4.10/3.50-4 Inner Tube with TR-87 Bent Valve Stem Rubber Tire Tube Replacement for Wheelbarrows, Mowers, Hand Trucks ATVs, Fits 10" 4.10/3.50х4 Pneumatic Tires

What It Is

This is a replacement inner tube designed for 10-inch pneumatic tires with a 4.10/3.50-4 size rating. It’s meant for wheelbarrows, lawn mowers, hand trucks, ATVs, and other small utility equipment that uses tubed tires.

Fitment & Compatibility

Before buying, confirm your tire sidewall says 4.10/3.50-4 or 3.50-4 (these are interchangeable). The tube fits any 10" wheel with that tire size, regardless of brand. Check that your rim has a standard valve hole (the TR-87 bent stem works for most mower and wheelbarrow rims). If your original tube had a straight stem or a different stem angle, this bent stem may require you to slightly enlarge the rim hole or use a different installation technique. No specific mower deck or model compatibility—this is a universal tire part.

Key Things to Know

• Quality: This is a budget inner tube. It’s functional but may be thinner rubber than OEM or premium brands. Expect shorter lifespan if used on rough terrain or heavy loads.
• Installation difficulty: Easy for anyone who’s changed a bike tire. You’ll need tire irons and a pump. Watch for pinching the tube between the tire bead and rim—dust the tube with talc powder to reduce friction.
• Common gotcha: The TR-87 bent valve stem is short and angled. It may not clear some deep-dish rims or wheel covers. Test fit before mounting fully.
• Replacement frequency: If you get a puncture, just patch this tube like a bike tube—no need to replace immediately unless the rubber is dry-rotted.

Should You Buy It

Buy this if you need a cheap, quick replacement for a flat tube on a wheelbarrow, mower, or hand truck and you’re comfortable with basic tire work. Skip it if you need heavy-duty performance for commercial use, ATV off-roading, or high-pressure applications—spend more on a thicker tube with a straight stem for those.
