I figured out a solution. The thing that is supposed to stop the inner tube from expanding into spoke holes is called a rim tape. The tape that came with the bike is really flimsy. I'll purchase and apply a high pressure rim tape. Hopefully that would fix the problem. Update: I've decided to go for a cotton rim tape as they're more durable than rubber ...
It looks as though you're confused about the range of allowed tyres on the rim vs the tube. What connects the two is the size of the tyre you actually have. There are two independent ranges. The rim is rated to take tyres in the range 28 to 38mm wide. Your tyre will be an exact size, and ideally should be within that range. You can measure the width or ...
In my experience there is always some air loss when you remove the pump from a Presta valve, but that air is lost from the pump side of the valve. It's easier to see with a floor pump, since there's the hose to hold air. In a floor pump there's a check valve is at the pump end of that hose, and that will hold the air in the hose at high pressure even after ...
A cheap solution: regular Duc-tape works really well. Put a separate piece over each hole, in case you need to replace a spoke. I've also used it to tape the rim tape directly to the wheel when an old one broke.
Since the Presta valve closes after each pump-stroke the pressure in the hose is equal to the pressure in the inner tube. The chuck does not mechanically open the valve as with Schrader (car-type) valves. You will have to overcome this pressure with the following pump-stroke to get more air into the tube. The maximum pressure obtained in the inner tube ...
Did you inflate the tube off the rim or without a tyre? they stretch when inflated naked. Read the tube side it might be a 27.5 in the wrong box.
As well as checking for debris in the tyres, applying the patch properly etc., you need to be careful not to give yourself a "pinch flat" when you put the tyre back on the rim. This is caused when you trap the tube between the tyre and the rim, putting a fresh hole in your recently repaired tube.
