Gear help.

Just a guess gang... What gears would make the speedometer read 70 and my GPS say 60? 1 to 1 drive gear with no overdrive. 235/60/15 tires.

I am guessing 388s round about. It is geared for pulling at 55. Has the granny low 4 speed in her. She has a lot of power for pulling but really starts to scream around 60 mph.
