Tire Load Rating question

The stock tire on my Super Duty is a 265/75/16 Load range E. Is it ok to use a 285/75/16 Load Range D or does it have to be an E?

Depends on how much weight you're going to be putting on them. I can tell you from experience, once you've had 10 ply tires (load range E) and you go to 8 ply (load range D), you'll notice a difference in handling

Here's a pdf load/inflation table. You shouldn't have any problems. Just make sure you have adequate inflation and tweak until it handles the way you want it too.

If you never carry anything yes they will do. If you ever have a blowout and you cause a wreck you may be in trouble.

Well Bigd it looks like your truck has tires other than the recommended fitment by the manufacturer so you must be a gambler too!

WHOA, WHOA THERE BIG FELLA... Hate to be the bearer of bad news but this is for your own good...

This is NOT a function of what will work or what feels good or what ever.. If your truck says Load Range E, and you put on LESS of a load range lighter tyre and a blowout causes an accident...
YOU COULD BE OUT OF INSURANCE, like zero, zed, nada, nuttin, NO INSURANCE!!!

You are fine until the baddie happens. But almost everywhere in the world the Insurance laws are the same, and you could be denied coverage in an accident if they say the tyre blow out was the contributing factor and you were running a lower load rating than it says on the inside of your door panel..

Hate to rain on the Parade, but I am the Director of a Company in the Business of rules and insurance, and you can bet this is true. Greater size or greater load rating, no problem, but you CANNOT GO LESS or you risk being denied Insurance JUST WHEN YOU NEED IT MOST.. OK with this??

Trust me, it is true. That is why the sticker on the inside of your door, MEET OR EXCEED is the ruling on this one...

Cheers from the lone Ranger..

Ok for one Load range E is only rated on avg 300 pounds more then Load Range D.

Another thing, I bet you don't even come close to load range D when your truck is fully loaded.

Also if you really want to keep the load range E tires. You can get some tires in 285x75R16 that are Load range E.

Nitto Terra Grapplers are one tire that comes to mind that is offered in 285x75R16 Load range E.

Also in the USA the States write up there own insurance regulations. So it can very from state to state. I understand what your saying Lone Ranger, but the possibility of finding during the investigation that a tire blow out was the cause is unlikely. Unless a witness or the driver states the tire blew out.
