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

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!

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.

I like how these tubes fit my small wheels, with the valve stem accessible

We use our Gorilla cart all year to keep up with projects around the yard. Right now it is in need of a new inner tube. This will fit perfectly. They are well made and sturdy. Gotta get ready to start rolling around the yard for Spring planting.

I bought these to replace the tubes on my UGV, and the sizing seems accurate and so far they are holding air well. They seem a tad thinner than the tubes that came in the tires I have, but so far they are holding air well and they seem to be decent quality. I will update if they start to leak or if they fail, but so far so good! Im quite happy with these. I dont buy tubes like this often, but at $12 for the pair at the time of this review theyre a good value.

Great for revamping for spring! Works great!

These are so easy to install. They seem to be very durable. One tool required to install these.

Had two air compressor tires that had a slow leak, so I installed these tubes inside each tire which didnt take too long and held air with no leaks. This was a cheaper and easier alternative to keep the tires inflated vs buying two new rubber tires.

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.

I got these because I needed a tube for a garden trailer and for the cost, I figured I would give them a try. While I havent put them on yet, simply from opening the packaging I can tell that these are well made and will do the job just fine. For me at this price and given you get two tubes plus three extra valves and a heavy-duty valve wrench, this really is a no-brainer. I can repair my cart, use one of the valves to repair a bad one on my snowblower, and have reserves on hand, all for $12! If you need it just get it.
