Truck tire pressure

[Scottcleaver]

Getting ready to load up be gone 4 months. I am thinking I may want to add some air to the dually tires. I have towed our 2013 36RL about 500 miles so far and everything seems fine but I wonder about underinflation. Drive tires are at 52psi and the 2 steer tires are at 60psi. The Michelin tires say max at 80 and I know how heavy these RW are at the pin. With the 5th wheel hitch in the bed and a tool box/ fuel tank combo Im sure that i have another 1000lbs or close. Im thinking the 50psi rears are quite low and maybe even the fronts that are currently sixtymay be low as well. Pic attached shows PSI and weight limits.
Thanks Scott

What does the label on the door or door pillar say for normal pressure, that sounds awfully low pressure to HD Truck, plus it would be a really big help if we knew what your TV is.
My GM list 70 front and 65 rears, but since we travel heavy I'm running 70 in all 6 and 125 in all 4 RW tires.

My F350 dually door pillar says

Front 75PSI
Rear 65 PSI
Spare 75PSI

I would say 65 MIN on the front , the truck empty is going to be around 4700 on the front tires. as for the rear I think 60 would be the min I would run. my truck scaled almost 8K on the rear axle but I don't know what your driving . I like to run about 5-8 psi more then the min for the weight .I know it reduces the size of the contact patch on the ground and its less likely to slide on a wet road.

I did just as M&A, 70 on all 6 of the truck & 120-125 on the 17.5" RW tires. When I had the 16" GY g rated on the RW I ran them at 110.

80 on the front and 65 on the rear for my Ram dually, as specified on the door frame. If you drive around much without the trailer, you may want to reduce the front tire pressure. My 17.5's are rated at 125, but run them at 115 which is well withing the weight carrying capacity at that PSI. It gives the RW a much more comfortable ride if you don't need the capacity. SmartWeigh, an Escapees weigh program, will give you a better chance at getting the tire pressures correct.

2017 F350 DRW. I keep mine at the max, 80 psi, tires run cooler, & last longer. I usually get at least 100,000 + out of Michlen tires.

2017 F350 dually, we run 70 front 65 rear cold, tires are wearing even. 38K on the truck, only 2000 of them not pulling the Redwood.

When towing heavy loads like your 36RL, it's important to ensure your dually tires are properly inflated. Based on the shared experiences, it's generally recommended to inflate your tires closer to the maximum pressure indicated by the tire manufacturer or your vehicle's specifications, especially when carrying additional weight.

For a heavy load, tire pressures around 70-80psi are often suggested. This helps in maintaining tire integrity, ensuring safety, and improving handling. However, always consult your vehicle's manual or door label for the most accurate guidance.

Remember, correct tire pressure is crucial for safe and efficient towing. Safe travels!
