Folding tires haven’t been the problem for me that certain rims can be.

I got rid of Torelli Master rims because they were so incredibly difficult with tire mounting/dismounting. Particularly so at that tourist overlook above Florence, Italy with many bus loads of people watching!

The Mavic Reflex/Open Pros, tb14’s and Pacenti Brevet (in 650B) have all allowed tool free dismounting after first installation of folding Grand Bois and Compass tires.

Then there were the Velocity rims that were so loose that I could never get GB tires to mount evenly.
