E Load Rated Tire Pressure

E Load Rated Tire Pressure
My truck is due to arrive this week. I have already made a deal with dealer to replace the stock wrangler sr-a tires with goodyear duratracs in the same size 275-65R18. I know the max tire pressure is 80 lbs in the duratracs but at what pressure should I be running these tires at. I think it is higher than the door sticker for the sr-a's. I was thinking about 58-60 lbs. Your thoughts?

The duratracs only offered in a E rated tire in that size. Same as BFGoodrich At's. I have run the BFG At's on previous half ton chevys with great success. I opted for the duratracs for the more aggressive tire look.

I've looked into this as well but decided against the 10 ply rating tires. You will need to run close to 50 psi for the 10 ply tires to stay safely beaded due to their very stiff carcass. The truck is optimal around 40 psi with 6 plys so I passed.
My neighbor got the 10 plys from the factory and had to take them off due to the harsh ride.

As for the harsh ride. I never drove my truck with the stock "car rated" tires so I don't know.

I swapped out my 265/60R18 michellins for some E rated 275/70R18 terra grapplers and didnt find that the ride was worse (as I expected).
I dont know what the tire pressure is though.

Bye F150, hello F250
Depends what you are hauling/pulling. If you need the maximum load for the tires, then you need to run the max pressure. You will NOT feel any difference in the ride quality- on a 6000 lb truck, sonene can tell me their *** can feel if a tire is 80 PSI vs 60? Doubt it.
I have been running my P rated at 44 PSI for 2+ yaers now- no extra wear, no rough ride, and I may be getting a little better MPGs than the same truck running 32 PSI.
The dott sticker is published based on the OEM tires- P rated, I assume. Its in valid with E, LT or any other tire not OEM'ed for that model.
