4.80/4.00-8" Tire and Inner Tube Set, 550 lbs Capacity, Universal Fits 15.5" Wheel, Universal Replacement for Wheelbarrows, Hand Trucks, Lawn Mowers, Dollies, Trolley and Garden Carts

What It Is

This 4.80/4.00-8" tire and inner tube set is a universal replacement for any wheeled equipment that uses a 15.5" outer diameter tire on an 8" rim—common on wheelbarrows, hand trucks, lawn mowers, dollies, trolleys, and garden carts. It supports up to 550 lbs per tire, making it suitable for heavy-duty hauling and rough terrain.

Fitment & Compatibility

Before buying, check three things:

• Rim size: This tire fits only an 8" rim (measured bead-to-bead). It will not work on 6" or 10" rims.
• Tire dimensions: The 4.80/4.00-8 designation means the tire is about 4.8" wide and 15.5" tall when inflated. Measure your current tire’s outer diameter and width to confirm it matches.
• Axle or hub: Ensure your wheel hub or axle fits the tire’s center hole (typically 5/8" or 3/4" bore, but measure yours). This is a universal tire, not a direct OEM replacement—so no brand-specific fitment guarantees. It works on most walk-behind mowers, but check that the tire’s tread depth and width don’t rub against the mower deck or frame.

Key Things to Know

• Quality: At this price, expect basic rubber with moderate tread life. The 550 lbs capacity is per tire, so a two-wheel cart can handle 1,100 lbs total.
• Installation: Mounting the tube and seating the bead on an 8" rim is straightforward with tire irons. A small amount of dish soap on the rim helps. No special tools required.
• Gotcha: The included inner tube may have a standard Schrader valve (car-style). Make sure your pump or air source fits. Also, the tire is pre-lubed from the factory—check for excess grease before mounting to avoid slipping.
• Weight: Each tire weighs about 6-7 lbs, so shipping cost may add up if buying multiple.

Should You Buy It

If you need a no-frills, heavy-duty replacement for a worn tire on a wheelbarrow, cart, or mower with an 8" rim, this set is a budget-friendly pick. It’s not for premium mowers or frequent commercial use, but for DIY repairs and light-to-medium duty, it gets the job done.
