I noticed a comment the other day about ST tires not cracking like regular tires since they are knows to sit for long periods of time. Hmmmmmm!
I have a utility trailer with 700-15 8 ply bias tires and a 175/75-13 4 ply rated radial set on my boat trailer. The boat trailer sits in a work shop with a concrete floor, the utility outside with the tires protected from sunlight with an old barn door.
I know I bought the trailer tires in 2004 when I bought the current boat and the utility trailer tires about the same time. The trailer gets used a couple times a year to haul firewood and misc things and the boat half a dozed or so. Lots of sitting which is not conducive to forcing plasticizers out and into the tread area. (Learned of that seeing a tire mfgr's commercial.)
Both are made by SHIELD of China. Neither shows cracks of any kind. These are the only ST tires I ever owned as I used PU truck take offs on the utility trailer tires before but quit because of the sidewall deformation when turning the tandem.
Possibly more plasticizers are in fact in the tread compound and and put there deliberately on trailer tires for the given reason.
If so, what else is it and if so whooray for tire mfgrs.
