Check your tire dates!!

Seems like tires dry rot faster than they did in the past, anyone else think that? Or am I being anecdotal.

My local friend is very brave, just pumped this old spare to 35 psi. lol

I asked a guy that I know who works at a local tire dealership about tires wearing out now due to age. He said that one reason is because the tire manufacturers don't use as much real rubber in modern tires anymore. To get better mileage and wear and to make the tires stronger they use more "other" ingredients instead of the good, old fashioned rubber from rubber trees. Sounds reasonable to me.

This was my old post from the 70 hemicharger thread back in 2008: https://www.yenko.net/forum/showthre...t=77085&page=8

Remember: Tires Expire!

I was cleaning out the Charger to get ready for a show today and found these photos from a few years back, in the console. This tire was one of a set of BFG radials that were 14 years old with only about 500 miles on them.

I was driving to a cruise night one afternoon when all of a sudden the steering wheel ripped out of my hands and spun to the right. It would repeat this every 10 feet or so. I pulled over and found nothing. So I rolled along and it started doing it again. I stopped again and couldn't find anything wrong.

Thinking I was either hallucinating, or the poltergeists/gremlins in the car were trying to persuade me to go home, I ignored them and slowed down but kept heading to the cruise night.

Seeing that I ignored the two previous hints from the Almighty, He decides to use a more direct approach: As I kept rolling along slowly, out of nowhere a Minister, dressed in his black "going to church" suit drives up alongside my car and says: "Son, pull over there is something wrong with your left front tire."

So I pull over and he gets out of his car and says to keep rolling until he says stop. He yells out "STOP" and I stop right there. We both look under the car and the enormous bubble in the sidewall is wedged against the tie-rod end, at the bottom of the tire's travel.

It seemed that the internal failure of the tire would let air out into the sidewall when the flawed spot would hit the pavement. When the tire rotated, the air would suck back into the tire. (Kind of like the old Little Rascals episode with the cake that has the rubber glove in it that goes WEEE-WAAAH )

The bubble was so big it was hitting the suspension and forcing the wheel to turn right.

Here's the tire:

And the bubble:

When we dismounted the tire, the bubble stayed in the sidewall for about two weeks, slowly deflating back to its original shape. I drilled a hole in each tire's sidewall and threw them away (so no-one would try to reuse them).

So let that be a lesson. Don't ignore the hint when God sends you one (or three).

I think I read somewhere that the lifespan of a tire is 7 years and any tire older than that should be thrown away. That's pretty good advice.
