I know this question is really compound specific............

I've started storing tires (F1G3) in a storage building. It can get quite hot, especially in the summer (9 months here). It can easily get up to 150F+ on a daily basis inside of the unit. As a comparison Tire Rack's heat cycling service raises the tire temp to 170-180F.

I really don't think the storage will be an issue and damage the tires, particularly on the non R version, but would appreciate thoughts/experience from those that have stored tires.

TIA

I would suggest emailing goodyear customer service:
https://corporate.goodyear.com/us/en...corporate.html

That storage facility sounds like it might be too hot to me.
This is a good technical question and deserves a good technical response.

excellent idea, just did.

Did they respond?

Actually, yes. They responded a few days ago and I've been busy.........appreciate the reminder.

This is the response from customer service. It's not specific and doesn't address "heat cycle" directly. The last couple of times at the track I was asking folks what they do and their experiences. No one seemed concerned, a lot of folks leave the tires in their trailers where thy are exposed to elevated heat. Is it extreme heat

From GY:
The best place to store tires is in a clean, dry, sunless area away from strong air currents. Even though the rubber used to make tires is formulated to resist effects of sunlight, ozone and water, the life of a tire can be extended if exposure of these elements is minimized during storage.

Stack tires flat so that the bottom tire will maintain its shape
Wrap each tire with an opaque polyethylene covering to minimize the effects of oxygen and ozone. Most Goodyear retailers have storage bags made specifically for this purpose
If tires are being stored outdoors, they should be raised off the storage surface
If tires are being stored while mounted on rims, they should be inflated to 10 psi
If they are put in storage during warm weather, the initial inflation pressure should be about 15 psi to offset the pressure drop during cold weather months

How Not To Store Your Tires

Don't store tires in an area that is wet, oily or greasy
Don't store tires where they are subject to direct sunlight or extreme temperatures
Don't store tires near electric motors or other ozone-generating sources
Don't store tires on black asphalt or other heat-absorbent surfaces
Don't store tires on or adjacent to highly reflective surfaces such as sand or snow

That's not such a great answer, as I'm sure they have a performance/racing division with specialists who know all about heat cycling.
I don't follow NASCAR, but Goodyear was an official supplier only a year ago.

There is a lot of good information there, especially the "opaque polyethylene covering"; honestly would not have thought about that for a shield.

I wish they would have gave a temperature for the "Don't store tires where they are subject to direct sunlight or extreme temperatures"

Thinking about this, there are two aspects to tires "cycling out" of grip capability:
1. The amount of grip and release, adhesion then shearing and/or ripping, to a surface.
2. The cycles of heating to the compound.

"1" is part of the cause for "2". The other part ("3") is friction between construction segments of the tire structure, but not really related to the grip reduction.

In your scenario, you aren't doing "1" and you aren't doing "3" (however heat does effect the integrity of the tire structure).

I can tell you that the SC 3 (not R) does not seem to be effected by winter storage in a typical Mid-West/Great Lakes garage... They are also known to be able to take a good amount of heat and last quite a few sessions/heat cycles without much grip degradation. The SC 3R is also known to do well in respect to heat durability and grip longevity.

With that in mind, I think the tires may be OK, but I would be a little concerned if they are left to near 170F and above for long periods of time. I find it hard to believe the inside of the building is 150F+ 24/7... for 9 months?

To be fair, OP did say temp can "get up to 150," which is not the same as staying there 24/7. With the right kind of sun exposure and a non-insulated roof, I bet it could easily get there in some months.

Apologies, I was a bit flippant

I suspect that it easily gets to 150F daily and cools off to 75-90 over night most of the non winter here. Each day of storage could be thought of as a heat cycle.
I like and do agree with your logic that 1 & 3 would have a stronger influence on the compound degrading, loosing grip.

Due to space constraints, I'll store be storing tires and we'll see if I can tell a difference. Also, I'll approach a few GY dealers to see about some storage bags.

Amazon has 8 for $16, shoulda known
