A wider rear tire should not make your rear feel unstable or loose. the whole point of more tire in back is for more traction back there
if they're brand new tires they'll take a couple weeks to break in and burn off any protective gunk on it that might be left from the mfg
that said, we don't know anything about the condition of your fronts. given that you have a 2016 they should be pretty good still
