So considering the weight of these trucks are d series tires good enough? I see quite a good selection of off road tires in the 33" to 35" range that are affordable. The selection drops off a bit with the E series and they are considerably more expensive. I notice the tires that are on it now are D series but the PO never hauled a thing. Id like to drag the fifth wheel out on the weekends or the boat to the bay without second guessing if I am going to make it or not... D or E? And no I haven't researched this so I might be getting ahead of myself with this post... Thoughts?

 

What's is the pin weight of the rig you are looking to pull? The tires (IMO, others have different views) are, I believe, the foremost limiting factor on how much weight you can put on the rig.

 

If the D tire rating are within your range of use then go ahead and use them. Just have to remember that you can't go above them.

 

Go with the E rated tires only

I have run D and E rated tires...

No reason to run E for 99.9% of the guys out there. Buy quality tires and you wont have issues...









All D-rated tires...

 

How would the laws for this work in your state ?
D rated tires must have been well overloaded ?

I have seen D rated tires that are within 20lbs rating of similar E rated tires.

As far as laws, if you are not getting paid to tow it ( in Oregon) no one cares. I believe there are laws on the books stating you cannot go over maximum specified weight limit of a tire but I have never seen a set of jump scales deployed on a pickup that did not have a DOT number on the side.

 

Here in Ontario Canada.. Truck and trailer need to be inspected yearly if GVCW is over 10,000 lbs..
With 8000lbs excursion you get to 10,000 quickly..

I was just on tire racks website

285/75/16 LTX MS E 3195lbs
285/75/16 LTX MS/2 D 3195lbs

Load range is not as straight forward as " E means more"

An if you need to get REAL heavy, just slow down and keep an eye on tire temps. An IR gun works for this but a calibrated Palm works just as well.... " ouch that's hot, I should let it cool and when ready proceed at a more resonable pace or perhaps wait until night fall to cross the mojavie desert with this very large load on my light duty pickup".

 

The E rated tire "should" have a stiffer sidewall and therefore you should have less squirm from your truck under load. At least that is how I understand it to be

 

Sidewall stiffness is no way related to load rating. Case in point that Yokohama Geolandar A/Ts in a 10 ply as well as the Michelin LTX AS tires are both far more squirmy than any 8 ply Cooper or Dick Cepek tire I've ever run; they feel flat even at 80 psi with no load versus steady and stable at 65 with the 8 ply tires fully loaded.

 

These are 3850 rated... I've been well over 28k gvw several times, driving 75-80mph for 12+ hours straight...

 

Dose rims !

The 49" IROK tires I used to run were rated at 3600 lb. at 25 PSI.

 

And the tire weighed 1600lbs so you had plenty of room left for a six pack and a pepperoni stick.

J/k of course, but seriously, how much does a 49" Irok weigh?
