Cubesprings 13x5.00-6 Flat-Free Lawn Mower Tire & Wheel — Gray, Solid Polyurethane, 500 lb Load

Cubesprings 13x5.00-6 flat-free tire and wheel is a puncture-proof replacement wheel assembly for lawn mowers and small garden tractors, built with solid polyurethane and a heavy-duty alloy rim for up to 500 lb load capacity.

If you’re replacing front or rear small-diameter mower wheels and want a maintenance-free option, this assembled 13 x 5.00-6 wheel saves you from flats and frequent air checks. It ships preassembled with a steel wheel and solid foam tire and includes a kit of interchangeable bearings and spacers so you can fit it to a wide range of hub sizes. The construction emphasizes wear resistance and durability for routine lawn care and towing small attachments—this is designed for equipment, not highway use.

How do I know this wheel will fit my mower?

Check three things on your existing wheel: overall tire size markings (13x5.00-6), the rim diameter, and the hub/bearing bore measurement. The Cubesprings unit arrives with a 3/4" bore installed and a kit of alternative bearings and spacers to adapt to common hub sizes.

• Confirm sidewall marking: 13 x 5.00-6 for diameter and width match.
• Rim (wheel) diameter: designed to suit 6" rim systems and similar lawn mower hubs.
• Bearing options included: 3/4" installed, plus 5/8" and 1/2" bearings and multiple spacers.

What load and durability can I expect from a flat-free polyurethane tire?

The solid polyurethane compound resists punctures and minimizes wear compared with pneumatic tires, providing a sturdy rolling surface for lawn equipment. The combined wheel assembly is rated to support up to 500 pounds dynamic load, appropriate for front wheels on many zero-turn mowers and small garden tractors when used within normal operating limits.

• Material: premium solid polyurethane foam resists tears and abrasion.
• Rated capacity: up to 500 lbs dynamic load for the assembled wheel.
• Rim: alloy steel construction designed for rugged use and impact resistance.

Which adapters and hardware come with the wheel, and why does that matter?

To avoid shopping for separate bearings, the package includes multiple bore bearings and a selection of steel and nylon spacers so the wheel can be fitted to different axle setups. This universal kit helps match the wheel to your mower’s spindle geometry and keeps the wheel centered for smooth rotation.

• Bearing kit: four 5/8" and four 1/2" replacement bearings in addition to the 3/4" installed bore.
• Spacers: a mix of steel and nylon spacers in several lengths to fine-tune hub alignment.
• Pre-assembled: wheel arrives ready to mount, reducing install time.

Will this wheel change mower handling or maintenance needs?

Because it’s solid and puncture-free, you’ll eliminate flats and routine air-pressure checks, simplifying upkeep. The slightly firmer ride of a solid polyurethane tire compared with an inflated tire may change ride feel slightly, but it improves reliability and reduces downtime from punctures.

• No air pressure: no flats, no inner tubes, and no seasonal airing.
• Reduced downtime: fewer roadside repairs and replacements in typical yard conditions.
• Care: periodic inspection for wear and hub tightness is still recommended.

Who is this for? The Cubesprings 13x5.00-6 flat-free tire and wheel is aimed at homeowners, landscapers, and small-property caretakers who run zero-turn mowers, lawn tractors, or utility carts and want a low-maintenance, durable wheel replacement. It’s a practical upgrade if you experience frequent punctures or need a wheel that adapts to different hub sizes without buying extra parts. Note: not intended for highway speeds or road towing—verify your mower’s hub and wheel size before ordering to ensure compatibility.
