Whats my speedo reading.

[nicbeer]

MM.

I have searched but all i found were coily references. I think it is about 10% out.

I have a NT (3.9) and 31's (30.8" exact).

Does anyone know what approx it would be.

(I don't have a GPS yet so I can't check it by that)
cheers

just get some on in a stadanard car to driven next to each other etc etc it also makes it easy with the small portable uhf's like the dick smith ones etc etc

there are some good tyre size calculators on the net that will tell you how far out your speedo will be. all ya need to know is the stock tyre size and the new size and it'll tell ya. only prob is you need both sizes to be in the same scale (either metric or imperial)

What is a stock zook in imperial. 26" 27"...

Borrow someones GPS

But at the end of the day, it doesn't matter how far out your speedo is. its a zook, its slow
