"Public Service Announcement"
Sitting at my desk here at my Shop the other night when I heard a loud hissss and then a "BANG". I looked around and found that the back tire of the 1970 had blown out. The next day the front blew out as well. I thought it was unusual to have two Tire's blow out about the same time, on the same side. Which is the reason for this post.
These are old Tires that appeared to be great condition. Fortunatly, I don't drive the Corvette other than to move it around the Shop area. I have other Cars to occupy me.
This happened just from from sitting. Imagine if you dare... if I was driving!
Be careful out there.

That is insane! I have never hear of that happening. What pressure were you using? I also noticed that you have some type of dressing (armorall?) on the tires, how long between the application of the stuff and the blow outs?The reason I ask about the tire dressing, is that I sometimes use a "fluid" to assist in the delamination of layered neoprene products for forensic analysis. ie attack the bond line. But I have never encountered your type of failure in a vulcanized product.
I also have a few vehicles with old tires and your post has me a bit unnerved
. Good thing you were not standing next to one of those tires when it went off....I would have had "the big one"Tirerack here I come....

Those are 'sidewall' blow outs...and I don't see any cracking on the rest of the sidwalls. I think you have some weak or defective tires there. As mentioned, Armor-all is a petroleum-based product and will eventually attack the rubber and weaken it. I never use that cr@p 
on my car....anywhere. Glad you weren't driving it!

Well the Eagle ST is an old tire and I don't think it is made any longer. Isn't the newer version the STII? So the first tire blows out because it is the weakest link so to speak. Then with the weight of the car shifted to one side it puts addtional pressure on the other weak tire on the outside sidewall and you get another failure.......just a guess. Get some new rubber on that nice car and start enjoying it more.

I had those same tires on my car when I bought it in the fall. They were installed in 1991.
I drove it a bit on that rubber, cracks and all a few times, but after looking at this am glad I stayed outta trouble.
Mine had the same cracks @ the correct pressure.

Definitely gonna go check my tires, although I am pretty sure you have a poltergeist in your garage.

I read article that rubber tires start to deteriorate after six years. One of the major networks aired a show about tires and date codes on the tires. Some major companies are selling new tires that are five or six years old. Tire build date codes are the week and year it was built. 3908 would indicate the tire was built the 39th week of 2008.

I have never actually heard the tire blow like this, but I have had several tires blow like this over the winter while just sitting. Yes, is does seem like the top side of the tire is the part that blows. I would recommend buying 4 new. Al

There have been threads over the last several years about old tires blowing without warning while just sitting in the garage. Looks like the warnings about using old tires are valid. Having 2 tires blow at the same time is very unusual, although if one blew it might put more stress on the other tire on the same side.
