Yeah, but truck tire treads are everywhere! I picked up one and brought it home and figured I'd put my old carbide tablesaw blade out of its misery. It was an old Freud 60 tooth that had lose several teeth. One pass across the piece of tread stripped off the remaining teeth! Funny thing is, even without the teeth it still cut the steel cord, though it was smelly and not something I'd recommend.
Try a metal cutting abrasive blade in a skilsaw or table saw. Once you cut through the steel cord plies the rubber cuts easily, although it's a bit smelly!
The rubber would probably do a good job absorbing some of the higher frequency mechanical noise that could otherwise telegraph through your I-beams. I ended up not using them because the studs I welded to my frame weren't long enough to get a nut and washer on the stud with the rubber beneath the engine, and I built up the fillet around that stud so heavily I didn't relish the thought of all the cutting and grinding I'd have to do to remove it.

Plan first, weld later.
