I was going to put this on the wheel forum, but think more will see it here.

Learned a hard lesson, yesterday, while making my second drive in my 64. Never dreamed it could happen! If it's something you don't know, maybe it will help others. I sure didn't!

Around 10 years ago, while the 64 was being painted, went to Discount tires, and got a set of BF Goodrich tires mounted on my wheels. I've bought from Discount for many years, and keep in mind, what I'm saying is good for any brand of tires.

About halfway of the drive, to where I was going, on the interstate doing 70-75 mph, started noticing some kind of vibration. What the heck? Couldn't pick out where it was coming from. I was a little over a mile, from where I was going. With all the heavy traffic, high speeds, decided to ride it out, and look things over off the highway. Then...BOOM...front right tire had completely blown out! A new tire, with only 700 miles on it, no spare, no jack, and 108 degrees outside.

Long story short, had the wife bring me what I needed, to get the wheel off. That tire had lost every square inch of tread on it! Took the wheel, back down the road a couple mile, where a Discount tire was. The guy looked the tire over, looked at numbers, and told me the tire was too old! Told me any tire over 8 years old, is considered 'unsafe".

Had no idea on that one. So, I'm looking at having to replace all my tires! When the tire let go, it also did some damage to my right front fender. Probably going to have to pull it, to get it straightened.
 
I've heard of the 7-8 year timeline on tires also. They can look just fine, but shouldn't be driven. But then again, I know of knuckleheads that drive around on 25 year old rubber without batting an eye. Good to hear nothing serious happened to you or your car considering it was in heavy traffic at highway speed.
 
I know my tire shop says 6 years on trailer tires. Does anyone know how to decipher the numbers to tell the age of a tire? Would be good to know so you don't end up with a new tire that's already 2-3 years old.
 
As long as I've been driving, and fooling with cars, kinda hard to believe I've never been told about that. Yeah, hard lesson...
Only thing I knew for sure was dry rot. Car never sat in the sun, so tires looked good.

Just have to deal with it.
 
A less experienced driver might have gotten themselves in trouble, especially in our old cars. Glad it all worked out.

I was reading that it’s even worse when our car sit. Apparently when we park our cars for extended periods of time plasticizer evaporates from the tread and sidewalls causing dryrot to start and creating a very brittle rubber.

I understand that driving down the road helps the tire distribute the plasticizers throughout the rubber, allowing a tire to stay plyable much longer.

Last 4 digits of the DOT number displayed on the sidewall of the tire, for example 2518 would be the 25th week of 2018. That’s the date the tire was manufactured
 
Glad it all worked out.
Thanks! Got the car pulled over, and stopped okay, thanks to good brakes. Really lucked out after I started walking. A young lady with her baby had seen me, and the car. Actually turned around, came down the service road, and honked her horn. Walked over, and she said she never gave anybody rides, but the car looked so cool. She was kind enough to give me that ride, so I could call my other half. 109 degrees, dang near 70, and bad legs, I was glad to get it!

No spare? Mainly, because I have been looking, not enough, for another 15" police rim.

Plasticizer? The guy at Discount simply said the chemicals used in the tires, would leach out over time, the 8 years.
 
That's terrible, glad it didn't turn out worse ! 5yrs is the mark for me, then I start looking for tires. Actually in that boat now with my dart... you van never judge a tires condition by looking at the tread, always look for the DOT date on the sidewall. It's a hard pill to swallow replacing tires that still look new but are "old" , but the consequences far out weigh the price of new rubber !
 
Just had a good look at my fender...:mad:

Worst than I though, tread doing some hard hits. Crumpled the bottom front of the wheel opening some. Bottom rear of the opening, completely caved in, as far as it could go. And, insult to injury, tread 'rode' halfway down the lower part of the door, leaving tire scuff marks.
Will have to pull the fender, for sure. What a frigging bitch.
 
BFG blowout on this Challenger took out the quarter. 10 year old tires. I just pulled the tires on my 65 and replacing them.Tough pill to swallow.My tire guy sure does like me though...

I've been into cars for 31 years. Former ASE Master Tech. I've never been educated on a tire timeline aside from the mentioned dry rot issues, and flat spots and shifting belts. Thanks for the story and the date code info... Good to know.
 
I had a similar problem 2 years ago. Highway speed, slight vibration I could not pin point that slowly worsened. SAME TIRE, maybe slightly older, but didn't blow (belt separation). This time she rides on Cooper Cobras.
 
A good point made in this thread. Our daily driver vehicles "use" the tires, so we are likely to replace them before the "expiration date." However, on the vehicles that we do not drive that often, do not accumulate many miles, those tires begin to deteriorate in ways we do not see. The same aging concern applies to belts, hoses, vacuum tubing, wiper blades, weatherstip, wiring, etc. Vehicles are more happy when driven.
 
Just had the rear blow on the way home from Carlisle 275/60/15 redline that was 2 years old .
The heat ,distance travelled all played a factor in it .
Butttt , my spare also blew that was an unused brand new tire that was sitting in the trunk for
10 years so the story is also check your spares .
Lucky no damage to my car .
 
In the motor home world if you do not move for a month you should take the weight off
also park on plastic or wood not concrete as it draws the oils in the rubber or some thing like that
