I bought the inner tube many months ago. It is possible that there are others there now, but the last two times I checked (within two months) they stopped selling this brand.
The tube is made with extra thick rubber on the bottom to add extra protection. It also has Slime in it. Perhaps the extra rubber is throughout the tube but more so on the bottom.
The rim tape hole is not blocking the valve stem.
Personally I don't know how having the stem not sticking out all the way would be harmful to the inner tube. Since this is the first time this has happened I don't know what could happen. That is why I asked here, because some people here might have experienced this.
The valve stem is maintaining its position. It can not be pushed down into the tire while the air is at the maximum recommended pressure.
Does the metal part of the valve stem go all the way to the tube? If it does then if there is wear around the stem it shouldn't cause a leak. I've never cut up a valve stem so I don't know the answer to that.
