I do not know the actual figure, but can say they would obviously cover an 80 that is fully loaded and allow for a safety factor. As an aside, they look good, they have an offset that allows for safety in fitment and the way the suspension/steering loads are not compromised.

I do recall the Toyota 80 rims were designed to hit a 4" kerb and not sustain any damage at 40 MPH, I run mine at max weight most of the time, (I have the weighbridge tickets somewhere) not had an issue yet on or off road, and I have done some s*** for sure!
