my tire safe? slighly bent inner bead - UPDATED PICS

I had a picture, but you can't tell from the pic..

Anyway,

Long story short, I had a "flat" tire months ago - due to cold weather - right before i took my summer wheels off (19" rims, 265/30 in the rear)

... I had to drive literally a block a half to fill the tire.

When I took my wheels off for winter, I did the usual visual inspection.

Upon looking at the tire that was "flat".. i ran my hand along the inside edge of the tire bead, and it is a little "wavy" ... no bubbles, just slight waves in it, like the metal bead inside the tire got bent a little.

..tire looks fine, no rips, or bubbles, no metal or anything like that sticking out, holds air fine, and like I said, couldnt even tell from the pics i tried taking. the "difference" in change of the "waves" is probably less than a 1/4" inch from high point to low point.


Is my tire safe to put back on? It is FINALLY starting to get nicer here in the Northeast and I am itching to put my wheels back on...

Hard to tell without seeing in person but best bet is getting a new tire. From what you are describing it seems that the sidewall structure has been disrupted therefore you risk a blowout. Better safe than sorry. Somebody correct me if I am wrong

Nobody can know remotely. Better safe than sorry on this one. If you can see/feel defects, just trash it.

I am going to try to post the pictures later today... you literally cannot tell from the pics though... atleast I can't.


The "wavy" part of the bend is only about 4-5" long... so its not like the entire tire is bent like this the whole way around.

I am no tire expert - could this "seemingly small issue" really cause a blowout?

...Only blowout I ever had was in highschool and that was due to camber (lowering springs) and the inner tread of the tire go so bald and exposed the metal inside and caused a blowout - i was driving back to college at the time and was even planning on getting new tires when I got there... well i got that, on back on a roll-back truck though haha.

Definitely going to need to see pics of your tire before deciding.

Also, to go back to your high school experience, it sounds more like toe wear than camber wear. If your toe is in spec, your tires will last a decent amount of time.

Those are bubbles. Replace the tire.
