This has probably been asked before but because we are leaving in the AM for the summer I need quick advise from the folks on here. We have a 2013 Ford F350 SRW 6.7L Diesel and a new to us 2016 Key...
Personally I don't see that trailer tires take any more of a beating than the tow vehicle tires. I run my rear duallie tires down around 65 psi. That's plenty of capacity for the load, about 7,000 lbs, and it doesn't beat us up as bad. Fronts run around 70 psi due to the Cummins up there. I usually run the trailer tires based on load plus 5 psi.
