GICOOL 11x4.00-5 Flat-Free Lawn Mower Tire & Wheel Kit, 2-Pack — Polyurethane, Centered Hub with Saver Ramps

GICOOL's 11x4.00-5 flat free tire and wheel kit replaces puncturable pneumatic tires with a maintenance-free polyurethane wheel assembly that includes saver ramps and multiple bore adapters for easy fitment.

This 2-piece set is built for homeowners and pros who need reliable, puncture-proof wheels for zero-turn and lawn mower applications. The solid polyurethane construction eliminates inner tubes and air maintenance, while the included saver ramps help protect tires from flat-spotting during long parking periods on hard surfaces or in heat. A pre-assembled centered hub plus a selection of bushings and spacers make it straightforward to adapt to different axle diameters and hub lengths.

Will these wheels fit my mower model?

They are designed for machines that use 11x4.00-5 tires and accept centered hubs in the 3.4"–5" range. The kit ships with a 3.4" centered hub pre-installed and a 3/4" bore bushing; additional fittings allow conversion to 5/8" and 1/2" bores.

• Confirm tire sidewall reads 11x4.00-5 before buying
• Pre-assembled centered hub sizes included: 3.4", 4", 4.5", 5" compatibility via adapters
• Bearing/axle bore options: 1/2", 5/8", 3/4" with supplied bushings
• Replacement fit examples: models like F935, RTZ42, ZTX42 if specs match

How durable are these flat-free polyurethane tires?

The tires are molded from high-strength polyurethane foam that resists wear, tearing, and punctures typical of rubber pneumatic tires. Because there is no air chamber, cuts and nails won’t cause a sudden flat, making them better for rough lawn environments.

• Solid PU construction — no inner tube to puncture
• High wear and tear resistance for long life on turf and hard surfaces
• Rated dynamic load capacity around 330 lbs per wheel
• Smooth tread profile for reduced turf marking and predictable roll

What is the saver ramp and why is it included?

Saver ramps are thin inserts that sit between the wheel and hub to better distribute load and prevent flat-spotting when a mower is parked for long periods. They are especially helpful in hot weather or on hard surfaces where soft polyurethane can develop permanent deformation under sustained pressure.

• Prevents flat spots during extended parking
• Reduces stress on the PU material at wheel-hub contact points
• Easy to install and included with the wheel assembly
• Helps the tire retain round profile for smoother operation

How easy is installation and what extra parts come with the kit?

The wheel arrives pre-assembled with a 3.4" centered hub and a 3/4" bore bushing to speed installation. The package also includes multiple bushings, nylon and steel spacers, and fittings so you can adjust the hub bore and track width without buying separate adapters.

• Included: four 5/8" bore fittings for axle sizing flexibility
• Ten 1/4" and eight 1/2" width nylon wheel spacers for alignment
• Eight steel spacers for secure fit and bearing support
• Comes as a 2-piece set — both left and right replacement wheels

Who is this for? The GICOOL 11x4.00-5 flat free tire and wheel kit is best for homeowners, landscapers, and fleet users who want a low-maintenance, puncture-resistant solution for zero-turn mowers and compact garden tractors. If you value predictable rolling performance, reduced downtime from flats, and the ability to adapt to varied axle sizes, this kit offers a practical, ready-to-install alternative to conventional pneumatic tires.
