AR-PRO 2-Pack 9x3.50-4 Flat-Free PU Tire on Wheel Assemblies with Adapters and 3/4-in Bushings

Upgrade your lawn and garden toolkit with AR-PRO’s 2-pack of flat-free PU tire on wheel assemblies. Sized 9x3.50-4 inches, these assemblies are designed to fit a range of walk-behind mowers and similar wheeled equipment. The kit includes a universal adapter system that accommodates a 3/4-in bushing with a centered hub of about 3.5 inches, helping you swap wheels without extra parts.

Why choose flat-free PU tires

• Flat-free polyurethane (PU) tires deliver reliable performance across grass, gravel, and hard surfaces, reducing downtime from punctures.
• PU tires are lighter and smoother than solid rubber counterparts, with durable grip and weather resistance.

What's included and compatibility

• Two PU tire-on-wheel assemblies with grease fittings for easy lubrication.
• Universal adapter kit containing four nylon spacers and eight steel washers for broad mounting compatibility.

Durability and materials

Each assembly features a yellow steel wheel paired with a PU tire. With a rated load up to 300 pounds, these wheels are built to handle varied terrain while remaining non-marking and weather-resistant. PU combines grip with resilience and UV resistance, offering a longer service life on exposed outdoor equipment.

Ideal uses and placement

• Walk-behind mowers, garden carts, wheelbarrows, and hand trucks are common applications.
• Air compressors, generators, and other wheeled tools may also benefit from a stable, puncture-resistant ride.

Installation tips and fit notes

Before ordering, verify your current tire sidewall matches the 9x3.50-4” size and confirm the hub length is centered at 3.5 inches. The universal adapter kit helps with mounting on a wide range of equipment, and grease fittings support routine maintenance to keep the wheels turning smoothly.
