I use levers to install once in a while, to save time. But even in the shop setting, I probably use them 50 times more often to remove tires than to install. Otherwise, I might miss problems like three rim strips stacked up in the wheel, or a tire bead that’s damaged from a previous blow-off.MadRhino wrote: ↑May 16 2020 6:17amWe normally fit bicycle tires by hand alone but, do you know a single bike shop in the world that never use tire levers ? There are some (DH tires especially), that are PITA to fit on some rims without the levers.
Stiff DH tires and heavily armored tires that hold their beads wide apart can be a nuisance, and so can godforsaken “tubeless compatible” rims. But if you can get the wires into the center channel of the rim, and there isn’t something wrong with the tire-rim combo, you don’t need a pry bar to install. And when something is wrong and you do need it, it may be impossible to remove the tire without damaging the tire, the rim, or both.
