    I run 35in BFG All Terrains and I measured them today to find out that they are not really 35in tall. The front is 33in and the back is 33.5in. All my tires are fully inflated at about 35psi.

    I've heard that BFG runs a little small. So just curious what your tires say and what their actual height is.

    How wide are your rims? My BFGs were 34.7" tall with 32 PSI on a 15x8 when new. They were about an inch shorter when I swapped to a 15x10.

    I have 37X12.5 on a 15X8 and the most worn one which has about 3/8" tread is right at 36.5" tall. I have not measured a new one but I would venture with 19/32 tread it would be right at 37 or close to it. I also run 25# pressure.

    Loaded height of my 39.5" TSL's is 38.5" with 23 lbs of air. They're about 40% tread left.

    Circumference of the tire is 123.5", so my true diameter is 39.3"...and the amount the contact patch squishes is about 3/4".

    I've posted this picture before, but the 395/85R20 XMLs are 46 1/2" true height brand new mounted on 20x9 wheels. The 44 Boggers are 42 1/2" tall true height (with a little wear on them) mounted on 15x11 wheels at 16 psi.

    I don't know what the other manufacturers publish, but BFG posts the specs for each of their tires. They spell-out the rim size used to get the height measurement, AT FULL PRESSURE. My "E" load rated tires are measured at 80psi. For DD, everything will be less.:D
