Question E or C rated Duratrac.



My JK is scheduled to ship next week!!! I was all set to order Duratracs then I stumbled upon E vs C rated debates. Why is deciding on tires so difficult

I ran into an acquaintance today that is a tow truck driver/full-time "giver", so I asked his opinion. He suggested if I was going with C rated to double check the vehicle weight + tow rating is less than the tire rating which will ensure my tires are MTO (Ministry of Transportation) compliant. His conclusion was to go E rated, chalk test for PSI and go have fun. This coincides with my logic as well. A tougher tire = less chance of punctures, air down for even wear, would likely last longer and if it's noisier than the C turn up the radio

From my research I've been able to make no conclusions. Either it's perfectly fine to have E rated tire on a JK or it's the worst decision in the world. I need some help.

My JK will be my camping expedition vehicle and not a DD BTW.
Thank you

Duratrac has a reputation of having a weak sidewall...great for the mall no so much on a trail.

yes, I have read that about the Duratrac which is why I'm swaying more towards the E rated version. The duratrac is by far the most recommended AT for winter performance which is why I've decided on them it's only the E or C decision that's holding me back ATM.

The Gross Vehicle Weight Rating is the maximum the vehicle should weigh, including the tongue weight of a trailer. The load capacity of the four tires must meet or exceed this.

Each vehicle axle has a Gross Axle Weight Rating that shouldn't be exceeded, including the weight of a trailer tongue, which impacts the rear axle weight. The load capacity of the two tires on that axle must exceed that.

Each Duratrac LT265/70R17 C range tire is rated for 2470 pounds max load at maximum inflation pressure (50 psi). How does a pair of them compare to your GAWRs? How do four of them compare to your GVWR?

The E range max capacity at max inflation (80 psi) is 3195 lbs. I doubt weight capacity is an issue with your Jeep.

The E range are 50 pounds each, where the C's are 44 pounds each, so the Es increase unsprung weight more. The added weight may mean they have stronger, stiffer sidewalls--better for protection but a rougher ride, even at the same inflation pressure.

The E range are blackwall, where the C are white outlined, prone to get ugly with rock rash.

For an expedition vehicle that's not a DD, I'd opt for E. I've also seen the recommendation DuraTracs shouldn't be aired much below 20 psi. Hope this helps.

I asked the same question months ago and went with the c rated.

I run E rated on my 3/4 ton PU truck.

If you searched the forum you already seen this but thought I would add it to be sure. My research led me to believe side wall problems are only occurring in rock climbing situations. I am East of the Miss and have no intentions of rock climbing. I was more interested in ride quality and traction in snow/ice/rain and sand.

Two cents,

Lt Dan

Load range C or E

If you're wheeling in an environment with few rocks, sandy, muddy terrain, C load will be great.
I chose the E load DTs for the extremely rocky terrain here in Utah. They're outstanding.
I run them at 28-30 psi on the road, and they're as good as a C rated tire. 35 and above will rattle your dental work.
Don't let anybody BS u that Duratrac is only good in the snow. It's a great all around tire.

Thanks for the replies, very helpful. I live right on the Canadian Shield so I'm thinking E rated. Since my dealer quoted me $300 below anyone else, if I don't like them I could easily sell them and not take much of a hit to replace with C. This picture is a perfect example of type of terrain in my area.

More research has revealed that when Goodyear revamped the E rated Duratrac & the sidewall lettering changed from white to black, they went from 3 ply sidewall to 2 ply which is not what I wanted to hear.

Yes I was going to say that SOME of the E rated versions I have seen with 3-ply sidewalls, but it also seems to depend on exact sizing.

Contacted Goodyear asked if the 285/75/16 duratracs were 2 or 3 ply sidewall was told they are 3 ply.

I have D rated 287/70/17 Duratracs and they are wearing great and evenly. Even with D rated I have to air down quite a but. If your choosing between C and E, go with E. When aired properly they are not harsh at all.
