Don't do it unless u want ur rear wheels to sit about 2" further in than OEM ZCP wheels. Or u can always run spacers/adapters that 1.5" thick (30-35mm). Even if u were to run a fatter tire, u would still need at least a 20mm spacer. And u probably don't wanna go any wider than a 285 on a 9.5" wheel.
Btw, this is just MY opinion
