RUTU 2 Pack 2.50-4" 8.5" Replacement Tire + Inner Tube with TR87 Bent Valve Stem for Electric Wheelchairs Pneumatic Hand Truck Utility Cart Lawn Mowers Wheelbarrows Dollies Scooters

What It Is

The RUTU 2 Pack 2.50-4" 8.5" Replacement Tire + Inner Tube set provides a complete wheel replacement (tire, tube, and TR87 bent valve stem) for small pneumatic applications. It’s designed for electric wheelchairs, hand trucks, utility carts, lawn mowers, wheelbarrows, dollies, and scooters that use 2.50-4 tires.

Fitment & Compatibility

Before buying, check these three things:

• Tire size: Must be 2.50-4 (2.5-inch width, 4-inch rim diameter). The overall diameter is 8.5 inches, not 8.5 inches rim size.
• Axle hole: The wheel hub has a 3/8-inch (9.5mm) bore. Measure your axle diameter—if it’s larger (e.g., 1/2-inch), this won’t fit.
• Valve stem: TR87 bent valve stem is angled, so confirm your wheel’s valve stem clearance (e.g., tight spaces on wheelchairs or mower decks). Straight stems may be needed for some frames.

This is a universal aftermarket part; no OEM-specific fitment. Common on brands like Drive Medical, Pride Mobility, and many lawn mower caster wheels, but always measure your existing tire’s diameter and axle hole.

Key Things to Know

• Quality: Solid value for the price—treads are fine for light-to-medium use (paved surfaces, light gravel). Not for heavy off-road or continuous high-speed mower use; sidewalls can wear faster under heavy loads.
• Installation: Moderate difficulty. You’ll need to mount the tire onto the rim (can be stiff), inflate the tube, and ensure the valve stem doesn’t pinch. A tire lever helps. No special tools required, but patience helps.
• Common gotchas: The TR87 bent stem can interfere with some wheelchair frames or mower decks—test fit before fully inflating. Tubes may need slight deflation to seat properly. Check that the rim’s bead is fully seated to avoid wobbles.
• Tube included: Yes, each pack comes with a tube, so no separate purchase needed. But tubes are standard 2.50-4 size, so you can replace with any compatible tube if needed.

Should You Buy It

Buy this if you need a budget-friendly, complete wheel replacement for light-duty applications like a hand truck, utility cart, or electric wheelchair on smooth surfaces. It’s not ideal for heavy lawn mower use or rough terrain, but for the price, it’s a reliable, easy-to-install option for most 2.50-4 applications.
