For what it's worth, my speedo is more accurate now with 31's than it was with stock size tires

 

Here's a good bit of advice. Buy a gps. Garmin units have a built in speedo....which I use on my setup to keep in check .....here's my results....

3 inch lift
31 inch tires
3.55 gears
Auto

35mph no difference
55mph odometer 58mph actual
61mph odometer 65mph actual


Gps is more accurate than radar

Stick that in your juice box and suck it

 

But you just proved my point... 61 speedometer 65 actual... Which I basically said with 60 speedometer and 65 actual.

When did an odometer read speed? Interesting

Blow it out your nose :P

 

I agree, also we can't think that our 17 year old speedos are that accurate anymore.
