Every other F150 comes with 4 ply XL rated tired including the ones rated to tow 14,000 lbs.
I can safely say a E load at 34 psi is a rougher ride than a C load at 34 psi.
Before I had a raptor (last 20 years) i off roaded my F350 powerstroke my off road air pressure on E load 315/75R16 tires is 30 psi front 25 psi rear light load 30 psi heavy load.
You can barely tell by looking they are deflated from 65-70 psi (ride is/was amazing though)
Once the snow was so deep and road so icy I aired down to 15 psi for about 25 miles. Sounds low, but seriously looking at the tire you would have thought it had 30 psi in it
Raptor off road with C load is in the low to mid 20 psi
34 psi on a load E on an F150 isn't really "aired down" when on the same truck a C load has a vehicle manufacturers recommended psi of 38 (max psi by tire manufacturer is 50 psi)

I'm not sure where you are getting your information from about F150's tires, I can't find anything to support your statement.
All I see is that they run 18" rims and are smaller tires. Not 315/70/17
And a regular cab F150 is what, 800-1000 lbs. lighter.
And towing capacity has only a little to do with load weight on the tires unless you're going to 14,000 lbs. on the tongue.
Your statement "I can safely say a E load at 34 psi is a rougher ride than a C load at 34 psi." is unrealistic.
Of course, a C rated tire is going to be softer than an E rated at the same psi.
Hey, you drive on tires you feel comfortable with, and I'll drive on tires I feel comfortable with.
That's why they make different tires.

The C class only became available in middle of 2017 so almost five years, still the same set???
Many Gen II owners have switched to E class because C's only go 30K-35K miles before they are garbage.
And you don't mind the extra roll when changing lanes quickly?

Same set. Truck only has 44K miles on it. 35K is typical for tires that I had on various Ford trucks over the past 45 years.
