YeYouC Heavy Duty Inner Tube 4-80-8 / 4-00-8 with TR87 Angled Valve

Overview

The YeYouC Heavy Duty inner tube is designed to replace worn or damaged tubes on 4.80-8 and 4.00-8 tires, fitting 8 inch rims with an outside diameter close to 15.5 inches. This makes it a versatile option for wheelbarrows, lawn mowers, wagons, carts, and other common yard and workshop equipment. The design emphasizes durability and dependable inflation, offering practical performance across a range of tasks without promising guaranteed outcomes.

Built for demanding use, the tube uses a thick natural rubber compound to deliver lasting resilience. A butyl rubber formulation helps minimize air loss and maintain consistent pressure, while the TR87 angled valve provides easier access in tight spaces or awkward mounting positions. Together, these elements work to support steady pressure and a secure seal as you use equipment from the garden to the workshop.

Materials, design and performance

YeYouC combines robust materials with a thoughtful valve layout. The thick natural rubber adds durability and contributes to a smoother ride by dampening minor shocks from uneven ground. The butyl component supports improved air retention, helping to reduce the frequency of re-inflation. The TR87 bent valve is designed to be more accessible for manual pumps, making maintenance straightforward even when space is limited.
