Check
www.tirerack.com &
www.whalentire.com for plus sizing info. Plus sizing is increasing the rim diameter & reducing the sidewall height, tire height will stay about the same +/-.5" (14"-17" wheel). I recommend no larger than 16's, 15's prefer. You'll start tearing up suspension, brake, power/drivetrain when you start using CHROME heavy 16's or larger.
