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.

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 a new wheelbarrow that has a never go flat tire, but I don’t like it ,the tire is to hard and it’s hard to push on soft soil. Got these to fix the flat tires I have ,easy to install had tubeless tires and these fit right in . Pumps up easy with the side valve. These are more heavy duty than I thought they would be . Seem to be thicker than what I’m used to and should last. So nice to have my good wheelbarrows back.

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.

These fit my hand truck. Nice they came with a pack of 2. That way I could put new tubes in on both wheels.

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)

I ordered these inner tubes for my dolly and they are the perfect size. In full disclosure, I havent actually used these inner tubes yet - instead I ordered them as a backup in case my existing dolly inner tubes go bad and need to be replaced. I cannot see why these tubes deserve any less than 5 stars, however. They appear to be of good quality so I am happy with my order!

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.

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.

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.
