(1-Set) RRQ 4.80/4.00-8" Tire and Inner Tube Set, Universal Replacement Pneumatic Tires, Fits 15.5-inch wheels, TR-13 Straight Valve Stem, for Wheelbarrows, Dollies, Trolleys, Garden Carts and More

What It Is

This is a set of two 4.80/4.00-8 pneumatic tires with matching inner tubes, designed for wheelbarrows, garden carts, dollies, and trolleys. They replace worn or flat tires on light-to-medium-duty equipment that uses 8-inch rims.

Fitment & Compatibility

Before buying, verify these three measurements on your current tire:

• Tire size: Must be 4.80/4.00-8 (4.80-inch width, 4.00-inch profile, 8-inch rim diameter). This is not a 15.5-inch wheel – the tire fits a 15.5-inch overall diameter wheel/rim assembly.
• Rim width: Accepts rims 3.0–4.0 inches wide (measure the metal rim, not the tire).
• Valve stem: TR-13 straight valve stem (common on wheelbarrows). If your equipment uses a bent or short valve, this won’t fit without modification.

No specific brand or model compatibility – this is universal for any 8-inch rim within that width range. Not for lawn tractors, zero-turns, or mower decks.

Key Things to Know

• Installation: Moderate difficulty. You’ll need tire irons and a pump. Inner tubes are pre-installed inside the tire, but you must seat the bead evenly to avoid pinching the tube.
• Load rating: Rated for light-to-medium loads (typically up to 300 lbs per tire). Not for heavy-duty wheelbarrows or powered equipment.
• Common gotcha: The TR-13 valve stem is straight and short. If your wheel has a deep hub or requires a bent stem for clearance, you’ll need a valve extender or a different tube.
• Quality: Budget-tier rubber. Tread is basic, sidewalls are thin. Expect shorter lifespan than premium brands, especially under UV exposure or heavy loads.

Should You Buy It

Buy this set if you need a cheap, quick replacement for a flat tire on a hand-pushed wheelbarrow, garden cart, or dolly with an 8-inch rim. Skip it if you need heavy-duty durability, have a powered machine, or require a specific valve stem angle – spend more on a branded tire instead.
