Recommended cold PSI is 60 front & 65 rear. They are Michelin 275/65/20 load range E on a 2017 F250 Power Stroke. Should I increase the pressure when towing my 39' toy hauler (Triton by Voltage)?
I’ve owned many trucks and autos over the last several decades.. I’ve never seen 100K on any set of tires no matter what brand... I am sorry but I don’t buy into 100K on tire mileage..
And if you are towing a fifth wheel I’d bet getting 50K would be about the maximum you’d ever be able to see, and have any safe level of tread depth left..
