YeYouC 4.80/4.00-8 Replacement Inner Tubes — Pack of 2, TR87 Angled Valve, Heavy-Duty Butyl

YeYouC 4.80/4.00-8 replacement inner tube is a heavy‑duty butyl rubber tube with a TR87 angled valve designed to fit 8" rims for wheelbarrows, mowers, wagons and similar equipment.

This pair of inner tubes is built for equipment that uses 4.80‑8 or 4.00‑8 (480/400‑8) tires and an 8‑inch rim (approximately 15.5" outside diameter). Constructed from thick natural butyl rubber, the tubes emphasize durability, improved air retention and shock absorption for light commercial, garden and utility applications. They include bent TR87 valves for easier pumping and compatibility with common manual pumps.

Will these tubes fit my tire and rim?

Confirming compatibility is the first step. These tubes are sized for tires labeled 4.80‑8 or 4.00‑8 and for an 8" rim; their outside diameter will match typical 480/400‑8 tires. Measure your rim and check the tire sidewall marking before ordering to avoid fit issues.

• Fits 4.80‑8 and 4.00‑8 tire sizes (480/400‑8).
• Designed for 8" rims (approx. 15.5" overall diameter).
• Verify tire sidewall marking for exact match.

How durable and airtight are these inner tubes?

YeYouC inner tubes are made from dense butyl rubber that resists punctures and holds air longer than many low‑grade alternatives. The thicker rubber improves shock absorption and ride comfort while the butyl compound enhances sealing and slow leak resistance under regular operating pressures.

• Thick 100% butyl rubber construction for strength and cushioning.
• Better air retention compared with cheaper materials.
• TR87 angled valve helps maintain a tight seal.

What equipment works with these tubes?

These inner tubes were designed for a wide range of light‑duty and professional tools. They suit common garden and utility machines where the tire size matches, making them a versatile replacement for many home, workshop and commercial uses.

• Wheelbarrows, lawn mowers and garden tractors.
• Hand trucks, dollies, wagons and utility trailers.
• Generators, pressure washers, snow blowers and compressors.

How should I inflate and maintain them safely?

Use a manual pump and do not exceed the recommended maximum pressure to prevent overinflation and damage. The manufacturer recommends a maximum of 30 PSI; routine inspections and proper seating on the rim will help ensure long service life.

• Maximum inflation: 30 PSI; use a manual pump only.
• Check valve seating and tire bead before inflating.
• Inspect for cuts or embedded debris periodically.

Who is this for: These YeYouC 4.80/4.00‑8 inner tubes are ideal for homeowners, landscape professionals, farmers and light‑duty contractors who need reliable, easy‑to‑install spare tubes for garden tools and utility machines. If you run equipment with 480/400‑8 tires and want a durable replacement that retains air well and simplifies pumping with a TR87 angled valve, this pack of two offers convenient coverage for common field repairs and scheduled maintenance.
