Mission Automotive Replacement Tire Inner Tube - Flat Repair Lawn Mower Wheel & Garden Cart Inner Tube - Pack of 2, 10 Inch, Fits 4.10/3.50-4

What It Is

This is a pack of two 10-inch replacement inner tubes designed to repair flat tires on lawn mowers, garden carts, wheelbarrows, and similar small utility vehicles. Each tube fits tire sizes 4.10/3.50-4, making it a direct swap for the original tube inside a standard 10-inch wheel.

Fitment & Compatibility

Before buying, confirm your tire’s sidewall markings. This tube fits tires labeled 4.10/3.50-4 or 3.50-4 (the “4” is the rim diameter in inches). It will not fit tires marked 4.80/4.00-8, 5.70-8, or any 8-inch or 13-inch rims. Common machines that use this size include most walk-behind push mowers (e.g., Murray, Troy-Bilt, Craftsman), garden carts, and small trailers. No OEM-specific part number is required—these are universal aftermarket tubes. Measure your existing tube’s valve stem length if you have a deep rim; the included stem is standard straight rubber, about 1.5 inches, and works with most rims.

Key Things to Know

• Quality: Made from butyl rubber, same as OEM tubes. Users report good puncture resistance for the price, but not heavy-duty for commercial use.
• Installation difficulty: Easy—remove wheel, deflate old tube, pry tire bead off rim, swap tubes, and reinflate. A tire spoon or flat screwdriver helps. No special tools needed.
• Common gotcha: The valve stem can be too short for rims with deep center holes or raised center hubs. Check clearance before buying. Also, over-inflation (above 30 PSI) can cause stem tearing.
• Pack of two: Great for replacing both rear wheels on a mower or having a spare. Not for front wheels on zero-turn mowers (usually smaller size).

Should You Buy It

If you have a standard 10-inch lawn mower or garden cart tire that keeps going flat, this is a reliable, low-cost fix. It’s ideal for DIY homeowners who want a quick repair without replacing the whole wheel assembly. Skip it if you need a heavy-duty tube for commercial mowing or if your rim requires a longer valve stem.
