4.10/3.50-5 Heavy Duty Replacement Inner Tube with TR-87 Bent Valve Stem (2-Pack) - for Wheelbarrows, Mowers, Hand Trucks,Garden Carts,Golf Cart, Mowers and More (4.10/3.50-5")

What It Is

This is a heavy-duty replacement inner tube (4.10/3.50-5 size) with a TR-87 bent valve stem, sold as a 2-pack. It’s designed for small pneumatic tires on wheelbarrows, lawn mowers, hand trucks, garden carts, and golf carts that use a 5-inch rim.

Fitment & Compatibility

Before buying, confirm your tire size is marked 4.10/3.50-5 or 3.50-5 (the tube fits both). The rim diameter must be exactly 5 inches – measure the rim’s outer edge, not the tire. The TR-87 bent valve stem suits applications where a straight stem would be hard to access (e.g., deep-dish wheels on mowers or carts). This tube is a universal aftermarket part, not OEM-specific, so it works across brands (Husqvarna, John Deere, Craftsman, etc.) as long as the size matches. Check that your current tube has a bent stem; if it’s straight, this will still fit but the stem angle may change routing.

Key Things to Know

• Quality: Heavy-duty rubber is thicker than standard tubes, reducing puncture risk, but it’s still air-filled – not a foam or solid replacement.
• Installation difficulty: Easy for DIYers – remove wheel, deflate old tube, pry tire off rim, swap tubes, and reseat. A tire spoon or pry bars help; avoid pinching the new tube between rim and tire.
• Common gotchas: Over-inflation can cause blowouts – stick to the tire’s sidewall PSI rating (usually 20-40 PSI). The bent stem may need a slight twist to align with the rim hole; don’t force it or the stem can tear.
• Two-pack value: Cheaper per tube than buying singles, and handy to have a spare for another wheel or future flat.

Should You Buy It

Buy this if you have a flat on a 5-inch wheelbarrow, mower, or cart tire and want a durable, easy-to-install fix. The bent stem is a plus for hard-to-reach rims, and the 2-pack is a solid value for the price. Skip it if you need a straight stem or a tube for a different rim size.
