4.5" Big Wheels (2) (DUB450RV)

Two 4.5-inch inflatable wheels come in a two-pack, designed for RC vehicles and other hobby builds that use a 4 mm (5/32 inch) axle. The tires are smooth and inflatable, with a tiny valve on the tire side for quick inflation or deflation. They feature two-piece bolt-together hubs and hub caps for secure mounting and straightforward setup.

These wheels are suited for 4 mm axles and offer a larger footprint to improve traction. The inflation valve lets you tailor grip and ride feel by adjusting air pressure, while the two-piece hub design simplifies installation and maintenance. With two wheels per package, you’re ready to upgrade or replace a pair on compatible builds.
