RUTU 4.10/3.50-4 410/350-4 Tire and Inner Tube with TR87 Bent Valve Stem for Lawn Mowers Hand Trucks Wheelbarrows Trailers Dollies Wagons Snow Blowers Generators Go Kart Kid ATV 2 Pack

What It Is

This is a 2-pack of 4.10/3.50-4 tires and inner tubes with TR87 bent valve stems, designed for small-wheeled equipment like lawn mowers, hand trucks, wheelbarrows, trailers, dollies, wagons, snow blowers, generators, go karts, and kid ATVs. The tire size is common for front caster wheels on riding mowers and rear wheels on push mowers.

Fitment & Compatibility

Before buying, measure your existing tire’s diameter (approx. 10-11 inches), width (4.10 inches), and rim diameter (4 inches). The 4.10/3.50-4 size fits rims with a 4-inch diameter and a 3.5-4.1 inch tire width. This is a universal aftermarket part—not OEM-specific—so it works on most brands (e.g., Husqvarna, Toro, Craftsman, John Deere) as long as the rim size matches. Check that your rim can accept a TR87 bent valve stem (common on mowers and carts) and that the tire load rating (typically 150-200 lbs per tire) supports your machine’s weight. If your rim has a straight valve stem hole, this bent stem may require slight trimming or a different tube.

Key Things to Know

• Quality: The rubber is durable but not premium; expect average tread life (1-2 seasons under heavy use). Some users report minor balancing issues on high-speed machines like mowers.
• Installation: Moderate difficulty—requires a tire iron or pry bar to mount onto the rim. The TR87 bent stem is easier to access for inflation but may be tricky on tight rims.
• Common Gotchas: The inner tube may be slightly oversized for some 4-inch rims, causing bunching if not seated perfectly. Inflate to 15-20 PSI (check sidewall) to avoid pinch flats. Not recommended for high-speed use (e.g., go karts over 20 mph) due to potential heat buildup.
• Pack Size: Two tires and tubes included—good for replacing a pair of front caster wheels, but you’ll need separate hardware (rims not included).

Should You Buy It

Buy this if you need a budget-friendly 2-pack for light-to-moderate duty on lawn mowers, wheelbarrows, or dollies, and you’re comfortable with basic tire mounting. Skip it if you need heavy-duty commercial use, high-speed stability, or perfect balance—consider a pricier, branded alternative instead.
