Perfect fit!
I was needing to replace the tubes on my wheelchair wheels. I’ve been doing a lot of research and study on which brands and types would be the best. When I receive these, they’re well-made, very sturdy, and have a great feel when you’re in the chair. Definitely something I would get in the future when needing to replace bike tires or wheelchair tires.

Not well made, will last 7-8 weeks on a wheelchair on average
Update 12/31/24:I am not going to delete what I wrote, but I was totally wrong. The tubes are fine. My punctures were caused by the sharp edges of the spoke holes on the inside of the wheel. To smooth this over, you need something called "rim tape". I paid $5 for some at my local bike shop and taped up the rim. I think this will fix my issue! These wheels came with solid rubber tires on them, and I did not know about rim tape. It makes total sense now so make sure you get some if your wheels are not taped on the inside!Avoid these tubes for daily use. I purchased four, and within 15 weeks, two failed due to ruptured seams which is likely a manufacturing flaw. Luckily I was home both times. While they might work for occasional use, they’re unreliable for regular use. I’ve resorted to patching them temporarily but plan to replace them with better-quality options. Don’t rely on these if you need dependable performance.About every 1.5 or 2 inches around the tube are these little elliptical seams (see photo). I don't know what they are for but I assume it is some artifact of manufacturing. Both tubes failed as pictured when one of these seams ruptured and deflated the tube.
