O.K., go, explain exactly what an apex is, and how the condition pictured is “apex separation”.
The apex is the extruded rubber which cups the bead and connects the bead to the sidewall. It’s extruded so there needs to be a splice where the two ends are pressed together to mate. When the tire is cured if a splice is under/over cut there leaves a weak spot. Apex separation is when this splice becomes opened up which is seen best in pic 3. It was probably caused from poor installation, which put excess stress on the weakest point.
You posted about 20% correct information. The other 80% is grossly incorrect. When you are done taking your foot out of your mouth I suggest you click on my user profile and look at “occupation”.
Lol think what you like, if you would look at the picture it is very apparent.
And whats parts of my statement are incorrect?
Fairladyd-bag is just getting his balls scratched on the interwebs. Just click to ignore him, it’s way easier than talking to a know it all.
Lol well thanks for the heads up.
OP either way I wouldn’t run the tire, you could try talking to the installer to see if they’ll do anything for you.
Yes, it is very apparent. It is apparent that the core bead is exposed on the inside diameter of the tire (bottom of the bead).
So what is missing or displaced to expose the inside diameter of the bead? The chafer (toegaurd) and ply (or plies). The chafer is part of the inner liner, the shit that keeps air in the tire. The ply is part of the structure of the tire, the shit that keeps the tire intact.
Looking at the first picture the right side with the hanging piece looks like damage from a tire mounting machine. This damage was deep enough to cut through the ply (or plies). This would initially compromise the structure of the tire. 30 psi isn’t a “big” number until you start to deal with large surface areas, so let’s stop here and say that this initial damage was 2" long. A 225/60 will have a 5.31" tall sidewall, + 8.86" width, + 5.31" side on opposing side (where the individual cords from the damage ply are secured around the bead). 38.96 square inches @ 30 psi = 1168.8 lbs of force acting laterally on cords that were no longer wrapped around the bead and no longer secure on one side. The breaker package may negate some of these internal forces.
Looking at the first picture on the left side there is tearing consistent with the initial damage growing from internal forces. In the fourth picture there is a bulge in the sidewall from the displacement of the cords. Over time this tear will grow and a blowout would occur.
Now the apex. The primary purpose of an apex is to add cornering stiffness to the tire (not to connect a bead to a sidewall, and not for structural integrity). A tire with high cornering stiffness will produce more lateral grip at lower slip angles, great for sporty tires. However too stiff and ride quality is compromised, not good for getting groceries or taking kids to soccer practice. Depending on the plies used and application of the tire it is possible to build a tire with no apex at all. But you say apex separation caused the anomaly pictured?
Did the stuff on the outside and bottom of the bead end up on top of the bead after it was all said and done? Sure, but that is not apex separation, that is because there was a lot of force displacing a lot of shit.
For those of you that would mount this for burn outs, drifting, and other hoonage consider this. There is a section about 5" wide of 5.31" tall sidewall ply that is not locked around the bead. 26.55 square inches @ 30 psi = 796.5 lbs of force, that could go off at random. It could go off when you mount the tire to the rim, it could go off when you are hand tightening the lug nuts, it is unpredictable. A party balloon weighs about 2 grams, and blows up with about 1 to 2 psi when it explodes in your face. A tire weighs 25-30 lbs and 30 psi when it explodes in your face.
I stand by my first post. I do not recommend using any tire with an anomaly such as the one pictured.
Enough with the fancy talk. Do a burnout with this tire already.
