TICONN 4.10/3.50-4 Tire Inner Tube, 2 Pack Inner Tire Tube for Wheelbarrow Tires, Replacement Tube with TR-87 Bent Valve Stem for Wheelbarrows, Mowers, Hand Trucks, ATVs

What It Is

This is a 2-pack of inner tubes designed to fit inside pneumatic tires with a 4.10/3.50-4 size rating. It’s intended for wheelbarrows, lawn mowers, hand trucks, small ATVs, and similar equipment that uses a 4-inch rim diameter tire.

Fitment & Compatibility

Before buying, check these three things:

• Tire size: The tube fits tires marked 4.10/3.50-4 (width 4.10” or 3.50”, rim diameter 4”). It will also work with 4.00-4, 3.50-4, and 4.10-4 tires. Measure your tire sidewall if unsure.
• Rim diameter: The tube is for 4-inch rims only. Do not use on 5-inch or larger rims.
• Valve stem: This tube has a TR-87 bent valve stem (90-degree angle, 1.5” long). It’s ideal for machines where a straight stem would be hard to reach (e.g., wheelbarrows with hubcaps or mowers with tight clearance). If your application needs a straight stem, this won’t work.

No specific brand or model restrictions—this is a universal aftermarket part for any 4” rim with the correct tire size.

Key Things to Know

• Quality: Tubes are made of butyl rubber, which holds air well and resists punctures. The 2-pack is a good value for the price.
• Installation: Moderate difficulty. You’ll need to remove the tire from the rim, deflate the old tube, insert the new one, and re-seat the tire. A tire spoon or pry bar helps. Be careful not to pinch the tube between the rim and tire bead during installation.
• Common gotcha: The bent valve stem can be tricky to align through the rim hole. Lubricate the stem with soapy water to ease insertion. Over-tightening the valve nut can crack the stem—hand-tighten only.
• Durability: These tubes work fine for light to medium use. If you frequently run over sharp debris or rocks, consider a thicker-duty tube or tire liner.

Should You Buy It

Buy this if you need a reliable, budget-friendly replacement inner tube for a 4” rim tire on a wheelbarrow, lawn mower, hand truck, or small ATV. It’s a solid choice for the price, especially with the convenient bent valve stem for tight spaces. Skip it if you need a straight stem or a tube for larger rims.
