Tire presure for SRW with 19.5 G rated tires?
Getting conflicting advice on what TV tire pressures to run. Truck is a SRW F-350 with aftermarket Vision Hauler 19.5 x 7.5 wheels. Tires are Coopper Roadmaster 245/70-19.5 G rated at 4520 lbs. @ 110#...

I agree with BenK it would be possible to have a bead break if you were running way lower than recommended for your speed psi and made a sharp turn. It is how you dismount a tire for changing after all, lower the psi and apply lateral load.
None of those trucks in the CTI videos run those low pressures at high speed.
One could also speculate there are many vehicles running around with over inflated tires (if recommended psi is good MORE is better) that have less than ideal braking and cornering tire traction available when they need it.
Here in washboard gravel road, ice, snow, and mud country you soon learn not to blow every tire you own up to MAX psi or you are in the ditch...
I think if I blew my 19.5's up to 110 psi I would have a tread footprint about an inch long on the road. :)
