*WARNING* For My 22" Tire Owners...

I've ran 22's for years and I've also used several tire brands: Pirelli, Nitto, Toyo and currently Hankook.
I am very attentive to my rides, maintainence and safety. Monitoring my tire pressure once or twice weekly! These extra low profile tires are impossible to visually tell they are too low or even flat!

So I had been having a slow leak in one of my rears that had no puncture. I initially contributed it to the varying temp changes lately. But decided to take it in to have the tire dipped to see where the leak was coming from. Upon dismount, there was a very obvious issue:
On the very inner side near sidewall, seperation and steel belt was visible.
Even though my tread is in great shape with thousands of miles left! No cupping no camber wear, nada!
The cause.... Weight Load exceeded.
They explained that they see this mostly on large diameter tires on luxury cars like mine. In fact, the air was leaking from there! Get this, the other side was worse!
So I drove back home and promptly installed my stock 19's which are like New. And THIS ladies and gents is exactly why I refuse to sell my stockers on any car I have. Unforseen shyt happens like this and no local shop has 22's on hand typically.
So after investigating weight ratings for these heavy ass cars, you generally want to be in the 100s. My Hankooks were 97. As are most 22s. So be careful and I suggest either jacking your car up or removing tires for a full visual even if the tread looks great! Ironically, fronts were fine. So lesson learned.
Now for frightening pics:
Note the nice tread and then on the inner side... Seperation that could've led to a BLOW-OUT!!!!
