DU-BRO 3-1/2" Treaded Wheel Set for RC Airplanes – Low Bounce Captive Air (2-Pack)
This 2-pack of DU-BRO 3-1/2" diameter treaded wheels delivers a consistent wall thickness that keeps the tire balanced, making them a solid choice for radio-controlled airplanes operating from grass or paved runways. Each wheel comes with a sporty nylon metallic hub that adds a touch of style while maintaining durability. Designed as low-bounce captive air tires, they have become a widely used option among RC pilots over the decades. The plastic construction keeps the weight manageable at 0.1 kg per wheel, minimizing added drag during flight and takeoff.
What makes these wheels suitable for both grass and paved runways?
The treaded surface provides grip on softer grass surfaces while still rolling smoothly on paved strips. The low-bounce captive air design helps absorb minor impacts without excessive rebound, reducing the chance of the plane bouncing on landing or rolling unevenly. Combined with the consistent wall thickness, these wheels offer predictable handling whether you're flying off a manicured grass field or an asphalt runway.

Build quality and balance
The wall thickness is even around the entire tire, which helps keep the wheel balanced during high-speed rotation. This reduces vibration transmitted to the landing gear and airframe. The nylon hub is molded to fit securely without wobble, and its metallic appearance complements a wide range of model designs.
Common questions about this wheel set
- Are these wheels pre-assembled with axles? The supplied data does not specify whether axles are included. The wheels come as a pair with hubs, so you will typically need to mount them on your own landing gear axle.
- Can these be used on other types of RC vehicles? They are designed for airplanes. The tread pattern and low-bounce characteristics are optimized for model aircraft, but some hobbyists may adapt them for other uses—though that is not their intended purpose.
- What is the hub diameter or axle size? The supplied data does not include the inner hub diameter or axle size. It is recommended to measure your existing axle or refer to manufacturer documentation for compatibility.
- Are these wheels intended for both electric and glow/gas powered planes? The data does not specify power type restrictions. The wheels themselves are lightweight plastic, and their performance should be consistent regardless of the plane's power source as long as the weight and landing gear are suitable.
