I pretty much keep my Trek 730 in the trunk of my car when not riding, by removing the front wheel. But to get the front tire (32-38mm widths) past the brake pads, I have to disconnect the brake cable from the brake, to increase the gap between the pads. It's a hassle, and would rather not have to mess with the brake cable ... or deflate the front tire ... with my new bike if I want to carry it in my trunk.
My new bike will have Shimano 7801-SL wheels, and Shimano BR-7800 dual-pivot caliper brakes. The wheels are 20.8mm wide and 24mm in height. A lot of technical tests of the 7801-SL were done using 23mm wide tires, so I'm led to believe that Shimano had the 23mm tires in mind when they designed the 7801-SL.
But I'm thinking about using tires wider than 23mm, so here is my question: When removing the 7801-SL wheel from the frame ... and through the Shimano BR-7800 "Dual Pivot Caliper Brake" ... does anybody know the maximum tire widths that I could have on the 7801-SL wheels ... where I would not have to deflate the tire or disconnnect the brake cable to remove the front wheel? The Shimano website does not provide that information.
