Pros and cons of using 20-25mm inner tube in a 32mm tire? I'm using 700x32mm Maxxis Detonator tires on my hybrid road bike. Although it is possible to find wider inner tubes that could fit better that tire, the 20-25mm ones are popular and available to buy more often.

I would like to know what are the pros and cons of using a 700 inner tube 20-25mm on this tire.
I use a 700x23 butyl inner tubes (I've tested Michelin, Pirelli and Kenda) in a 700x28 tyre and I've had no problems so far. But 700x20 one is 'too thin' in this set, so it can explode. It depends on the brand and you can't rely on the assumption that every inner tube will work in every tyre.
