Is this tire okay?

I've ran them that way and never had a problem. Don't know what causes them to look like that. I say run it.

 

Its an air bubble caused by separation. It might run just fine or it could blow at sometime down the road.

 

I have same on my Bridgestones ...over 100k ...no problem so far

 

Divit in is a over lay in belts. Divit out is a broken belt. Failure at some point.

 

flip it on the rim and forget about it lol

 

I was always taught that an inward depression on the sidewall can be considered a part of manufacturing and a normal appearance. Outward bulges are considered broken belts or separation, however minor. There are likely hidden punctures that have broken the cords. Internal inspection often reveals alot.

Its proly not long for the world under fully loaded application.

 

Next is the buldge between sidewall and liner. Then kaboom!

 

I had a kaboom on a driver last week at high way speeds loaded. You just never really get use to that sound. Roger.
