Importance of "H.E." rim designation on MTB to tire fitment? I'd like to convert an MTB with 26X1.95 knobbies to road use for the wife but wonder if the present tire designation, specifying H.E. rims means anything once proper size tires are found. Many thanks!
I suspect "H/E" means "Hook-edged". This would apply to almost every MTB rim.

I have two bikes with slicks on MTB rims. I currently use Schwalbe Kojak 26 x 1.35" on one, and Schwalbe Marathon Racer 26 x 1.5" on the other.
