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#
Towing Toy Hauler in sig, +/-14k# loaded, approx. 2900lb pin.
Truck is only used for towing.
When I bought the wheel/tire combo, I thought they told me to run 80-85. Others said run 100-110. I've been compromising and running 100 rear, 90 front.
Checked tire temps last trip on an 80 degree sunny day after driving 100 highway miles @ 60-65mph. Fronts were 106F and rears were 116F. All 6 trailer tires, E rated Maxxis ST at 80#, were in the mid-upper 120's. Seems good to me but just seeing what others might have to add.
