Overall height=parking garage woes?

[navigator32v]

I finally ordered my new wheels and tires!!! My wife had concerns regarding parking garages downtown Seattle--priamarily the one she uses.
I'm having some 315/75r16 Nitto Dune Grapplers wrapped around some 16x8 black Helo Maxx6's, it should look good with the birch white.

The Hummer website states 74.5 inches tall. I added 1.5 inches for the increase in tire height from 32's to 35's. 76.0 inches, anyone ever actually measure?

My Navigator was 76.69 inches tall with the roofrack so I think we'll be in the clear. I just thought some of you may be interested as I plan on measuring overall with the new tires and posting pics...anyone else?
