Yes I did it yesterday. 225/40/R18 92 H to 225/45/R18 91 W. Obvious it had a lil bit bulky face for the detriot alloy but only GTI experts notice that I guess. Driving -- It was pouring down all day yesterday and I drove around 275+ miles. Observations -- Def the ride was less jarring than 224/40. How much less is 40-60% I would say. The jiggling and throwing inside the car was reduced a lot. Please note it was not smooth like a Altima though but had a significant improvement. Next I-485 south with flexed metal roads --- def improvement. Before I was being beaten up driving this highway. But yesterday it was improved, by how much 3-45% I would say. I had Sumitomo tires and they are a good bite on this down pouring rainy roads yesterday. Improved confidence. From cornering not much difference, though for me there is a 10-15% LESS punch in extreme corners. Also I see that I miss a little bit of turbo punch feel though the speed and gear shifts are same and absolutely no difference. To consolidate, I am seeing an improved ride quality with a small miss on the punch. And the car now feels weightless at corners and absolutely no missing traction or control. Overall I am being satisfied with the 275+ miles of extreme rain day driving. I am monitoring this for another 2 weeks before deciding to change the rims from 18s to 17s and got for a 225/45/R17 Michelins.
All makes sense as that larger aspect ratio gives you more sidewall and more "cushion" so to speak.
