Cubesprings 13x6.50-6 Flat-Free Lawn Mower Tires — Preassembled Polyurethane Front Casters, 500 lb Load Capacity

Cubesprings 13x6.50-6 flat-free lawn mower tires are solid polyurethane front tires engineered to replace 13x6.50-6 tires on zero-turn mowers and garden tractors, delivering puncture-proof performance and a load capacity up to 500 lbs.

These Cubesprings replacement tires are a pre-assembled, no-air option designed for front caster wheels on zero-turn mowers and similar equipment. Built from dense polyurethane foam over a heavy-duty alloy-steel wheel, they remove the need to worry about flats and frequent pressure checks. The package includes multiple bearings and spacers to adapt the hub bore to common mower specifications so you can fit them without hunting down extra parts.

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

They are sized for applications that use 13" outer diameter, 6.5" width, and a 6" rim diameter. The tires come pre-assembled with a 3/4" bore and include additional bearings and spacers to adapt to most front hub setups.

• Check your current tire sidewall for 13x6.50-6 sizing.
• Measure hub/bearing bore: kit includes 3/4", four 5/8", and four 1/2" bearings.
• Center hub length adjusts between approximately 5.6" and 8.7".

How durable and maintenance-free are these solid tires?

Made from high-strength polyurethane, the tires resist wear, tearing, and punctures far better than air-filled rubber tires. Because they are solid, there’s no risk of flats and no need for inflation or seasonal pressure checks.

• Polyurethane foam construction for abrasion and tear resistance.
• Corrosion-resistant alloy-steel wheel for long service life.
• No inner tube, no air pressure maintenance required.

What load and usage limits should I expect?

Each Cubesprings 13x6.50-6 tire is engineered to support up to 500 lbs dynamic load capacity, making them suitable for heavy mowing and towing loads typical of residential and light commercial use. They are intended for off-highway use only.

• Rated dynamic load: up to 500 lbs per tire.
• Designed for lawn and garden equipment; not for highway or public road use.

What hardware is included and how do I adapt it?

The tire ships with a comprehensive adapter kit so it fits a variety of front hub setups without additional purchases. Bearings, steel and nylon spacers are provided to match common bore sizes and align the wheel on the mower spindle.

• Included bearings: pre-assembled 3/4" plus four 5/8" and four 1/2" spare bearings.
• Spacers: eight 0.44" steel, four 0.2" steel, twelve 0.44" nylon, four 0.22" nylon spacers for hub alignment.
