what is the biggest tire I can put on my 2013 Impala with the stock 17 inch wheels

I went with 235/55/17 filled fender gap well,was afraid that the 50 series would create more gap while providing a little more width to be seen Fromm front or rear view, it pays off to research the brand of tire you decide to install, was surprised that every manufacture listed the same size tire with different dimensions, also I went with the General G Max and couldn't be more happy with them, they changed the handing over the Goodyears and improved ride quality or at least to my standards I like to feel the road in my steering wheel hope this helps people out because I had no luck with dealers to help. Not like the good old days when they would mount one up and let you see how it fit.

2006 buick lacrosse 225 55 17 is my size will 235 55 17 fit my car
