I'll be darned- an actual "this spare blew up on the rack" post!
I just asked this question in the last few days in response to a fellow's dark assertion that it's happening all over the place, but only with ST tires.
Was the blown tire an ST? And if so:
Is it your opinion that the tire blew up because it was an ST, or do you think it was in any way related to its ten years (plus?) of exposure to the elements and might have blown regardless of type?
Yes, it was an ST tire.
Yes it blew right there on the rack (after 10 years on the rack, 50 miles under the trailer, and THEN being returned to the rack)
Yes, I belive that the design of ST tires makes them prone to this type of fialure. (However, I have had tread separation on old bias and on 'regular' radial tires so it's not as simple as we want to make it that ALL ST tires suck and ALL regular tires are wonderful...)
Yes, I belive the figure that tires (all types) are engineered for about a 5-year lifespan. While it was covered for most of it's 10 years, it did face all the temperature fluctuations...
So, I can't complain that it blew on the rack, but have a utility/farm trailer with 15 year old regular tires on the rim on the trailer on the ground that are not covered in any way shape or form with much more than 50 miles on them, and none of them have spontaneiously failed at the 10-year mark while sitting there....
