Doesn't the upside down truck in the picture have 4 intact tires on it?
you can't see the right rear completely, but it may be there for eye candy

I still can't see why employees would let these things slide, I read the two stories. If I saw this crap I would climb a letter till someone cared..if no one did I would find a soap box. They are f-ing Hippocrates to call out a company and say such bad things and not make a real effort to combat or not be part of the problem
All these pics are kinda funny... as someone said earlier it looks like an outbreak of tumors!
Oh BTW said:I don't think that is true. I have Goodyear Wrangler MTR's that were on my Superduty. It's mega heavy. I had the exact side buldge seen in some of these. I linked the buldge back to tire damage I sustained when I ran over a steel stake in my back yard. It stuck up about 6" out of the ground and I forgot it was there surrounded by grass. I think I can remember driving right over it where it would have just pressed on the sidewall and tore some belting.
A couple weeks later a big goiter formed on the side wall. It's the outer layer of rubber that is bulged, it's not designed to hold air pressure. Somehow air from the inner tire migrated out to the outer layer of rubber.
I tripped over the stake while mowing the lawn and figured out what I had done. Until reading this thread, I thought my tire buldge was a 1 in a million event, meaning I thought most tires would burst with a buldge like that. I'm not running those tires anymore, I currently have hwy rubber on that truck.
OK, as someone who used to work in a tire shop, I think I need to separate the wheat from the chaff here. Most, if not all of these "defects" were cause by running over something whether in the road or off the road. Every one of the bulges in the sidewalls are caused by a "pinch". I suspect that the bulges in the tread are also from a much larger "pinch" A pinch is when a tire's sidewall is compressed to such a degree that that it gets "pinched" in between the edge of the steel rim and the surface which caused the sidewall deflection to begin with.
Imagine what happens when you hit a curb going too fast. That's what causes a
pinch.
Those bulges in the tread are likely caused in the same manner, but I'd imagine by a rock or pothole that cause the pinch to occur in the tread rather than the sidewall. It would likely take much more force to have one occur in the tread, but I can see how it's possible and obviously it is.
Take it or leave it, but most of those "defects" are not because of the manufacturer, but because of a object that impacted the tire badly.

No, all tires are susceptible, but as C4 mentioned earlier, the wedge technology that Goodyear innovated & passed around does help. If you take a good look at a Wrangler Silent Armor tire, you'll see where this "wedge" is. It really squares off the shoulder of the tire, and the added stability from the wedge of nylon toughens up the "pinchability" of the sidewall.I agree with what you are saying, now the problem is, that this means that all tires are capable of getting damaged and doing this. IS there not a brand or design that is less suseptable: radial vs. bias ply, or multi ply?
Call me a skeptic but a few of those pictures look like photochops.
What do I know though...I run surplus tires.
