I was installing a tire after I got a flat yesterday (sealant was dried up). Anyway when I was airing up the tire it blew off the rim so, I installed a new tire and seated it and now it appears as though the rim is bent.

I was wondering if blowing a tire off the rim would result in a bent rim?

The bent rim may well be why I got the flat in the first place because, the flat right after I hit a deep rut. I couldn't find any leaks so, I aired the tire up and rode a few more miles only to have it go flat again which is when I discovered the sealant was dried up (I was experimenting with a new sealant which clearly doesn't last as long as Orange Seal).

Any thoughts?
