140 means there is a sizable patch of meat on the ground, and 80% of 140 means 112mm of sidewall height. That's in the same league as a 120/90 or more common tire.

I replaced my rear with the same 140/80, but was wondering about it as I don't see this tire size that often.
Should I go to a more common 120 or 110?

I ride mostly technical trails - a good bit of rock here in central texas - and race
hare scrambles (C class).

I just got this email
