Tubeless tires are considered safer since they have very stiff
sidewalls and tend to maintain their shape after a puncture. They
will take small punctures with a greater chance of self sealing
whereas a tube has no chance. I have had tubes (new tubes) become
partialy deflated and shred themselves under the tire bead. This
causes an abrupt blowout.
This once happened in my Sandmaster dunebuggy. The tube came out
from under the tire and wrapped around the axle sending the buggy
into a series of endos and cartwheels ending up nose-first in a
mudwash!! REALLY FUN but hard on the gear!
Contrary to popular belief, tubeless tires run cooler and heat
more evenly. This may be do to the shifting between the tube and the
tire. Also in a tube tire the air is inflating the tube that is in
turn supporting the tire whereas in the tubeless arrangement the
air is directly supporting the tire.
With either arrangement, carrying a tube is a good idea. I have
tubeless tires on my Interceptor and am about to buy new rubber. I
will probably stay with tubeless but it will depend on what tires are
available. My old bike had Metzler Perfect rear and Gordon front, both
in sport compound. I would like to use that rear but go to the new
Lazer front. I don't know if they come in tubless or will work both
ways.
