Dub, you should consider the Scan Guage becuase you can program it and have it read out your actual speed.

I'm sure you are loving that locker. Putting the Aussie in my Trooper made a HUGE difference offroad.

Yep...7.3% is what I get on the Miata tire calc when using your tire size vs OEM.

But you know me well enough to know of my eternal skepticism of the accuracy of everything...

So I have no choice but to do a road trip while Hunny keeps track of the mile markers...

Also, when calculating (on intrweb tire calcs) the difference between stock & 35's, I found a 1-2% discrepancy in their % values.
I'm sure they use a baseline calc, & there are certainly differences in actual size from one manufacturer to the others. Possibly due to tread depth etc.
When I switch over to my 18's, I'll be double check'n it all again...

Unfortunately, I haven't had a chance to eval the difference the locker makes off road. But she DOES leave some very nice equal length digs when I NAIL IT in the gravel parking lot @ work...

I'm hoping to do some extensive testing up north this fall...

ESPECIALLY on ski jump hill & upper money talks...
