Hope someone can answer my question Re;.. changing my tyres from 275X45X19 to a 285X55X19.As we all know this will affect the rolling diameter and therefore the speedo reading,(I hate low profile tyre on a 4X4.Question is in these days of electronic wizardry can the speedo be corrected by reprogramming the ECU,You see lots of cars sporting fancy wheels of all sizes, how do they cope with speedo errors etc?
