Flat-Free Wheel with Ball Bearing, 12" Dia x 3"W, Semi-Pneumatic, Steel Wheel with Rubber Tread, 1 Each

The semi-pneumatic wheel features a 3-inch center-mount hub and a puncture-resistant rubber tread. It contains a pocket of non-pressurized air, which provides cushioning without the need for inflation. The symmetrical center-mount hubs ensure equal clearance on both sides of the wheel. Additionally, the lug-fit rims are designed with a series of indentations that align with the tire’s lugs, securely locking the tire in place to prevent slipping on the rim.
