On bigger rims though.
See, I'm thinkin' basically unless tires are labeled "LT" they won't be 8 ply equivs.
6ply equiv LT tires are the MINIMUM anyone will run out west on even gravel roads. The ranchers out there usually run 8ply equivalents. I could be wrong but basically 4 ply equivalents are pass. veh tires at a max of about 50psi, 6 ply equiv. LT tires might be max press. 60psi and 8 ply equivalent LT tires will be around 80psi.
BFG A/T tires are usually 6ply equivalent (3 plys that count as 6)
On my 1996 Tahoe, my old Coopers, two sets, forgot the model name both All Terrain tires had a make press. of 80psi.
You could run all day at 85mph and be assured you could also drive on railroad ballast for hours and never get a flat.
I find it confounding that no Light Truck rated tire is spec'd out for these nearly 5k lb SUVs.
Disturbing.
