Uiuaquas 11x4.00-5 Flat-Free Wheel & Tire Assembly, 2-Pack Solid Polyurethane Foam, 6" Rim, Adjustable Hub

This two-pack of 11x4.00-5 solid polyurethane foam tires comes preassembled on a 6" rim with interchangeable hub lengths and included spacers and bearings for a quick swap. Built to remove the worry of flats and routine inflation, these wheels give predictable traction and a stable ride for residential and commercial outdoor equipment.

How does this wheel prevent downtime from flats?

The tire uses a solid polyurethane foam core that cannot lose air, so punctures and slow leaks are eliminated. That means no inner tubes, no pumps, and less maintenance between seasons.

• Solid foam construction removes need for inflation or repair
• Seamless tread reduces risk of cuts and snags
• Rated up to 300 lb per wheel for typical lawn and light utility tasks

Will these wheels fit my mower, cart, or compressor?

Uiuaquas wheels are designed for broad compatibility with common outdoor equipment that uses 11x4.00-5 size tires. The hub accepts either 3/4" or 5/8" bushings and the assembly ships with multiple bearings and spacers to match many factory configurations.

• Rim diameter: 6" with 11" tire diameter and 4" width
• Includes 5/8" bearings, metal spacers and gaskets for hub length adjustment
• Check your current hub/bushing size and model to confirm fit before purchasing

How simple is installation and what hardware is included?

Most replacements can be completed in about half an hour using basic tools. The assemblies arrive preassembled with common bearing sizes and spacers so you can adjust hub length without sourcing extra parts.

• Pre-assembled axle hole compatible with 3/4" axles
• Included: 5/8" bearings, 1/4" and 2/5" metal spacers, and aperture gaskets
• Hub length adjustable between approximately 3.4" and 5" to match your equipment

What performance can I expect on uneven or wet ground?

The dense polyurethane tread gives dependable traction and resists deformation on rough surfaces. While not intended for highway speeds or heavy static loads, these wheels maintain grip and stability for mowing, hauling, and light commercial use.

• Textured, smooth-profile tread balances traction with turf protection
• Stable sidewalls reduce wobble on uneven terrain
• Explosion-proof solid design prevents sudden deflation under typical use

Who is this for: The Uiuaquas 11x4.00-5 flat free wheel and tire assembly is ideal for homeowners, landscapers, and small-business operators who want a low-maintenance replacement for pneumatic 11x4.00-5 tires on zero-turn mowers, garden carts, wheelbarrows, air compressors and similar equipment. Choose these wheels if you need reliable, puncture-proof performance and included bearing/spacer options for a fast retrofit. Note: not suitable for highway driving or extreme static load-bearing—confirm your current hub and bushing sizes before ordering to ensure compatibility.
