BOOTOP PIN 11x4.00-5 Lawn Mower Flat-Free Tires 2-Pack with Rims & Universal Adapter, 330 lb Capacity

BOOTOP PIN 11x4.00-5 flat-free lawn mower tires are solid polyurethane replacement tires with included rims and adapter kit, designed to eliminate flats and fit a wide range of garden equipment.

These 11x4.00-5 tires come as a two-pack with mounted rims and a universal spacer/bushing kit so you can replace pneumatic wheels without inflating, patching, or checking pressure. Built from high-density polyurethane foam, they offer puncture-proof performance and cushioning for turf while supporting up to 330 lbs per tire. The centered hub can be adjusted from 3.4" to 5" using the included spacers and accepts 3/4", 5/8", or 1/2" precision bearings for broad compatibility with mowers, carts, and equipment.

Will these tires fit my zero-turn mower or garden cart?

Yes—these tires are made for universal compatibility across many outdoor power machines. The rim is built around a centered hub that can be adapted to several hub widths using the supplied spacers and bushings.

• Nominal tire size: 11" diameter x 4" width (11x4.00-5)
• Adjustable hub center: 3.4" to 5" using included spacers
• Accepts bearings: 3/4", 5/8", or 1/2" (precision bushings provided)
• Common uses: zero-turn mowers, garden carts, wheelbarrows, generators

How do flat-free polyurethane tires compare to pneumatic tires?

Polyurethane solid tires remove the hassle of inflation and the risk of punctures while delivering stable, long-lasting service. They sacrifice some ride softness of air-filled tires but reduce downtime from flats and maintenance.

• Flat-free: no air, no leaks, no puncture repairs
• Durable: high-strength polyurethane resists tearing and weathering
• Turf protection: smooth tread and elasticity cushion wheels to reduce scuffing
• Load rating: up to 330 lbs per tire for heavy-duty tasks

What is included with the 2-pack and how hard is installation?

The set includes two 11x4.00-5 solid tires pre-mounted on rims plus a universal adapter kit with spacers and bushings. Installation is straightforward for anyone comfortable removing a wheel: swap the old wheel, fit the adapter spacers to match hub width, and install compatible bearings.

• Two solid tires already mounted on rims
• Adapter kit: spacers to set hub center between 3.4" and 5"
• Interchangeable bushings for 3/4", 5/8", and 1/2" bearings
• No inflation tools needed and minimal ongoing maintenance

Where should I not use these tires and what limitations exist?

These solid polyurethane tires are ideal for off-road, lawn, and equipment use, but they are not intended for highway speeds or for supporting continually static loads where compression set could occur. Always verify machine axle and bearing sizes before installation.

• Not rated for highway or high-speed road use
• Not designed for permanent static load-bearing applications
• Double-check axle diameter and hub width before fitting
• May feel firmer than pneumatic tires over very rough terrain

Who is this for: The BOOTOP PIN 11x4.00-5 flat-free tire set is aimed at homeowners, landscapers, and equipment owners who want a low-maintenance replacement for common 11x4-5 pneumatic wheels. It's especially useful if you need reliable, puncture-proof wheels for zero-turn mowers, utility carts, wheelbarrows, pressure washers, or portable generators and prefer a quick swap with an adapter kit rather than ongoing tire maintenance.
