I once ran 225/55R17 tires on Acura TSX 17x7 wheels with 55mm positive offset. Stock offset is 50mm. That was not much of a game-changer in terms of handling.
Later, I ran 235/50R18 Pirelli Scorpion Verde tires on 18x7 wheels with 41mm positive offset. The vehicle just seemed a little less stable as that 9mm offset change meant a noticeable change in scrub radius. I had also lowered the van just a tad by use of H&R Sport Springs. The cornering was tremendously improved, but ride quality was not as good. Also, it was a larger diameter setup, and it did have a noticeable effect on acceleration and MPG
Knowing what I know now, I should have gone with a set of old school Acura TL 17x8 wheels (45mm offset) with 245/50R17 tires. Only 5mm offset change, wider footprint, same rolling diameter, etc.
