GICOOL 4.00-6 Replacement Tire and Inner Tube Set, 2 Pack, 13" Heavy Duty Tire and Wheel, TR-13 Straight Valve Stem, for wheelbarrow Trolley Dolly Garden Wagon Wheel Replacement

What It Is

A two-pack of 4.00-6 pneumatic tires mounted on 13-inch rims with TR-13 straight valve stems, designed for wheelbarrows, garden wagons, trolleys, and dollies that need a heavy-duty replacement for flat or worn-out wheels.

Fitment & Compatibility

Before buying, confirm three things:

• Tire size: Your current tire must be marked 4.00-6 (4-inch width, 6-inch rim diameter). This set has an overall diameter of about 13 inches, so measure your old tire’s height to be sure it matches.
• Axle hole: The wheel hub usually fits a 5/8" or 3/4" axle. Measure your axle diameter—these wheels come with standard bushings or bearings, but you may need to swap them if your axle is non-standard.
• Valve type: The TR-13 straight stem works with most standard tire pumps. If your wheelbarrow has a tight clearance around the hub, check that the stem won’t hit the frame.

This set is aftermarket, not OEM-specific. It fits most brands (e.g., True Temper, Jackson, Ames) as long as the size matches. No deck or mower fitment—these are strictly for push-type utility vehicles.

Key Things to Know

• Quality vs. price: At $25 for two tires and tubes, these are budget-friendly but not commercial-grade. Sidewalls are thinner than premium brands—fine for occasional garden use, not daily construction hauling.
• Installation: Tires come pre-mounted on rims, but tubes are separate. You’ll need to install the tube inside the tire, which takes about 10 minutes per wheel. Inflate to 30-40 PSI max—overinflating can burst the tube.
• Common gotcha: The included inner tube may have a slow leak if the rim has sharp burrs. Sand the rim edge before installing the tube to prevent punctures.
• Load capacity: Each tire supports roughly 300-400 lbs. Don’t exceed that per wheel, or you risk sidewall failure.

Should You Buy It

Buy this set if you need a quick, affordable replacement for a flat 4.00-6 tire on a garden wagon or light-duty wheelbarrow. Skip it if you’re hauling heavy loads daily—invest in a thicker sidewall tire like a Marathon or Kenda for that use.
