I'm looking for some advice regarding tire and tube maintenance for long distance touring. I'll be staring my first long unsupported trek in a couple months and want to make sure I'm prepared, but also do not want to overpack.
First, what is your method for keeping up on tire pressure on a long tour? Do you use car style pressure gauges with a presta adapter to check pressure? Just do the pinch test? Where do you like to fill up on air?
How many spare tues do you bring? I was thinking one or two spare tubes and vulcanizing patches. That way could swap the tube quickly on the road, and repair the punctured one later.
Do you like to bring a spare tire if touring long distance and unsupported? Have you ever needed to use it?
