Speedo Calibration

245/75/R16 is my current size.

 

If you want to calibrate look up dakota digital, stg5??? I think the model # is. Anywho I just did this a month ago and works perfect.

Sgi-5 real part #

 

According to the calculator I would need 285s?

 

You just revived a really old thread

 

So? Sometimes it's good to consolidate threads. Keeps everything in one place for people to research rather than have 58 threads on the same thing with information scattered all over.

 

My stock 5-lug speedometer is slow by about 2.5% (reads 41, actually going 40). So if I get tires with a 2.5% larger circumference, that will very closely correct the speedometer. Right?

 

I got 33s on my 6 speed 4banger. Speed is off by 1mph in the 0-35mph range, 2mph in the 35-55 range, and off by 3-4mph in the 55-85 mph range. So basically when my speedometer says 70, gps says 73.
