic platforms. With an extra-wide 19.3mm tire profile, these wheels provide increased ground contact for improved stability and traction.

Each wheel combines a high-quality rubber tire with a sturdy plastic hub, offering a good balance between grip, durability, and lightweight construction. The wide profile is particularly useful for small vehicles where improved stability is required, helping reduce tipping during turns and uneven movement.

The wheels feature a precision 1.95mm axle hole, designed for a secure friction fit on compatible 2mm steel axles. This allows easy installation without necessarily requiring adhesives or additional set screws.

Their compact 38mm outer diameter makes them suitable for small-scale vehicles and robotic platforms where lightweight and space-efficient wheels are required.

Design and Construction

The wheels feature a wide rubber tire mounted on a plastic hub. The wide tire profile increases the contact area with the ground, helping provide better traction and stability compared with narrower wheels of a similar diameter.

The plastic hub keeps the wheel lightweight while providing a rigid mounting structure for the axle.

The compact design makes these wheels suitable for small robotic chassis, toy vehicles, RC models, and custom mobile platforms.

Working Principle

The wheel transfers rotational movement from the connected motor or axle to the ground. When used with compatible 2mm axles and suitable motors, the rubber tire provides traction for forward, reverse, and turning movements.

The 1.95mm bore is designed to provide a tight friction fit on compatible 2mm axles, helping reduce unwanted wheel movement during operation.

Typical Application Scenarios

Product Disclaimer

Product images are shown for illustrative and representational purposes only. The actual wheels may vary slightly in colour, tread design, dimensions, hub appearance, or other visual details depending on the manufacturing batch.

Motors, axles, chassis, couplings, batteries, controllers, and other accessories are not included unless specifically mentioned in the package contents.

Actual wheel performance depends on the motor, axle, vehicle weight, surface type, traction requirements, and operating conditions.

Important Notes

Axle Compatibility

The wheels have a 1.95mm axle hole and are designed for compatible 2mm axles. Check the actual motor shaft or axle diameter before installation.

Friction-Fit Installation

The precision bore is designed to provide a tight fit on suitable 2mm axles. Actual fit may vary slightly depending on axle tolerance and wheel batch.

Traction

The wide rubber tire provides improved contact and grip, but actual traction depends on the surface, vehicle weight, motor torque, and environmental conditions.

Wheel Alignment

Make sure both wheels are properly aligned with the axles to reduce wobbling and uneven tire wear.
