Cubesprings 11x4.00-5 Flat-Free Lawn Mower Tires 2-Pack — Gray Alloy Rims, Solid Polyurethane, Includes Bearing/Spacer Kit

Cubesprings 11x4.00-5 flat-free lawn mower tires are solid polyurethane replacement tires preassembled on gray alloy rims, sold as a 2-pack and built to eliminate punctures and reduce maintenance.

These 11x4.00-5 tires are designed for zero-turn mowers, garden tractors, and other small utility machines where dependable, puncture-free performance matters. Each unit pairs a solid polyurethane tire with a robust alloy rim and includes a multi-bore bearing and spacer kit so you can adapt the wheel to common hub sizes without hunting for parts.

Will these tires fit my mower or tractor?

Compatibility depends on your existing tire and hub dimensions rather than the vehicle model alone. Check the sidewall of your current tire for size markings and measure the hub bore and bearing diameter to confirm a match.

• Nominal tire diameter: 11 inches
• Tire width: 4 inches; rim diameter: 7 inches
• Preinstalled bearing bore: 3/4 inch; additional 5/8 and 1/2 inch bearings included
• Includes various steel and nylon spacers for common hub fits

How durable are these solid (flat-free) tires?

The tires use high-density polyurethane foam engineered for abrasion and tear resistance, so they avoid the flats and slow leaks that plague pneumatic tires. The solid construction also resists dry rot and weathering, reducing replacement frequency for routine lawn use.

• Material: premium polyurethane foam for wear resistance
• Designed to withstand yard debris and rough surfaces
• Alloy steel rims reduce rim damage under heavy loads
• Dynamic load rating around 330–350 lbs per wheel

What hardware comes with the wheels to ensure a proper fit?

Each wheel arrives preassembled with a 3/4" bore bearing and a kit of additional bearings and spacers so you can size the assembly to your hub. The assortment covers 5/8" and 1/2" bores and includes steel and nylon spacers of varying lengths to achieve correct axle clearance and bearing preload.

• Two 5/8" bore bearings and two 1/2" bore bearings included
• Four 0.44" long steel spacers; two 0.2" steel spacers
• Six 0.44" long nylon spacers; two 0.22" long nylon spacers
• Preassembled 3/4" bearing for users with that hub size

How much weight can each wheel safely carry?

These Cubesprings wheels are rated for heavy hobby and light commercial duty; each wheel supports up to about 330–350 pounds dynamically. That capacity makes them suitable for small utility trailers, zero-turn mowers, and garden tractors when used within the machine’s overall load limits.

• Dynamic load capacity roughly 330–350 lbs per wheel
• Solid construction spreads loads across the rim and hub
• Not intended for highway or high-speed use
• Check vehicle weight distribution before use

Who this is for: These 11x4.00-5 Cubesprings flat-free tires are for homeowners, landscapers, and small-farm operators who want maintenance-free wheels that resist punctures, weathering, and common yard hazards. Choose these tires if you need a reliable replacement for front wheels on zero-turn mowers or other small equipment, if you prefer solid tires over inner-tube repairs, or if you want a ready-to-fit wheelset with a comprehensive adapter kit to save time during installation.
