i am currently using a 19c wide rim 700c size but need to update my wheels to accommodate disc brake rotors.

i was considering to get wider rims because my tyre of preference is 50mm wide.I have noticed though that most if not all wheels i see are 19c wide for normal qr scewers. When i find wider rims like 25mm or 30mm im then totally confused by all this terminology about boost and thru axle sizes.Is it then a good idea to stick with 19c wide rims if using qr scewer or to perhaps buy an adaptor for such wider rims like a 15mm to 9mm convertor.I have had punctures when going to high pressure on current rims so now i limit to 40psi which seems fine.if i go to 60 its like forcing the tubes into the holes in the rim causing the tubes to tear even though the max tyre pressure is 70psi.

In the "Rear bicycle hub" article's section 5.1, I've explained the standards of "boost hubs" (while the nuts&bolts standards article lists the thru axle threat pitches).

Yes, the very wide rims usually come with boost hubs (and "thru axles") - partially for marketing reasons, partially for making laterally stronger wheels.

One solution would be to relace the existing hubs with wider rims. Other solution would be to find a combo that can take adapters for quick release (some boost hubs are too wide and won't fit).

Tubes tearing on spoke holes is probably caused by no, or poor quality rim tape - see the article "Bicycle rim tape explained" for more details on how to pick a high-quality rim tape (a...

Hope this helps. Let me know if you have more questions. :)
