On a bike with 700C tires I am currently running 23mm tires. Some of
the roads in Bangkok are pretty rough and my front fork could take a
25mm tire, but probably not wider, and I'm wondering whether it is
worth the effort to change from 23 to 25mm tires.

Alternately I could go a bit wider on the rear but again I'm wondering
whether that is worth while as the majority of the bumps I feel
through the front wheel and handle bars and the occasional snake bite
flat I get is always on the front.


Assuming like for like? Marginally yes, more difference in different tyres,
in my experience, be that construction or how close to stated size they
really are and so on.
