I know they make 205 for 17". But the 205 in the tire code is that tire width right? How will a 17x7" rim then fit, when 7" in mm is 177.8mm not 205mm. Or is there just somthing i'm not getting here?
I thought the second number, for example 17 x 7.5 is the offset. And offset is the distance from its hub mounting surface to the centerline of the wheel.
