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)?
Thanks for that chart. Just printed it off to keep for reference.
FWIW, I run my tires during the winter (dedicated snows) at psi on door jam. Not worried about towing the sled trailer on weights. Summer tires and 5er, run at sidewall psi. Makes for a stiffer ride, but no problems.
