I haven't used a tire lever to mount a tire on my bike in . . . I don't know, since I was a kid and used 2 screwdrivers. Simple: #1 run rims and tires that mount easily and #2, it's just a couple simple tricks. Recently I've run Open Pro, Kinlin, and Deep V rims, all mount easily, with Michelin PRO, 4000s, Vredestein, several Schwalbe "race" level tires and they all mount easily. Some wire rims do not mount easily, but I don't run them.
