Are load D really softer than E

I don't remember my Suburban 3/4 ton being "harsh" with the load E tires- is there really a noticeable difference?

We put the e load tires on from the recall, EX used to ride like a Cadillac with the d load, now it rides like a covered wagon. When these wear out i'm going back to d load tires since we don't tow with it anyway.

If ya drive any gravel roads and pack a load of any kind like simply camping gear than yous the type E. I got the only Tire machine around and fix a lot of D rated tires at 25 bucks a pop. And man do they pop easy. On the other hand if ya never leave the black top than go with the lighter tires. Also the E will last longer. Up to a year depending on how ya drive. Run em at 32 PSI on the hiway if yer running light. They will feel about the same as the D. Never excede 40 PSI on any light truck D or E. Yes I know a hard tire will give better fuel mileage but will not handle as well or last as long.

Best thing to do is buy Load E so you have them if you need them. I run 40 psi (not towing) in my Ex with Load E and they ride great. D's do have fewer ply's in the sidewall so they would ride better but not that noticable to running E's at a lower PSI.

VERY POOR ADVICE!!!

I'll just assume that you worded it incorrectly. Certainly that's the case, right?

Ditto! NEVER go lower than the PSI pressures listed in the door jamb ... those are the minimum pressures. Conversely, do not exceed the maximum PSI rating listed on the tire's sidewall. I keep 65 PSI at all four corners with E-rated tires, and am considering pumping them up to 75 or 80. The truck handles much better with the higher pressures.

Being aware of heat in tire is huge!! I would suggest to shoot them with the laser temp gun after driving several miles at the 40 psi and compare temps to when you run them at 65-80 psi. I would never go less than 40 psi, haven't seen a difference in temps at 40 psi vs 65 psi. Now towing is another story I crank them right up to 80 when towing!! Like I said earlier though heat will destroy a tire and underinflation will tear up a tire and can really wear the outside edges of a tire out in a hurry. My truck handles the same at 40 as it does at 60psi, at 80 it definitly is different though. At 80 psi mine wanders around a lot, which I took care of a lot of that with the dual steering stabilizers up front.
