Can a tire that blew off a rim be safely used on another rim, and under what criteria? I have a set of tires where one of them blew off the rim on my bike after I slightly over-inflated it. 

I originally asked a question about this here, and there are more details at that link. The tire did not appear to sustain major damage from the blow off, just some mild scuffing where the bead popped out over the rim. When I took both tires off after this, I did notice they're quite loose on my specific rims (easy to remove with hands, no levers required), so that's probably why it happened. 

I was thinking of posting these online for free, with an explanation of what happened, and ask that whoever takes them just state clearly to me that the know the implications of a tire blow off, they know enough about bikes and tires to determine if the tires will be safe on their bike, and will take responsibility for any subsequent injury or bike damage if the same thing happens to their bike. 

The tires seem to be in good shape and I think someone who knows bike can determine if it's safe to use them on their bike. I just don't want some noob throwing them on their bike and having the same thing happen while riding, leading to injury, etc. 

So I have a several part question:


Can a tire that blew off one rim be safely used on another rim? If so, are there any special stipulations? 


 2. Is it OK to give those tires to someone else, assuming I provide a detailed explanation of the blow off issue I had, and ask them to stipulate that they understand the dangers and know how to determine if the tires are a good fit for their particular rims? Or, should I just throw them in the garbage? Feel free to provide your personal opinion on this one, I don't think it has a concrete answer. 

 3. Assuming I'm clear about the issues as outlined above, are there any legal implications (i.e. liability for me) if someone else has a blow off and injures themselves with tires I provided "as is"? I'm located in Canada. 

Thanks.
I have a MTB where the tyres can simply be removed by hand once deflated.  The tyres are at 50~60 PSI normally.  But I can feel that they engage the clincher bead fine when inflated.

My guess is that your tyres never hook into the rim properly, and then overinflating found that area of the bead that wasn't fully seated.

As for the social side, as long as you clearly advise the recipient that you're giving them away, because they didn't stay seated properly on your rims then its the recipient's choice whether they use them or not.  I wouldn't want to see anyone hurt, but they'll be adults and can make their own choices.  Just help them to make an informed choice by sharing the history.
