Maximum Possible Tyre Size For A 1.40 Rim?

[vel_tins]

Hello,

i want to upgrade my 60/90 "bicycle-tires" to the maximum possible Size.

I know, a 2.75* or a 70/90 would fit, but I would like to use a 80/** Size.

Is it possible on my 1.40* Rims?

thanks

Sorry for the new post, but I couldn't edit the previous..Why? Time Limit?

EDIT: on a philipino board, I read, some people mounted 80/80 on a 1.40'' rim, so it seems to work.

Anyone have eperiences with this combination?
