So you went from 215 to 235.

This is my upgrade. Similar increase in size. But mine is a simple Mazda 5.

OEM tires: OEM Toyo PROXES A18 - Size: 205 / 50 R17
New tires: Pirelli Cinturato P7 - Size: 225 / 45 R17

OEM rims were 17 x 6.5 with an offset of +52.5
The new rims are 17 x 7 with an offset of +45.

I got a wider rim to accommodate wider tire sizes. It does not sound like much but it makes a big difference. Most cars come from the factory with skinny tires ... probably because fuel economy.

BTW, I think fuel economy is worse, but I never even paid attention to that in the first place...
