Just wondering how well will muddies for the tyre size 235/75R/15 go in the sand for my 1.3L sierra

No problem. Just let them down

understanding are Smoother patterns are better in sand

Sure, but pressure is a huger factor than tread pattern.

I drive a lot of sand and I've never had a problem with mud tyres, even on bigger cars.

I normally run 5-6 psi in Suzukis and 10-12 in bigger cars, though I have had to go lower.

I lived on a sand island for two years and had silver stone mt117ex tyres. No formed roads, just sand so I only ran 3-5psi at all times and never had a issue.

They might be slightly better than muddies for initially taken off where most people do get stuck but in general muddies are better. Once you have momentum you will be able to climb bigger dunes and go further with muddies as they will dig in better and will grip with the side lugs when snaking through deep sand. So you might need to think about where you stop a little more but that's it.

The most important thing with sand is pressures. I honestly think I can go further in 2wd with the right pressures over 4wd at road pressure.

I feel (no testing or evidence) that the main negative for muddies in the sand is they dig you down to your axles quicker. If you have a controlled right foot, you can almost completely negate this.

I thought the only possibly arguable negative for mud tyres is that (compared to HTs) they almost always have a far stiffer sidewall and don't bag out as easily so require lower pressures in comparison. Hardly an issue really, but that is about the only negative I can think of.

The whole 'digging' thing is a myth, I believe.

If you struggle on sand in a sierra with any tyre then your pressure is totally wrong (needs 10psi or less) or yoyr sand driving style is totally wrong. If you get seriously bogged then give you keys to your missus, she can likely drive better.
Unless boggers you can dig to china with them in the sand

It is true that they dig more, but it will only really affect you at very low speeds and initial take off. For climbing, cresting and driving dunes it wont be an issue. In fact the more aggressive muds will be better as you can use the sidewall of the tyre for extra traction when you feel you are starting to lose momentum. As long as you think about where you park and keep momentum up which are both good habits to get into, you will be fine.
