yeah, is an odd size. im told the wheels were from a bmw E30 tyre fitter at the garage didnt believe me
last time i went to get new tyres. im sure my speedo is out aswell
What you need to do is change the profile of the tyre. A wheel is a wheel, the tyre fitted changes the diameter and circumference and therefore the speedo reading. Put 185/60 profiles on the 14's and you'll be good.
