Just got the new shoes for the truck installed today - Cooper Discoverer AT3. Quite the upgrade from the junk Hankook Dynapro HT's that were on there. However, have a question on determining the best inflation pressure, especially when towing our trailer.
The truck is a 2011 F150 Ecoboost with the Max Tow package and 1820 lbs of payload. It specifies a 114T tire @ 35 PSI.
We wow a 9900 lb GVWR travel trailer with probably 1100-1200 lbs of tongue weight (875 "from the factory") so we're near the max when we tow.
The Coopers are Load range 116T so I gained a little more capacity.
With the previous Hankooks I'd air up to 40 PSI all around as we found the ride too bouncy at 35 PSI. They had a max pressure of 51 PSI.
The Coopers' max is 44 PSI. So I'm wondering if it would be good to go to 40 or shoot straight to 44 PSI?
Thoughts?
