Soiiw 13-inch 4.00-6 Flat Free Wheel Set – 2-Pack, 300 lb Capacity, Universal Fit

Upgrade Your Carts with Soiiw 13-inch Flat Free Wheel Set

The Soiiw 13-inch 4.00-6 replacement wheel set is designed to endure tough tasks, from yard work to daily hauling. The solid PU foam tire provides a dependable roll without the need for an inner tube, delivering a clean, maintenance-free experience. This inflate-free design reduces downtime and keeps your workflow steady, even when you’re moving heavy loads across uneven surfaces.

With a dynamic load capacity of 300 lbs, these wheels balance strength and control. The double sealed ball bearings help maintain smooth rotation, contributing to a steadier ride as you push or pull carts on concrete, gravel, or grass. The hub length is offset at 2.2 inches, a feature that helps maintain alignment during operation, while the rim diameter measures 8.6 inches for a stable presence in the transport path.

Key compatibility and setup details matter here. The wheel set is designed to accommodate common 4.00-6 configurations and offers a versatile bore option of 5/8 inch or 3/4 inch. Eight spacers and four pins are included to support proper spacing and secure installation, along with four replacement bearings to help your wheels stay balanced over time.

What this upgrade can mean for your workflow includes fewer interruptions from punctures, less maintenance compared with traditional pneumatic tires, and the flexibility to swap wheels across a range of hand trucks, garden carts, and poly dump carts. While the design emphasizes broad compatibility, it is wise to verify bore size, hub length, and axle compatibility before purchase to ensure a smooth fit with your equipment.

Usage scenarios span everyday tasks to more demanding applications. Expect a steady roll while transporting soil, mulch, or tools; benefit from reliable performance when moving equipment around workshops or yards; and enjoy a straightforward upgrade path for aging wheels that helps restore stability and ease of use without complex modifications.

• Reliable, puncture-free operation with a solid PU tire design.
