4.10/3.50-4 Inner Tubes, 2 Pack Heavy Duty 3.50-4 Replacement Tire Inner Tube with TR-87 Bent Valve Stem for Wheelbarrows, Mowers, Hand Trucks, 4" Cart, Tractor, Yard Trailers

Quality tubes, easy installation, both holding air at 20 PSI on my dolly. See how long they hold up.

bought two sets tired of inflating tubeless every time I cut the grass, heavy duty rubber, use spoon set to install and dish soap. I also used duct tape on the inner circumference of the wheel to give some cushion after cleaning rust with wire wheel

Those small, 4 inch metal rims on many outdoor lawn/garden products eventually get rust around the rims causing the tubeless bead to fail and the tires to be flat every time you need to use them. Stick a tube inside and your rarely find them flat. They all loose air over time but its a lot easier to re-inflate a tube than a tubeless tire that is difficult to get the tire bead against the rim in order to inflate.

worked as suppose to

Great price. These tubes worked perfect for repairing my air compressor wheels. They seem to be heavy duty rubber material.

I bought these for my lawn tractor tire that was flat. After installing the first inner tube I was happy the tire inflated and I was able to use it for about a month then notice a small leak. After spraying the tire with soapy water I noticed the valve core was leaking a little bit so I tightened that and everything seemed to be fine and then a month later it was flat would not take air and it was leaking air out of the valve stem hole of the wheel. So I had to replace it again with the second inner tube that came in the order. That's now been on for 3 months and now I can't get it to hold. I even used tire and tubes he went and it still would not hold air. So basically I wasted a bunch of time and money on these stupid tires when I should have just bought a new one in the beginning and I would have been better off

Excellent service.

Good

Exactly as described. Thankyou.
