Re: Travel Speed
Mark,
Remember overall diameter of the tire affects the final gear ratio. So, with a taller tire, you have a higher gearing(lower numeric).
I seem to remember, although don't quote me.... that 1" of tire height changes the final ration about 0.250of a rati.o.
So, in that big bad Dodge of yours, if you ae running 3.55's in the diff with 31" tires, and switched to a 32" tire, it would have the affect of changing the diff ratio to 3.20's.
The taller tire will make you go faster. But, the change will take away a little of the bottom end power. Talk to anyone who put big tires on a 4x4 truck without regearing; they are sluggish off the line. they also go to fast in most cases for slow "creeping".
There are some formula's which will calculate it if you know your tire diameter, gear ration, rpm, ect
