Heavy duty & Durable:

LotFancy 4.10/3.50-6 inner tube is made of isobutylene isoprene rubber, better than natural rubber in air tightness, elastic damping and aging resistance.
It is made of a heavy duty 4-Ply rubber. This item gives you the convenience of fixing flats without having to buy a new tire.
The metal/bent valves were just long enough to softly grasp with pliers to keep them above the rims while re-installing the tire.
Using a manual pump is the safer way to go.

This inner tube is used for:

For use in wheelbarrows, golf cart, garden and utility carts, lawn mowers, tractors, hand trucks, trailers, dollies, trolleys, yard/garden wagons, yard dump cart, snow blowers, harbor freight dolly, seeder/spreader, trike and more

Note:

Please check the size of your equipment's existing tire/tube. If it is the right size, it should work just fine.
Not for highway use.
If you never changed out an inner tube like this before, use caution remounting tire as you can easily pinch the tube and cause a leak.
