DOUBLE BRIDGE 2-Pack 14.5" 3.50-8 Wheelbarrow Pneumatic Wheels — 5/8" Bore, Adjustable 3–7" Hub, Ribbed Tread

These replacement wheel assemblies are built for yard equipment that needs a durable, air-filled tire with flexible hub spacing. Each kit includes two ribbed-tread 3.50-8 tires (14.5" diameter, 3.5" width) fitted with 5/8" bushings and a selection of nylon spacers and zinc washers so you can adapt the hub length to your cart, wheelbarrow, or garden trailer.

How do these wheels fit different axle and hub sizes?

The wheels arrive with a standard 5/8" axle bore and an adapter assortment that lets you extend hub length from about 3" up to 7". Use the included 1/2" and 1" nylon spacers plus zinc washers to dial in the correct spacing for your frame so the wheel spins freely without wobble.

• Factory bore: 5/8" for common garden axles
• Included spacers: four 1/2" and two 1" nylon pieces
• Two 0.08" zinc washers for secure positioning
• Adjustable effective hub length: approximately 3"–7"

What load and terrain are these tires designed for?

The pneumatic construction and ribbed tread balance cushioning with traction for soft lawn, dirt, and paved surfaces. Each wheel supports light-to-medium loads typical of wheelbarrows, garden wagons, and spreaders—suitable for hauling soil, mulch, tools, and similar cargo around the yard.

• Rated load capacity: up to 300 lb per wheel (non-highway use)
• Ribbed tread for grip on grass, soil, and driveway surfaces
• Pneumatic sidewalls absorb shocks and reduce jarring during use
• 3.5" tire width for stability on narrow frames

How do I install and maintain these wheels?

Installation is straightforward: remove the old wheel, slide the wheel onto the axle, then add spacers and washers until the wheel runs true. Keep the tire inflated to recommended pressure and inspect bushings and spacers periodically to prevent loosening or axial play.

• Tools needed: wrench or pliers to remove cotter pin/bolt
• Check and set tire pressure before first use
• Tighten axle fasteners after a short trial run
• Inspect spacers and bushings for wear annually

Who is this for? These DOUBLE BRIDGE 3.50-8 replacement wheels suit homeowners, landscapers, and small-scale contractors who need reliable, cushioned wheels for wheelbarrows, garden carts, and light equipment. If your current wheel has a 14.5" diameter, 3.5" width, and 5/8" bore—or you need a wheel that adapts to varying hub lengths—this two-pack simplifies swapping worn or damaged wheels and restores stable, quieter operation across a range of yard tasks.
