YeYouC Heavy Duty 4.80-8/4.00-8 Inch Replacement Tire Inner Tube, 4.80/4.00-8 Innertube with TR87 Angled Valve for Wheelbarrows, Mowers, wagons and More for 4.80-8 4.00-8 480/400-8 Tires Pack of 1

What It Is

This is a heavy-duty inner tube designed to replace worn or punctured tubes in 4.80-8, 4.00-8, and 480/400-8 tires. It fits wheelbarrows, lawn mowers (walk-behind and zero-turn), wagons, garden carts, and other small utility equipment with those tire sizes.

Fitment & Compatibility

Before buying, confirm your tire’s sidewall markings. This tube fits tires marked 4.80-8, 4.00-8, or 480/400-8. It does not fit 4.10/3.50-4, 4.80-12, or 5.70-8 sizes. The TR87 angled valve is designed for offset rims or deep-dish wheels where a straight valve is hard to reach. Measure your rim diameter (8 inches) and tire width (4.00–4.80 inches). This is a universal aftermarket part, not OEM-specific, so it works across brands like John Deere, Craftsman, Husqvarna, and Cub Cadet as long as tire size matches.

Key Things to Know

• Quality: Heavy-duty rubber resists punctures better than standard tubes, but still avoid sharp debris. 4.4 stars from 273 reviews indicates reliable performance.
• Installation: Moderate difficulty. You’ll need tire spoons, a pry bar, and a compressor. The angled valve can make seating easier on some rims but may require deflating to insert through the rim hole.
• Common gotchas: The TR87 valve stem is short (about 1.5 inches). Ensure your rim hole is large enough and not blocked by a hubcap. Over-inflating (max 40 PSI) can cause bulging; stick to 20–30 PSI for mowers.
• Size note: This tube fits both 4.00-8 and 4.80-8 tires, but a 4.80-8 tire will stretch the tube slightly—still safe, but avoid using it in a 4.00-8 tire on a 4.80-8 rim (too loose).

Should You Buy It

Buy this if you have a 4.00-8 or 4.80-8 tire on a mower, wheelbarrow, or wagon and need a durable, budget-friendly replacement with an angled valve for easier access. It’s a solid value at $9.99 for most residential and light commercial use. Skip it if you need a straight valve or a tube for non-8-inch rims.
