Class C vs E in soft sand

[VIZA IVXX]

Which would be better suited for climbing deep soft sand dunes on a stock 2016 4runner between:

255/75/17 class C
Or 265/70/17 class E

I'm thinking the 255 is skinnier but can allow more stretch and hence wider footprint due to the softer sidewall, which will also increase puncture risk.

The 265 is wider but stiffer and am wondering if it can bulge enough at low psi and float over the sand.

Not concerned about anything else like road noise, comfort, wearing, etc.

I'd simply like to know which would be best for driving on deep soft sand between the 255 class C and 265 class E on stock 2016 4runner2016 4runner.

Thanks!

Sizewise, there is so little difference, I don't think it would matter. Comparison
But for soft sand, think: rounded shoulder tires - so they don't dig in and bury themselves. The more square shouldered - the worse the sand performance will be. If you're not interested in weight carrying or sidewall damage, the "C" rating would be more flexible & comfortable riding. Airing down the tires actually helps to protect the sidewalls from damage, contrary to what most folks think. Example: what's easier to pop? a half filled balloon or a fully inflated one? Also, stiffer sidewalls (E rating) usually don't perform as well when aired down. It's your choice, though

Thanks.

I'm leaning towards the maxxis bighorn 762. It comes in load range D and has a pretty good reputation in sand.

I am concerned with punctures because the rocks here can be sharp and hidden under the sand and mud. Altho I've never busted a street tire.

However with muddies I will get crazier than with street tires so I do want the extra projection.

Any experience with the 762s?

Thanks .

Sorry I meant to say the 762s come in load range D size 265/70r17. I'm thinking that would offer a wider footprint, taller tire, and range D protection and flexibility.

265/70-R17 are pretty similar to the "old style" 31/10.5-R15 tires.

In soft sand, you'll want to run them near 12psi. Without doing any sharp turns or fast speeds. This size of tire is hardly a sand dune master (I've used 31s in the sand a lot). C rated tires' sidewalls will flex better giving more sidewall blulge at lower pressures. A little better flotation.
A "D" should work virtually as well. A "E" is pretty stiff for sand.

Thanks output. I appreciate the input lol.

With your opinion I feel more confident about choosing a range D.

I feel it will offer flexibility for sand and 8 ply puncture resistance.

Maxxis bighorns are confusing and I originally said 762 but meant 764. I'm leaning towards the 764 based on your experience in the sand as well as some reviews from Australia where the terrain is similar to where I will be offroading.

Thanks!
