What to check after blowing tire off rim Recently, after mis-reading "35-65 PSI" on a tire sidewall as "35-85 PSI" (in retrospect the unusually huge range should have tipped me off), I inflated a tire rated for 65PSI max to 80PSI. A few minutes later it blew off quite violently, giving me quite the fright. 

Now I'm nervous about using the tire again, wondering if it will blow off again more easily now, etc. 

So my question is a) would you generally continue to use a tire that has blown off a rim once or is best to chuck it, and b) what aspects of the tire and rim would you inspect and what are you looking for to determine if it's safe to keep using the tire? The one I mentioned looks like the rubber around the bead is a little roughed up but not terrribly so. I'll add a picture when I get home. 

Thanks.
I'd change it for a better tire, one that's much tighter on the rim. 

You inflated out to only 15 psi over its maximum. That kind of force could easily be generated in a quick turn with the brakes on. If the tire blows off in such a scenario, then you'll be underneath the vehicle you were trying to avoid. 

Go to your LBS, and explain that you want a tighter tire. They should know which tires are tighter. Don't let them argue with you, this is about the safety of your life. 

(While tires and rims are supposed to be a nominal size, some are slightly larger and some are slightly smaller. Having a large tire on a small rim makes changing tires easier, but at great risk. Hence my advice to find a tighter tire).
