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. Stop by 4Lo.com
for new and improved calculators.
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 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.
