flats without punctures?
I just bought a '92 xt and on the 8 hour ride home I had two flat tires on the rear wheel. After the first flat, I checked the tire and found no nails/thorns/etc. I had the tire patched (using spare rubber from another tube and rubber cement, TZ style)and remounted everything and filled the tire up to 26psi. Oh, I also ran my hand along the inside of the tire to make sure there were no abrasions; there were none. Four hours later I got another flat. After taking off the tire I saw that a: there was a brand new hole, and b: the original patch had started leaking. There were no nails or thorns in the tire. I have maybe 15kg of luggage and am driving over pretty decent tarmac at 110-120kph.
Why is the tube getting holes? What can I do to prevent this? Keep in mind my nearest access to tubes and tires is several hours away.
