Check any tyre brand chart to convince yourself. They explain allowed and recommended tyre sizes per rim sizes. I did not find anyone which allow what you are doing. 110 on 3.5" are allowed but not the opposite. Anyway I'd stick with the recommended fitting. That is why I will try a 170 rear by the way.

not sure the 170 will gain any benefit apart from slower turn in. I did fit a 150 on an ER5 instead of the 130 and that was far better though. The 190 on the Bird feels much the same as the 180 too. Give it a go, that's how we find what works and doesn't. The 120 works for me. I still prefer the Roadsmarts to the currently fitted 023 especially in the wet.
