Stock wheel width vs. tires?

[douglasskemp]

I own a used 2015 LTZ with 17" stock wheels. I am wanting to upgrade the tires (tires ONLY not wheels) since my RF has a slow leak anyway. It came with 205/50R17s and ideally I would like to go up to 225/45R17s since they are VERY close in height (https://tiresize.com/comparison/ shows only a decrease of 3mm) so as not to screw up any sensors. The only thing that I am curious about is if the OEM wheels can safely support an increase in the width. I use it as the family car too, so if it is too much of a PITA, then I will just put 205/50R17s back on it. I tried to look around for some answers, but I don't know exactly what to search for and I got tired of looking for it when one of the threads I was directed to has over 700 replies and another one had over 2000. Thanks!

As someone with that exact size on their 2012, I can't possibly see why not. I doubt GM switched to a thinner rim on the second gen.

Yes, I had that size on factory RS wheels.
