Fitment: Universal Fit Air Filled Wheelbarrow Tire sizes: 3.50/2.50-8", 4.00-6", and 4.80/4.00-8". The 3.50-8 Tire & Inner Tube is typically used on Wheelbarrow cart, garden cart, and wagons.

Tough nylon carcass with dimpled knobs to provide traction in a variety of terrains. Open tread pattern cleans out well in muddy conditions. Our Universal Fit Tire is suitable for your handtrucks, wheelbarrows, and carts.

Before changing the tube, please check whether there are any stones or sharp objects that may break the tube and stay in your Tire.

Remember to always add a little air (to give the tube form) to the new inner tube before installing it. This will prevent it from bunching up and/or causing a pinch flat or possibly blowing the Tire off the Hub Rim (when you immediately and fully inflate) which ultimately will pop the tube.

Good Air Retention: High Butyl rubber content adds better air retention to inner tubes to prevent air leakage. Butyl rubber inner tubes can hold air up to 6 months without leaking. Traditional rubber's air permeability means you often need to reinflate your inner tubes as often as every 30-45 days.

Better Performance: Butyl Rubber Better Shock Absorption. Butyl adds more stretch, shock absorption, impact, and puncture resistance for a smoother ride. Our butyl rubber inner tubes are softer than ordinary rubber inner tubes of competitors, offering better shock and vibration absorption performance for a much smoother ride.

Aggressive Off-Road Tread: Aggressive widely spaced blocky treads with large gaps between blocks allow the tire to bite into loose soil, dirt, mud, and grass better than smoother treads.

Package Include: 2 pack 3.50-8 Tire + Inner Tube; Rubber coated valve stem with enhanced seat seal prevents sand and dust from entering the inner tube and the tire. The tough rubber stem seat is also tear-resistant to extend the service life of the valve.
