E vs. D rated trailer tires

We are moving back to WI after 4 years of living in Miami and I'm making my list of items to address since my unit is 5 years old. One of those is tires. I still have the stock 'Trailer King" D rated tires, and will be changing them out. What exactly is the rationale behind going to an 'E' rated tire on a camper? Obviously more load carrying capacity I understand, but does it ride harder then too? I certainly don't need more jarring transmitted to the chassis. I feel like if you need the load carrying capabilities of a higher rated tire you might also be overloading the chassis. Is it just higher quality of tire? Kind of like going to an 'F' when an 'E' will do the job more comfortably. Is it just peace of mind / bragging rights?

So to succinctly answer your question with the vague info you provided.

If your weight is under the rated capacity of the current tires, it's mostly peace of mind (because in as many bragging rights conversations I've witnessed about any vehicle, RV or motor toy, noone has EVER been like "Dude, I GOT E tires, not those lame lookin D tires).


No they won't cause ANY issues by upgrading. Just set the pressure right and they'll generally be tougher when abused than the lower rated (thinner less strong )tires.
