Metric speedometer calibration
Hi!
My tire size is 31x10.5xR15, so the conversion constant for the speedometer in miles is 918. And what about the speedometer in km/h (I live in Russia and my speedometer is in km/h - mark "0" not "E")- What is the value of the conversion constant for the speedometer in km/h for my tires size?

Today I've tried to see how many times I can recalibrate the speedometer and haven't seen any digits after the programm version (it was like that __o___03____)and when I've grounded the psom terminal the picture was the same, after I've pushed the reset button I saw 967 CAL not flashing in both cases (grounded and not grounded). What does it all mean? I don't have any tries to reset my speedo? Why I don't see the digit "0" in the end, something like that "__o___03____0_" ? If I really don't have any tries to reset my speedo, what I have to do to recalibrate it?

Speedometer recalibration.
I think you need a 1992 or later model to do this. This should work either in metric or English.
If you have a good highway where there are km markers every Km then you might be able to use the following idea...look for b4hntn in this thread.

I suspect my OEM tires were 31x10.5xR15 and the previous owner changed to P235 75 R15 so I needed to recalibrate.

Yes I'm up, not a genius, and saw your reply four hours ago. Guess you could not find a highway with km markers every km?
Oops, I just reread your original post. Looks like you have no more attempts to recalibrated left if the last diget is 0.

If I don't have any tries, why I don't see the digit "0" in the end? In my region there isn't any highway with km markers.
