4.10s installed...? about speedometer

Hello,
I just got my 4.10s installed (they don't whine :) ) I'm in the breakin process right now so I haven't had a chance to really get down on them. But anyway, I'm attempting to recalibrate my speedo with a Superchips Microtuner until I can send the pcm off to pcmforless. Well, I've gotten to a question that ask for my tire height. It has low number of 24 and goes up to 28 +/- before it recycles back to the question of my tire height.
I have 275/40/17 all the way round on 17X9" rims (Stock SS rims).
Can someone tell what my height is?

Thanks,

Tim

Depends on what brand they are if you want it to be very specific.

Just go onto tirerack.com, plug in your size, choose the tire and then check out the data.

Thanks

The factory programs those as 25.65". As noted, it will vary by manufacturer and specific tire model.
