Do tires get old?

[sc72]

Bias ply tires, if you lived in a cold state like Iowa, you would get in your car first thing in the morning head to work and they would be flat spoted, the tires would thump till they got warmed up, talk about a Flintstone ride.

Lots of info to start here, you can check around at the above site and find more info as well.
I worked at firestone for 9 years, we destroyed any tire on the shelf that was 3 or more years old, we drilled 4 - 2" holes in each sidewall. If age was not a factor I don't see why they would destroy that many tires. Our store alone would toss about 100+ tires a month.

You mention firestone for a tire recall, not fair as dang near every manufacturer has recalls.
You can search by brand for recalls here:
http://www-odi.nhtsa.dot.gov/cars/pr...callsearch.cfm
or just google "tire recalls by brand" a huge amount of reading.

Aging is a big factor in tire safety, ever see those nice cracks all over the sidewall? They really show when you let the air out, these are due to aging, a brand new tire left in the sun, never mounted will dry rot/crack badly. It's all in the rubber components breaking down.

Aging is a big factor in tire safety, [/QUOTE]



I don't think you read what I posted and further, your statement that aging alone is a big factor is not supported by scientific study or legislation.

Despite intensive testing by the Feds to PROVE that tire aging was a significant risk factor in tire safety, the best they can come up with to date is, "they're not sure or to what extent". You can bet that if they come come to a solid conclusion (which was their intent all along), legislation would have quickly come out of the testing results. To date, AFAIK, the only legislation was to require tire pressure sensors on new cars starting, what, last year?

I also pointed out that Firestone has received the vast majority of the bad publicity for tire failures and tire safety over the last 50 years. I didn't say anything about "recalls".

Having been the once proud owner of three different sets of Firestone 500's and another model I can't remember that literally shredded themselves apart on the highway, I'm somewhat qualified to name Firestone as a major culprit. Oh, and these failures were before Firestone was FORCED to recall the tires. I received no reimbursement from the for the defective tires. The tires were not old either. Less than a year.

Another one of their fiascos was the Wilderness tires that failed on the OEM Explorer vehicles. A fiasco that cost me many dollars probably in Company dividend loss. These tire failures involved were partly the result of heat and low inflation pressure. I'm told, the major contributor was poor workmanship in the manufacturing plant, both from a plant worker there and in an official context. Age was not a factor here.

Lastly, if your tire store destroyed any tire in the store on a monthly basis over three years old, I'm surprised they stayed in business. I'm further surprised that a store in an environmentally conscious area like Oregon would care to see their landfills spilling over with perfectly good tires.

I don't miss those days at all!!

Look at those links and do some searching there you will find the studies and reports that verify aging being an issue. NHTSA has done alot of studies and tests.

As for the above qoute. I worked at Firestone, destroying that many tires a month will not hurt them let alone put them out of business. Tires are just small portion of there overall business.

Landfills spilling over?? really? tires do not go to landfills here it's against state law, they are recycled and reused in many many different capacities.

The legislation for consumer protection is actually in progress in a number of states, it was first introduced in california (2009).

This is one of those subjects that could go back and forth forever.
You have your opinion and I have mine. I can respect that.
Have a nice Easter

This is what you're missing. I never said "aging" wasn't an issue. I said "aging alone" has never been proven to be an issue. And, it still hasn't been. Underinflation, overloading, poor repairs, manufacturing defects/workmanship and other abuse have DEFINITELY been shown to be big contributing factors.

So let's do something about the things we KNOW cause problems.

Any organic matter that sits around long enough will decompose back to dust.

My concern is that if people talk about something long enough and loud enough, some enterprizing polictician will pick up on it and get some very, very costly legislation passed with little to no benefit to the paying motorist.

Those guys are just like dogs running around the yard, hiking their leg to mark their spot and put their name on something and a whole lot of worthless legislation gets it's start right out there on the left coast.

So what he's saying econoaddict is if a set of tires has been sitting on a shelf for 10-15yrs, he'd be willing to put them on his vehicle, pile his family in and hit the road with them and isn't worried about the tires failing. Because no one has proven to his satisfaction that "aging alone" is an issue.


Mike McKown,
Of more interest to me is how do you define "aging alone"?

Your reference to bias ply tires isn't relevant. Bias ply tires didn't wear nearly as well as current radials so they were replaced more often and with less miles on them. So I suspect they never sat on a shelf very long before someone needed them.

I didn't say anything even remotely similar to what you're quoting me as saying and the "aging" thing hasn't been proven to anyone despite long and exhaustive testing, not just me.

My reference to bias ply tires is very relevant. You didn't use to have the same type of castostrphic failures with them as with steel belted radials. Rayon/polyester radials didn't seem to have the same kind of probelms the steel radials do either.

A four ply nylon or rayon cord tire used to last 15-20K miles. When the tread wore out, if the casing hadn't been punctured or abused, the casing was re-capped and run another 15K miles or so. In some cases, they were re-capped a second time. So, you could conceivably get 40K miles or so out of the casing. About the only problem you'd see with them was occasionally, a hole in the casing would let air leak in under the cap and cause a bubble on it and blow the tread off. Still the casing itself didn't blow out.

hey does anyone know how to store tires if your not going to use them for a while?
