Axle Ratio/Tire Size Calulator 1.1
Here are a few calculators that may be useful in deciding tire
size, gear ratios, and other stuff. These should be compatible
with Netscape 3.x and MS Internet Explorer 3.x or above.
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 (assumimg 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
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
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.
