today on our ride. my buddies tire kept coming out of the rim it wasnt going flat still aired but the sides was coming out of tire. we tried different air pressures kept happening. he asked why but its only happened to me once and i deflated then re inflated and never happened again. would it have anything to do with the profile of the rim? dumb question yes. but we dont wanna keep messing with it next ride. i searched came up with nothing.

Maybe you should add more details...

Rim size, brands of tire/rim, tire size etc etc.

These may help...? (http://www.rei.com/product/753043?preferredSku=7530430011&cm_mmc=cse_froogle-_-datafeed-_-product-_-7530430011&mr:trackingCode=868D071B-81F9-DE11-BAE3-0019B9C043EB&mr:referralID=NA) Sometimes the bead on the tires is a little difficult to seat properly on the rim, especially with kevlar and folding tires. A little leverage helps.

More details would be nice but it sounds like either the tire may be too wide for the rim or the tube may be too big for the tire.

^^ perhaps its only a misconception, but i was always taught that tire levers were only for tire removal. using anything like a tire lever to put the tire back on can easily result in a pinch flat... (you can use a bead jack (http://www.treefortbikes.com/product/333222357812/694/Kool-Stop-Tire-Bead-Jack.html), but under most circumstances, elbow grease works just fine)

deflate the tire, make sure the tire is seated properly, then reinflate. i'd wager that's the problem.

otherwise, dismantle everything, and check the tire bead and rim surface for defects. if you still can't find a reason for what's going on, buy a new tire to see if that's the problem (new tire will be cheaper than new rim). if you're sure of your tire installation ability, have a new tire, and it's still a problem, process of elimination suggests that it's the rim. consider taking it to an LBS to see if they can do anything for you, or just buy a new rim/wheel.

if you want, I can make you a handy flow chart.

Yeah, the textbook would say that levers are only for installation. But the textbook does not take your thumbs into consideration. With a little care and caution, it's easily done.

Just ball-parking and throwing out ideas for the OP.

Maybe old rims with no hook on the rim?
Can't really say without some details.
