Depends on the rim too. I have a pair of campy wheels that are just barely concave. Impossible to get tires on without levers.
About 30 years ago I built up a set of wheels using Campy Ypsilon Strada rims. Combined with 20mm Specialized Turbo R tires, that was a guaranteed broken 2 or 3 levers getting the tires installed.
The reason I even had those rims is that I had a customer bring them in, to get a wheelset built up. He came back about a week after picking up his wheels, complaining that he got a flat on the road and could not get the tire off, broke both his tire levers. Said he didn't want the rims, and paid to get his brand new wheels rebuilt with some Mavics. He didn't want the Ypsilons back, so I used them on a pair of hubs I had sitting around. And realized right away just what he was complaining about... :)
