Are you sure its a true ZR2 and not a lifted standard 2 door blazer with the wheel flares added later? They did build them exactly like that without the ZR2 package. Or maybe the last owner just wanted the smaller tires. A 31" inch tire is pretty big for an S truck, and if all you do is commute it's pretty unnecessary. It almost looks like the spare is a 31" tire though.
Anyway, it looks pretty nice. The S10 blazers are really good as winter vehicles. They are perfect in snow, and can do pretty well on regular trails in stock form.
