Axle Ratio/Tire Size Calulator
1.1
Ever wonder how far off your speedometer
is with your new bigger tires? I'm using a simple ratio calculation,
so this info will only approximate
your corrected speed and depends on the accuracy of tire size diameters
(assuming nothing but tire size has
changed).
Now that you have your truck lifted,
you want bigger meats. They look cool and have the potential of being
very functional, but they may also
be robbing you of power/gas mileage. This calculator will get you back
to a ratio that's closer to your original.
Enter the values on the left and press Compute.
Ever wonder what your low-low-low
gear ratio is, your "crawl ratio"? You'll need to do a little research
by finding
out the transfer case and transmission
ratios first. Enter your values on the left side, press Compute and
your answer will be on the right.
I've spend a bunch of time trying
to WAG (wild ass guess) my actual MPH when going down the road. By knowing
your gear ratios and tire size you'll get a more accurate idea here. Enter
the value on the left, press Compute.
I suppose if you don't have a
tachometer you could use this form, otherwise it's only useful to find
out how
accurate your Tach is. Enter the values
on the left, press Compute.
This formula is a nice way to
get the tire diameter of those metric tires that are common on just
about everything stock. For example
a 265/75R16 would be around 31.6 inches tall. Enter
the numbers into this form in the
order you read them from the tire and press Compute.
