I don't like the idea of using a normal 24" tube in a 3" tire. The tube
has to stretch too much and gets too thin for my liking. I like the
reliability of having a thicker tube and a tube designed for the 3"
size.
You can use the standard 24" tube, and some people use it full time in a
Gazz, but I'd only use it as an emergency or temporary tube.
I prefer the reliability of using a proper DH tube. I don't like flats
during a ride and so far I have never had one during a ride.
I use the Intense 24x3 tubes. They're heavier and thicker than other DH
tubes.
I have gotten a pinch flat during a ride with my 26x3 muni. It was a DH
tube and it was a slow gradual leak. I only noticed the leak the next
day when the tire went flat overnight. The DH tubes do their job. I
doubt a standard tube would have been so kind.
Most bike shops should be able to order a DH tube. If you want to get
them online you could try 'WebCyclery' (http://tinyurl.com/43shn) for
the Intense tubes or 'Go-Ride' (http://www.go-ride.com/prod_tubes.html)
for the Nokian tubes.
