I ordered a set of 4 SP9 tires, sized 215/55r17, for a blowout deal of $56 delivered, a while back.. because while I didn't need tires at the time, it was too good of a deal to pass up. I expect I will probably end up having them mounted on one of my two cars before the end of August.
Right now, they're stacked in my garage, and from what I can tell, seem to be decent tires. I know I will have no qualms about using them.
