Probably.
The two things that kill latex are UV and ozone. Assuming they are boxed and not in a high ozone area (rare) they should be fine.
I Am I paranoid that I messed up the valve extender installation in the new wheels or this a normal amount.

A simple soap/water spray or even a water dunk will tell you the answer to this very quickly
Can you tell us more about the ozone issue? Ozone where I live (CO) has been absolutely awful this summer. Multiple ozone alerts every week.
Latex tube failed within about 10 seconds at my last race with no puncture to the tire. My thought was that I pulled too hard on the tube when I unhooked the bike pump- my pump tends to hang on to my valve a bit. But your post makes me think that maybe something else is going on.
It is a fact Jack that Latex tubes lose pressure overnight. As far as lasting, I have had “aged” 20 year old tubulars that the cotton was shot but the tube still held air. I sort of forgot about the tires I was keeping for later.
Jacob, I am guessing you messed up something in the valve stem with a catastrophic failure you had. I don’t think a month or two of ozone alerts will kill a tube, but hanging one up for a year in the sunlight and open air probably will. If you keep the tubes in a box, seal them in a sandwich bagged put them in a drawer or closet, that will keep the air/light exposure down a lot.
It is all plus and minus on tubes longevity, easy care and rolling resistance. If your racing is very important to you dealing with the problems of super fast and light equipment is just a part of the process. Now that FMB and Dugast are making 28s and 32s in their Roubaix tires, they sure are a pleasure to ride on long road rides.

I agree with Gman, atmospheric ozone is too low to be the culprit. I wouldn’t store tubes near ozone generating devices, or in a room that was being ozone treated/deodorized. The failure was probably mechanical, not chemical.
