These tires were put onto the my OEM 19" S-line 'Y' wheels today. I was worried that these 225s would be too narrow on the 8.5" wheels; but as you can see, there tires are still wider than the wheels, so I am somewhat relieved.
Car rides like a dream after these tires were put on; much quieter/smoother than the Dunlops performance summers 255/35 R19 that came stock. The Dunlops were getting very hard these past couple weeks when the temp hovers in the low single digit; and they were transmitting all the road imperfections through the shocks and into the cabin. I haven't had any (fingers crossed) vibration issues with either the stock tires/S5 wheels setup (last pic) or this Blizzak/Y wheels setup. As expected, the tires is further into the wheel wells because they are much narrower than before.
With the Blizzaks, my rolling circumference increased by about 3.6% over stock. I have a Tomtom GPS and the car's speedometer after the Blizzaks were put on is almost spot on vs. Tomtom up to about 120 km/h (car's speedo is consistently slower vs. Tomtom by about 1 km/h at higher speeds). This implies that the car's speedo is too fast by about 3% with the stock setup, which is kind of consistent with the common knowledge that most car manufacturers calibrate their speedometers to show a higher-than-actual speed. So increasing the rolling circumference actually made my speedometer more accurate and besides, having thicker sidewalls don't hurt in the winter either.
