Aged Tires: A Driving Hazard?

Me and my friend were talking about how long tires sit around before they are sold.

He sent me this video over aim and i thought i would share.

I didn't watch the vid as I'm on my fone, but the biggest things that effect tires that are not in use are how they are stored and exposure to uv light.
Tires should be stored on the side, allowing the whole tread to absorb the weight instead of standing up with the weight concentrated on one spot.
Uv light breaks down the elastomers in the rubber, making it stuff and susceptible to cracking and early, uneven wear.

Either of these things will ruin a tire, but it takes a while. Tires are made pretty strong and will last a long time when stored correctly. If you buy an old set, check the inner liner by pusing down on it as you roll it around. Look for any irregularities inside, any cracks on the bead area and shoulder of the tread. Once they're full of air check the sidewalls and tread for any lumps, hollows, or unevenness in the center of the tread. Radial tires hold their shape remarkably well, any imperfections are probably from the factory, and if its a new, quality tire it should be free of any of these signs.

Good write-up. I saw the news report when it aired, and they said 7 years max. So a lot of people that use their spare, maybe surprised how old it is. I would think a tire place would have a high turnover for common vehicle tires. However, most blow-outs occur due to bad maintenance and such that I don't think it is as big a deal as the news makes it out to be.

wow...i guess that means i HAVE to get rid of my gumbo mudders that have no dry rot and look like there new.....and there from 1983......ive had those tires on the truck previously cruisin for 3 hours on end at speed in excess of 75mph, if they were gonna blow out, thats when they would have, truck tires are designed to last alot longer then a car tire which will usually NEVER reach the 7 year mark

Blow outs happen for many reasons, few of which occur outside of the manufacturing process. Unless you're talking about nails debris punctures etc. Improper mixing, using the wrong type of rubber, weak joints the list goes on. That's why michelin tires cost so much More.. To cover the quality control cost. Same with bridgestone, they're like Toyota and Honda of tires.

This video is the typical media bull **** scare tactics

1. the guy bought the tires when they were 4 years old....at the time of the crash they were 9 years old. That means he had been using them for 5 years. At an average of 15k a year they had about 75k on them and were about to blow anyways.

2. The tire treads on the side of the road are from semis with retread tire. Those tires are illegal on passenger cars in this country.

3. They want to make the tire manufacturers for old tires, when its the distributors fault for holding them that long.

4. "The number was printed on the inward side of the tire" 99% of tires have the numbers printed on both sides. And most tire have a non directional thread and therefor can be mounted with either side out

5. These tires can be called brand new. If you bought a toaster from a store, that was made in 2001, what would you call it? Brand new or old but still in box? I know I would call it brand new.

Yes tires become less elastic with time but like a fellow member stated a lot of the items discussed were one sided. The tire they showed was probably some knock-off brand. How come people can't take responsible for their own choices? He had a choice on whether to check those tires or not...Heck at being 9 years old who is to say they weren't low on air or leaking air?

I had some conti's from TireRack.com and they wouldn't balance worth a crap. The tech started to inspect them and noticed they were right at 6 years old. Tirerack sent some new ones but that's an easy way to tell. I mean those conti's vibrated at 15 mph.
