the overall tire diameter on 32x11.50x15 BFG A/T's is 31.7"....it is REALLY hard to measure a tire diameter when it is installed on a vehicle...

here is where I got the info:

Plus..NO tire company is true to size. BFG runs a little smaller, as they always have. And I believe it's Interco that runs a little large as well. Some depends on rim width, tread wear, and tire inflation.

Thats not true there is some company that is off by like .1 inch's if that cause I got new tires last week and was looking at the real sizes.

TSL's run large as well. There is a pic on pirate showing bald TSL 33x12.50's vs. Cooper STT 33x12.50's

EDIT: Here is the pic.


I know the TSL's are not mounted but you get the idea.
