  Very few bicycle components can actually be repaired; replacement of the failing component is the normal practice.
  
  The most common roadside problem is a puncture. After removing the offending nail/tack/thorn/glass shard/etc., there are two approaches: either mend the puncture by the roadside, or replace the inner tube and then mend the puncture in the comfort of home. Some brands of tires are much more puncture-resistant than others, often incorporating one or more layers of Kevlar; the downside of such tires is that they may be heavier and/or more difficult to fit and remove.
