How do you fix a loose bicycle tyre? By loose I mean the tyre came off the rims due to

riding when no air in.? Not all of them came loose, just some. But severe enough that the part that came out covered the brakes.

I have to carry my bicycle down and up the stairs everyday so I suspect it came loose due to repeated impact with the stone steps. Any way I can prevent this from happening other than carrying the bicycle higher?

Tires are of correct size and are fully and properly inflated when it hit the steps.

Bicycle was bought from Wal-Mart (I know, they suck) which explains why it does this so soon after I bought it, really.

unless you provide photos, it's hard to tell whether or not you have the correct tire on the rim.

if you keep the tire inflated to the recommended inflation pressure printed on the sidewall, the tire shouldn't come off the rim.

also, don't ride the bike without air in the tires.
