Heavy Duty Bike Tubes 700x35/38/40/43C 35/43-622 AV48 Schrader Valve 2 PCS

These heavy-duty bike tubes have worked very well as replacements for my bike tires. The sizing was accurate, and the 700x35/38/40/43C range makes them a convenient option if you need a tube that fits several common tire sizes. The tubes feel thicker and more durable than some standard tubes I've used, which gives me a little more confidence when riding on rougher roads and trails. The Schrader valves are also convenient since they work with a standard pump. Installation was straightforward, and I had no issues with the valve or fit. They hold air well and have been reliable so far. Overall, these are a good-quality, heavy-duty replacement tube at a reasonable price. Good fit, easy to install, and a solid choice for everyday riding.

Good inner tubes. Good price.

Fits perfectly. Not much info about longterm durability, but if anything comes up, I will let you know.

These tubes fit my rims perfect, they're a good value, air retention is average, quality is good and they don't leak.

These tunes worked great. Fast delivery.

They are as they should be. Heavy duty rubber with a study valve stem, ready for use. (Heads up though. They come two in a box, so they'll take up a good chunk of room in your trunk case. If you wish to only bring along one tube at a time, you'll need to figure something out for individual storage.)

Worked perfectly and arrived quickly.

I replaced an existing tire and decided that it should have a new tube to go with it. The tire was worn and a couple of years ago it had a flat that I patched. So I deflated the tire and removed both tire and tube. I checked the rim and found no sharp edges. I replaced with the new tube and tire using the handy plastic tools the tube company provided with its product. The tube does not have a max or minimum air pressure but the tire states 50 to 75 so I inflated it to 60. It held that pressure over night and the next day I set off for a ride. Everything was great but at about 5 or six miles it went flat and quickly. I walked it back to a WAWA and filled it but it went flat in about a quarter of a mile. I again walked it back and not having any tools I purchase a can of flat fix filled it to 60 and after checking several times decided to finish my ride of an additional 15 miles. Great the flat fix worked. I sat and had a lunch but when I came back the tire was flat. I was able to walk the bike to a bus line and get back home where I took the tire and tube off the rim. The leak is a tiny pin hole along the seam opposite of the valve stem. I have cleaned the tire and checked the rim and found nothing that would have made a puncture. It is my opinion that the tube was defective.

Gets the job done. Replaced my inner tubes after a few years of use which I should have done much earlier. I've had them for a few months now and haven't needed to pump the tyres at all. Previous ones kept passively leaking after a few punctures which I had to repump every few rides.
