18" vs. 19"

pros n cons please...

For woods, I would rather have an 18". They seem to absorb a little more of the roots and rocks because of the taller profile tire. I imagine they weight a little more than a 19" though.

I've used both 18" & 19" on many different bikes. They sale enduro or trail bikes with an 18" for a reason, they work better offroad. I put an 18" on my YZF. I think they grip better, especially in roots, rocks, mud, etc. Must be more tire on the ground. On a groomed mx track, it probably doesn't make much difference.

With the 18 inch you get more tire and more "flex".

With the 19 inch you get much less "flex" which is important in MX and more importantly SX.
