Here's pictures how my summer 20" setup looks like. It's a concave wheel, but with 8,5" and ET like that (40) it's hard to notice. Would really want 21" set, but couldn't find 8,5" with correct ET. Went for 245/45 tire which has +4% diameter (original size with 20" is 245/40). This way wheel wells are looking more occupied and the car looks lower (while it's actually a bit higher). Also should add to the ride confort on gravel roads (which I have to drive) and made speedometer spot on with GPS speed. On the downside it adds to unsprung weight (compared to 245/40 tire), but my wheels are only 10,6kg/pc, so compared to original wheel/tire set it's not that bad. My winter setup is also the same size, but with studded tires and a bit heavier wheels (8,5", ET38 IRC). Car is 2016 2.0crdi 4WD AT.
