thats a good find Jan, works well.

I now know just how far out my speedo is with the bigger tyres on.

my tyres are original size and when the speedo on my MY03 Forester reads 108 km/h I'm really doing 100km/h according to my GPS

My LX Impreza was out about that much,
so i used one of these calculators to work out what size tyre would correct it,
and went from 185/65/14 to 195/65/15 and my speedo is spot on!
