Nice product, description is accurate

I have a Gorilla cart that developed four flat tires. I repaired two by patching the inner tubes, but two of the four original inner tubes had multiple holes. Rather than repairing those, I replaced them with these and they fit perfectly. I’ve had them in for a couple months without any problems.

The tires on our hand truck were sometimes inflated and sometimes not. I thought about getting some of that patch inflation spray, but am glad I didn't. As I took the old innertubes out, I found they were leaking from the base of the stem - they didn't have something simple like a puncture. These were a breeze to install once I realized each rim of my handtruck was two half rims bolted together. For me, it was much easier and safer to remove and redo four bolts than to muscle such a small and thick tire with some screwdrivers. So far, these are holding up great. The stem is bent so that the place you would attach the inflator pump is at a right angle to the plane of rotation, that is, the stem sticks straight out from the wheel. Hopefully, this will have less wear on the stem than my old ones, but you probably want to make sure that it won't matter to you to have the stem stick out about the height of a stem cap from the outside edge of the tire.

These comments are no reflection on the quality or design of the inner tubes. You would think that putting tubes in a 4.10 x 4” tire on plastic wheels shouldn’t be much harder than thinking about it. You’d be worng, but once you figure out how to do it, the second one takes about 1/4 the time. I bought a 3200 psi pressure washer from Costco several years ago. It came with tubeless tires, so almost every time I rolled it out of the garage, the tires were flat. It was a pain in the butt to get air into them. For instance, I fought filling them in May, putting a little extra air in. Last week, August 10th or so, went to use it again, and both tires were flat again. So, I had bought the tubes, and was ready for battle. I used bicycle/motorcycle tire irons to get the tires off and on. I needed 3 irons to get the tire off, leaving the first one in place to keep the tire bead at the starting point, then alternating the second 2 prying the bead off in steps until it rolled off the rim. I didn’t take the tire completely off. Then, once the tube was inside the tire, I found if I clamped a Vice Grip pliers on the rim where I started rolling the bead back over the rim, it kept the tire bead from following my efforts with the tire iron around the rim, and only one tire iron worked best in the reinstallation. In the future, the tire pressure may be low after sitting through the winter months, but with tubes it will be a cinch to air up the tires, instead of fighting the beads back on trying to seal them long enough to hold a little air.

The initial quality of this product seemed superior to tubes that I have purchased in the past: thicker rubber, quality seams, and good protection around the stem where exits the wheel. They were carefully and properly installed on the front tires of my zero turn mower, then inflated to just under 40psi (the recommended max for the tire). Both worked great initially, and completely held air for about a month and a half (about 5 mowings of my 1 acre yard). Then, I came out one morning to find one tire completely flat. Filled it up, and it lasted half a mowing before totally flat again. I replaced that one with another brand, just to have my second original tube on the other tire do the same thing 2 weeks later. Upon inspection, neither was a small pinhole... the tubes seemed to simply burst at random locations (see the attached photo to see what I mean). I know they weren't knicked or damaged during installation, because I was very careful and used a good tire lubricant during assembly, along with smooth/rounded/plastic tools. Maybe this was just a bad batch of rubber or an old lot, but I wouldn't take the chance again.
