AR-PRO 9x3.50-4 Lawn Mower Tire & Wheel Assemblies, 2-Pack — Yellow Steel, Flat-Free PU, 3.5" Center Hub, Grease Fittings

These are two 9x3.50-4" flat-free polyurethane tire and wheel assemblies with centered 3.5" hubs and a universal adapter kit for quick replacement on lawnmowers and light equipment.

If you're replacing worn tires on a walk-behind mower, garden cart, generator, or small trailer and want a puncture-resistant option, this AR-PRO 2-pack delivers durable PU tires mounted on yellow-steel wheels with grease fittings and adapters. Designed to match common 9.29" overall diameter and 3.50" tire width measurements, these assemblies reduce downtime from flats and give a reliable, low-maintenance rolling solution.

Will these wheels fit my mower or garden cart?

Measure your current tire's sidewall markings to confirm compatibility: the AR-PRO assemblies suit 9x3.50-4 size tires and require a 3/4" bushing bore and a 3.5" centered hub. If your current setup uses the same diameter and bore, these should mount without modification using the included adapter kit.

• Overall tire diameter: ~9.29 inches
• Tire width: 3.50 inches
• Rim diameter: 4 inches
• Bore/bushing size: 3/4 inch; centered hub length: 3.5 inches

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

Polyurethane (PU) tires mimic many properties of rubber—good grip and shock absorption—while eliminating puncture risks and frequent air-pressure checks. They are lighter, more tear- and cut-resistant than standard rubber, and they won’t leave marks on delicate surfaces.

• Flat-free: no air, no flats
• UV and weather resistant for longer life outdoors
• Non-marking and abrasion resistant on most surfaces

What load and performance can I expect from each assembly?

Each AR-PRO unit supports up to 300 pounds, suitable for most lawnmower decks, garden carts, air compressors, and similar equipment. Grease fittings on the hub help maintain smooth rotation and extend bearing life under regular use.

• Maximum load capacity: 300 lbs per wheel
• Includes grease fitting for easier maintenance
• Yellow steel wheel for durability and corrosion resistance

What comes in the 2-pack and how easy is installation?

The package includes two assembled 9x3.50-4 PU tires mounted on wheels plus a universal adapter kit to fit many axle setups. The adapter kit contains nylon spacers and steel washers so you can adjust for tight, wobble-free mounting on a variety of equipment.

• 2 x PU tire-and-wheel assemblies with centered hubs
• Universal adapter kit: 4 nylon spacers and 8 steel washers
• Preinstalled grease fittings for immediate maintenance

Who is this for: These AR-PRO flat-free tire-and-wheel assemblies are ideal for homeowners and small-business users who want dependable, low-maintenance wheels for lawnmowers, wheelbarrows, garden carts, small trailers, generators, and other light wheeled equipment. Choose this kit if you need a puncture-proof upgrade with a straightforward fit—just verify your current tire sidewall sizes and bore dimensions before ordering.
