This thread makes me want to cut open a few dry rotted tires and inspect the cords.
I think that Ozone scale can be misleading, depth of said cracks is key. 2mm is not a lot. How deep until it actually reaches the cord? That's what I want to know.

I would be very interesting in seeing what you find, it wouldn't take very long to cut one in half to check things out. Is there an inherent disadvantage or advantage to having tube tires? Are they "safer" than tubeless? Oh Stumps where are you....

Tire Aging
Dear Tire Doctor,
Can storing a vehicle on concrete effect the tires? Should I put barriers like plastic or other non-porous material under the tires? How about the effects of continuous storage for several days at a time with use between storage periods?
Thanks for your help on this subject.
Best Regards, Len
Dear Len,
Thank you for contacting Bridgestone and allowing us to assist you.
First of all, regarding the effects of storage:
A cool, dry, sealed garage is your best condition for storage, however, it is realized that this is not often an available option. Concrete is not the tire enemy some people think it is.
We would recommend the following steps in storing a vehicle:
1. Make sure the floor / ground surface is free of any petroleum product contamination (Oil, grease, fuel, etc.) since petroleum products will attack rubber and can cause significant damage to compound characteristics.
2. Thoroughly clean your tires with soap and water.
3. Place a barrier such as plastic, cardboard, or plywood between the tires and the ground surface.
4. Cover your tires to block out direct sunlight and ultra violet rays.
5. Do not store the vehicle in close proximity to steam pipes, electrical generators or animal manure since these accelerate oxidation of the rubber.
6. Make sure your tires are fully inflated with air.
7. When the vehicle is ready to go back into service, inspect the tires for excessive cracking in both the sidewall and tread area and check all tire air pressures. Tires will normally lose about 2 PSI per month so you should expect to find the pressures lower than when you put the vehicle into storage. Re-inflate the tires to the correct air pressure before operation.
Now, about the effects of time:
Yes, rubber compound does slowly change over time, becoming "harder" as it ages. But unless we are talking years, this would be virtually undetectable. However; the most likely effect of storage will be:
1. Flat spotting of the tires from taking a 'set' while sitting in one position for an extended length of time. This 'set' may work itself out of the tires after being put back into operation, but not always. This, of course, would result in a vibration.
2. Tires have waxes and oils specially formulated to protect against ozone damage built into their rubber compounds. When the tire rotates and flexes, these waxes and oils are forced to the tire's surface and are thus able to protect the tire. When a tire is stationary, these waxes and oils are not coming to the surface and thus the tire is at greater risk of ozone damage.
3. Several days of non-use at a time is not nearly as detrimental to tires as long storage periods. The tires would still be operated often enough to avoid excessive 'set' and the waxes and oils are being forced to the tire's surface often enough to provide adequate protection against ozone.
Best regards, Tire Doctor

Dear Tire Doctor,
How long can a tire be stored?
Sincerely, Miguel
Dear Migeul,
Thank you for the opportunity to be of assistance. You ask a question that is very difficult to answer in absolute terms.
Generally speaking, there is no set "storage life" for a tire. The acceptable length of storage will vary according to a number of conditions.
Is the tire mounted on a vehicle?
If mounted, is the tire supporting the vehicle's weight, or is the vehicle jacked up off the ground?
Is the vehicle stored indoors or outdoors?
If stored outdoors, are the tires covered to prevent exposure to the sun?
Are the tires stored close to steam pipes or electric motors?
Does the tire see any use at all - even short trips - during the storage period, or is it left sitting in the same position for the entire time?
As you can see, there are too many variables to state a maximum storage life for a tire.
If it is any help, Bridgestone's warranty expires (6) years after the date of manufacture.
If you have tires you need to store, we recommend the following suggestions:
1. Store mounted on the wheels
2. Remove the vehicle's weight from the tires (put vehicle on jack stands)
3. If at all possible, store indoors, away from electric motors and steam pipes
4. If possible, periodically drive the vehicle a few miles to allow the tires to flex, this allows the tires to force to the surface the ingredients included in the rubber compounds that inhibit oxidation.
5. If you have to store the vehicle outdoors, cover the tires so they are not exposed to sunlight.
6. Before operating after storage be sure to check the air pressure.
7. You may wish to consider nitrogen inflation - nitrogen does not seep through the tire as quickly as air, plus it prevents moisture and oxygen (which cause oxidation) from seeping through the tires.
8. After a long storage period, have your tires inspected by a qualified tire technician.
We hope this has been of some use in answering your question.
Best regards, Tire Doctor

Just hope you don't have to deal with these folks.
Georgia Worn Tire and Inadequate Tread Depth Attorneys
Tires are perhaps the most important part of any vehicle. Only a few inches of tire touch the road at any given moment. Worn tires cannot properly grip the road surface, which can cause a driver to lose control on a sharp curve, to spin out during an evasive maneuver, or to hydroplane on wet pavement.
Tire wear can become an issue in a personal injury or wrongful death case in two ways:
When a maintenance failure, such as checking for tire wear, has caused or contributed to the crash
When a tire retailer or reseller sells a tire that should not have been sold because it was too worn or too "old" to be safe
Wrecks can also be caused by defective tires.
If you were hurt or a family member was killed in a Georgia car or truck accident, contact an Atlanta worn tires attorney at Butler, Wooten & Fryhofer, LLP, or call 800-233-4086 for a free case evaluation.
The Atlanta personal injury attorneys at Butler, Wooten & Fryhofer, LLP, have significant experience holding negligent drivers, manufacturers and retailers accountable for the harm they've caused. We have a proven record of success securing top-dollar verdicts and settlements in car and truck accident cases. Our firm has played a key role in litigation against tire manufacturers such as Firestone, Michelin, Goodyear, Cooper, Dunlop, BF Goodrich and Hankook.
Tire Wear: How Old Is Too Old?
There's more to a tire than just tread depth. Tires become less flexible and less safe as they age. The tire materials themselves break down over time, especially when exposed to heat — like the heat of a Georgia summer. Excessive heat causes tires to age prematurely. This can cause unexpected tire failure.
The age of a tire and how it was stored before it was purchased can affect its quality. Even if a tire has never been used, it may not be "new."
We have experience investigating car and truck accidents to determine if a product or component of the vehicle was defective or improperly maintained. We work with experts in design, engineering and manufacturing to get the facts.
Our Atlanta truck accident attorneys achieved a significant settlement for a family in a truck accident case in which a mother died and her 8-year-old daughter suffered brain damage when a truck slid out of control in the rain and hit their car. The truck's rear tires were excessively worn and the truck's driver had warned the trucking company of the problem that morning, but was told to drive anyway.
