wheels that can only be removed when deflated

do you think it is better to remove my brake pads or deflate my tyres if i want to take the wheels off my bike?

Deflate. Partial deflate should do the trick. Adjusting brakes is far fussier than inflating tires.

Most brake calipers have a mechanism to allow you to use a lever to open them up. Only Campy and Campy-compatible calipers don't have that because the release mechanism is on the brake levers. Are you using Campy calipers with non-Campy levers?

There are several brakes that will not allow a larger tire, even a 25 in some cases, to pass the pads. Specialized puts there chainstay brace where a large 23 will sometimes not have enough clearance for the axle to fit into the dropout.
I a have a trials bike that requires deflation to get the front tire out.

Reinflating the tire is way easier than reinstalling the pad.

In my experience, no matter what the brake type there should be a mechanism to release it so the brake will open up a bit so you can get the wheel out. Maybe this is a thing on some road bikes?

edit: rev chuck, I see, confirms it is

On my 3rensho, I've got to deflate the rear wheel just to get it past the seat tube.

There are lots of possible cases for tire clearance to be a problem when removing wheels. I've seen many mountain bikes where the tires were too wide to remove the wheels without at least partially deflating the tires. I've got an old Schwinn road bike with centerpull brakes, Shimano Exage aero levers (with a release button on the levers), and the wheels can't be removed without deflating the 700 x 28c tires...........MUCH easier to deflate/inflate tires than to mess with brake shoes-

Deflate. I have the same thing on my front wheel, I've got a Campy Centaur caliper paired with a Dia-Compe lever.

Think of it as a theft deterrent.

Are you kidding me? The brakes can be released at the caliper on the lever, or with a cable cutter. As far as theft deterrent goes, it is completely worthless.

I'd choose brake release any day.

My problem (on the road bike) is not that the wheel...or tire won't clear the brakes, because my brakes have a lever I can flip that opens the calipers so I can clear the brakes; my problem is the tire and wheel won't clear the seat tube without deflating the tire completely then mashing the tire against the seat tube to get enough room to squeeze it out. But I don't care since most of the time I remove the rear wheel is when it's flat anyways!

On my MTB I just squeeze the brakes calipers with my hand against the rim and disconnect the cable from the slot and the brakes open wide so I don't have to deflate those tires either.

I deflate. The last time I messed with brake calipers/pads while removing a tire, I messed up the brakes and couldn't use them for riding (so yes, for a while I rode the bike with only the front brake working). Besides, I carry a frame pump with me all the time now; I can inflate the tire up again later.

I deflate cause even with the QR lever open on the brakes I still can't get the tire out. I suspect the 28's i'm riding are probably 32s that were too small to pass QC as such...that or they're just some fat ass tires for the size of caliper i'm using even though they're the stock tire from Trek.
