Now that I have 37" radial Humvee tires on the M1008, my speedometer reads 50 mph and I am actually going 59 mph. That's a 20% error at 60 actual mph.
I found the add on adaptors, that go in-line with the cable. I can order one with any ratio correction I want. ($70)
Also, I assume I may be able to change out the speedometer cable, driven gear in the T-case. While researching this idea, all I find is the gears for in the transmission housing,(not in a T-case). (less than $5)
Has anyone here gone with 37" tires and re-calibrated your speedometer to indicate correctly? If so, how did you do it?
