The DU-BRO Big Wheels are the perfect upgrade for RC pilots who want large, soft, and realistic-looking tundra-style tires for their airplanes. These wheels are designed to handle rough fields, grass runways, and uneven terrain while giving your aircraft a true bush-plane appearance. Whether you’re building a scale Cub, a tundra-style bush plane, or simply want smoother landings, Big Wheels deliver impressive performance and durability. These wheels feature smooth inflatable tires equipped with DU-BRO’s reliable positive-seal air valves, allowing you to inflate or deflate the tires to the firmness you prefer. Adjustment is easy—just use the tiny built-in valve located on the side of each tire. Softer air pressure provides extra shock absorption for rough fields, while firmer pressure offers smoother rolling on harder surfaces. Each wheel includes two-piece bolt-together hubs and hub caps, creating a strong, solid wheel that maintains its shape during takeoff, landing, and taxiing. The hubs also make it easy to service or adjust the wheel whenever needed. These wheels are designed for models using a 5/32" (4 mm) axle diameter, making them compatible with many medium- and large-size RC aircraft.

If you want authentic looks, flexible air-pressure adjustments, and excellent rough-field performance, the DU-BRO Big Wheels are the perfect addition to your RC airplane.
