I have had 350's loaded all the time with D tires and have never had a problem. Currently have a boss 9'2" vee and a 2 yard sander with 2 tons of salt loaded I plow with ever storm. I like you went with D for more choices. You will be more than fine with D.

A general rule of thumb is, if you are going to load the truck the way it was intended, keep with the manufacturer's specs. Meaning, stay with the E-rated tire.
If you're going to use it as a daily driver, and hardly ever carry a load, a D will do OK.
But I wouldn't tow or haul with them.
We've had many discussions (disagreements?) on this very subject, and there are many different opinions on the subject.
BUT - some tire shops will refuse to install D-rated tires on a truck that calls for E-rated from the factory. I wonder why?

When you are changing the size of the tire D or E really has nothing to do with it. Go by the actual load rating in lbs. Typically because you are going to a bigger tire, you could step down to a D ply because the bigger tire will take more weight anyway. Compare your stock tire to the tire you are thinking of buying and go from there!

There IS a difference. Otherwise, why can I buy one 265/75R16 tire in an E-rating and another one in a D-rating, same brand, with the exact same size, tread design, etc?
Because there's a difference. It's called sidewall strength.

Krewat......you're not reading my post as I intended, you CAN by a 265/75r16 D and E ply, for different vehicles and different applications, this is not what I am talking about!
A bigger tire will hold more weight than a smaller tire, of the same load range, that's all I was saying. It's a fact, not an opinion. My advice was that if you go up in size, you could step down in load range because the bigger tire can hold more weight.
See below as an example, cited from BFGoodrich's website.
These are the BFG AT KO's exact specs:
LT265/70R17/E 121R RWL 55086 7 - 8.5 10.7 on 8 31.8 16 654 3195lbs@80psi
LT285/70R17/D 121R RWL 24475 7.5 - 9 11.5 on 8.5 32.8 16 634 3195lbs@65psi
In this case, the OP can step down to a D load range and not lose anything in load carrying capacity!

That should be REAL fun when towing or heavily loaded.

Thats the exact tire I use and was referring too - BFG AT KO's never had a failure.

Truck is rated @11,100gvwr + - 2 tons salt puts me on the scale at + -11,500.
So over weight for officials? yes. Over weight for me or a ford? no.
Not as bad as some Chevy's I see

Me too, never had a problem, even when towing 25000 lbs, because matching the load capacity is the most important issue.
An inch more sidewall is likely not going to be detectable when referring to sidwall flex for most people, even when towing heavily. But nevermind, I guess I don't know anything and should give up after 6 years in the tire business!

I agee with Weldman! I've used Cooper and BFG D & E rated tires for years plowing and hauling heavy loads. Never had a problem with sidewall deflection. But then I'm not one of these guy's that's hauling a 40 ft goose-neck doing 85 mph and wipping in and out of traffic either.
