Product titles and fields [S1]. All casters use a 4 x 4-1/2 in plate.

Which tread for which ground

Grass, soil and gravel: the 10 x 3 in semi-pneumatic casters. The large, soft wheel rolls over ruts and does not go flat.
Paved paths and driveways: 6 x 2 in polyurethane rolls easiest and carries the most.
Mixed ground: 6 x 2 in mold-on rubber is quieter and grips better than polyurethane.
Smooth concrete only: 4 x 2 in phenolic. Small, hard wheels sink in soft ground.

Replacing a wheel or caster

If the cart has plate casters, match the 4 x 4-1/2 in plate and the bolt pattern. If only the wheel is worn, match the diameter, tread width, bore and hub length. There are no pneumatic tires or wheels larger than 10 in on this page.

Air and foam tires: hand truck wheels. Carts: carts and platform trucks.
