WOW. No wonder they look small.

I can't wait to get my new 33" mud terrains on there. That'll give me a 4" taller tire and should raise the hieght of my truck roughly 2".

I thought 245's measured around 30.5-31"?

So what do your tires measure, whether you have 245's, 265's, 285's, 305's, 315's, etc.? Do they measure on the ground what the manufacturer says?

How much air pressure are you running your 245's?

You can tell the difference between compessed diameter and uncompressed diameter by measuring the tire from the top of the tire to the center of the hub (uncompressed) and then from the center of the hub to the pavement (compressed). Then there's rolling radius......
