a 205 wont stretch on an 8 inch wide rim and a 195 has a tread width of 7.6 inches, that wont stretch all that much either and with a wheel/tire combo that wide I wont be able to lower the car
spnky eg is running 195 45's on a x9 and a x9.5 A 165 has a tread width of 6.49 inches which will stretch the tire 1.5 inches. A 195 wont stretch at all onto an 8 inch wide rim because it's a 7.6 inch wide tread.
I have 205 50's now on a x7 and it looks like a monster truck tire. I don't want a tire that's gonna rub my fenders and a 225 "WILL" rub with a x8 w a 25 offset. this isn't a track car it's a daily.
195 mm = 7.6 inches = not much of a stretch.
