(2 Pack) RRQ 4.80/4.00-8 Tire Inner Tube with TR-13 Straight Valve Stem, 4.80/4.00-8" Heavy Duty Replacement Inner Tube for Wheelbarrows, Hand Trucks, Lawn Mowers, Carts, Trailers, Wagons and More

What It Is

This is a 2-pack of heavy-duty inner tubes for pneumatic tires sized 4.80/4.00-8, featuring a TR-13 straight valve stem. They’re designed to replace worn or punctured tubes in wheelbarrows, hand trucks, lawn mowers, carts, trailers, and wagons.

Fitment & Compatibility

Before buying, confirm your tire’s sidewall markings: the tube fits 4.80/4.00-8 tires (diameter ~8 inches, width ~4.0–4.8 inches). Check the valve stem type—TR-13 is straight and ~1.5 inches long, common on most lawn/garden equipment. Measure your existing tube’s valve position (centered vs. offset) if your rim has a specific valve hole location. This tube is aftermarket, not OEM-specific, so it works across brands (e.g., John Deere, Craftsman, Husqvarna) as long as tire size matches. Avoid using on tires larger than 4.80/4.00-8 or with different valve stems (e.g., TR-6, TR-15).

Key Things to Know

• Quality: Heavy-duty rubber resists punctures better than standard tubes, but still vulnerable to sharp debris—use with tire liners for extra protection.
• Installation difficulty: Moderate. You’ll need tire irons and a bead breaker; consider professional mounting if you’re not comfortable breaking a bead.
• Gotcha: The TR-13 stem may be too short for deep-rim wheels (e.g., some trailers)—measure your rim’s valve hole depth first.
• 2-pack value: Cheaper per tube than single buys, but test fit one before opening the second—returns are easier if unopened.

Should You Buy It

Yes, if you need a budget-friendly, durable replacement for a 4.80/4.00-8 tube on a mower, cart, or wheelbarrow. Skip it if your rim requires an offset valve stem or a longer TR-15/TR-218 stem—measure first. For occasional DIY use, this 2-pack is solid value.
