I cannot access the tire gear & speed calculator

It doesn’t calculate for 1/4 mile statistics, nor is that what I want.
You can plug in:

tire height,
Rear differential gear,
transmission gear
RPM
And/or travel speed
Any 4 of the five
and figure out transmission and rear gear combinations for the street and highway.

I am not seeing that in the 50 Wallace calculators.

Calculate GEAR, RPM, MPH, TIRE DIAMETER

I really am not understanding why you're having issues. All of these calculators can help you reach what you're looking for, I believe.......which of course as always is as clear as mud.
