Actual Measurements of 39.5 Irok Radial

I posted a thread like this on the jk-forum with no luck so I figured I would try here. I would like to know what they measure out to once they have the weight of the jeep on them.
Thanks in advance

Sorry for the slow response, I have 39.5 X 13.5 R 16 super swamper Irok tires. With the 16 inch rims that are only 8 inches wide, and only 15 psi in the tires they measure 38.5 inches tall.

I have a Tj, that is roughly 5,000 pounds the way I measured it. Fully loaded with tools, spare parts, and spare tire. Also has one ton axles.


My ride- 2001 power wheel, 11" plastic tires, upgraded battery, boat sides, custom bumpers, tow hooks, new paint.

There are so many variables, that it's hard to pre plan how tall yours will run. I was able to borrow a set of boggers from a friend to see if I could clear 39.5s. They are the perfect size tire for my rig. View attachment 88769
