2-Pack of 4.10/3.50-4 Butyl Rubber Inner Tubes,TR87 Bent Valve Stem,High air Tightness，Heavy Duty Replacement for Hand Truck,Wheelbarrows,Mowers,Utility Wagon,and More-for 410/350-4 Wheel

The tubes in my gorilla cart stopped holding air. These were a pretty good replacement. The bent air stems are unnecessary but dont cause any problems. This was not a real easy job to do. In the future Ill probably buy a new set of tires and wheels from Harbor Freight rather than swapping tubes.

Ive fought with a slow leak for a while now and often was just runnin it lean. No longer, for this 2 pack is a flat tire repair in under 15 minutes. These replacement tubes were the exact size match for my hand truck, right down to the angled metal valve stems. Great quality tubes too, better thickness than the stock tube I removed. They even came with extra valve parts, caps and a pretty decent valve tool. Whats not to like? Nothing - all 5 stars land here.

Great replacement tires

This is a two-pack of replacement tubes that fit on my Gorilla Cart. Note that you can also get NO-FLAT wheels and tires, but this is a replacement set of tubes. Its VITAL that you inspect the tire before putting the new tube in place just to make sure the thing that caused the puncture isnt still there.

I ordered this to replace an inner tube on my heavy duty hand truck that was leaking at the valve. These are tough thick rubber, they hold air just fine, and solved my problem!

Its a tire tube and its the size it is supposed to be. Good fit. Worked great.

Product arrived in a soft envelope as you see in the photos. The kit is complete for 2x inner tube replacements on a common hand truck sized tire, but make sure you read the outside of your tire to make sure it matches the item description. I like that the kit includes a valve stem removal tool and some spare screw-in valves, but its only been a few times in my life that ive had to replace a valve, so just put it somewhere youll find it again. Apart from that, taking the old tire off of the rim is the hardest most frustrating part of the process, and the need for special tools that you may or may not have, which is where the highest chances are youll accidentally put a hole in this new replacement inner tube. I was being as careful as I thought I could be and still managed to put a hole in one of the tubes, so im a bit disappointed that im now down 1 replacement tube because it didnt survive the process of putting the tire back over the rim. But that doesnt speak to the kit and inherent value it offers, which is good. Just make sure you tires are still soft and pliable before you do this job, otherwise you might want to consider other options (e.g. complete replacement non-inflatable tires or use of tire sealing compound)

These worked very well. The rubber is high quality and they seem to last a while. Theyre not too difficult to inflate and come with everything that you might need to do inflate them! Overall excellent inter tubes. The valve seemed a little bit shaky when inflating. Not that it necessarily is bad, but it appeared that over time this might wear down.

Got this for my hand truck that had flat tires. These tubes went in good and worked perfectly. Appears to be made of good rubber.

These are well made of quality rubber and fit standard wheel barrow or hand truck tires. The bent stem makes for easy inflating.
