I've got toyo RA-1's on my 15/16's right now, and my rear are in worse shape.... i expect these hoosiers would be sticker than the toyo, which i understand can be a bad idea to mix tires, but would it be all that bad a match since it'll be sticker on the rear instead of the front? I imagine it's a really bad idea to run disproportionately sticker tires up front...
