Tires

[Ed67]

Tire question for 1/2 ton truck trailer pullers. Anyone here running Load range F tires instead of E?  
I currently have F rated tires/Toyo AT3s on my Tundra but dang are they a rough ride and wondering if it’s overkill. 
my current trailer is about 5300 empty.

F is over kill.  E is what i always use in my diesel pulling heavy and no issues.

Run BFG KO2 load range E on my F150, run 80psi when pulling my 24ft travel trailer.  When I get to camp I drop the tire pressure back down to 32psi.  Air back up to 80 when pulling trailer back.

E is fine, I pull 35 ft 5th wheel all over the west.

D or E should be fine. F is way to much. I have run D & E on 3/4 and 1 ton trucks.

The nice part about heavier tires is tougher sidewalls. That also is what causes worse eise though. 

My 1 ton right now has E rated and I down my 21' trailer at about 55psi. I street drive it at about 40psi.

I’m definitely switching from F to E

This makes no sense

The wheels that come on a half ton are not rated for the 3000+ pounds that a load range E tire can take.  They hold up better in the rocks but you don't need to run 80 psi

 Your wheel bearings and springs can't take 6000# either.  I run Es on both of my F150s but I have never inflated above 50 psi. 

I can't imagine how rough it would ride.
