LukiYuChen 4.10/3.50-4 Inner Tube – Heavy-Duty Replacement (2-Pack) TR-87 Bent Valve

Rugged, reliable 4.10/3.50-4 inner tube replacement

The LukiYuChen 4.10/3.50-4 inner tube is a heavy‑duty replacement crafted for common off‑road helpers. Designed to fit tires sized 4.10/3.50-4 with a 10 inch outside diameter, this pair features a TR‑87 bent valve stem with an air cap for controlled inflation and steady seating. Built from durable rubber, these tubes are made to withstand the daily demands of garages, yards, and job sites. A 30 PSI maximum inflation keeps the tire shape predictable, while the bent valve provides easier access in tight spaces.

With durability in mind, the tubes are long lasting and designed to resist leaks when seated correctly. The 2‑pack gives you a ready spare, so downtime is minimized and you can keep working without delay. This set is clearly labeled for off‑road use and is not intended for highway vehicles, but it delivers dependable performance for garden, workshop, and utility equipment.

The robust rubber construction aims to provide a reliable seal over many uses, reducing the chance of frequent flats when used with compatible tires.

• Check both tire and rim for damage before installing a new tube
• Inflate slowly with a manual pump to a safe limit of 30 PSI
• Ensure the valve seating is clean and the tube is evenly seated inside the tire
