hay mate if you put 31s on your sierra for sand driving it will make it worse unless u fix the gearing issue it will have no power and struggle like sh!t.

I've got 2 or 3" suspension lift and hammered seams, no body lift.

2" BL- 31's no worries.

Suspension lift will not clear a bigger tyre unless your bumpstops are moved down.

A 2" suspension lift that clears 31's without rubbing will mean the springs are too stiff or the shocks are too long and acting as bumpstops.

so let your tyres down, you don't need lift or big tyres you need low tyre pressures. Larger tyres will mean your gearing is out and it wont have anywhere as much power as with smaller tyres with low pressures

In fact, for cars with limited horsepower (like everyone, really) wide tyres aren't helpful at all.

Watch a wide tyre on the sand - there's a little bow wave of sand being pushed in front of the tyre when the cars moving. The wider than bow wave is, the more power it takes to push it.

What you really need is a tall, narrow tyre. The same cm2 of footprint in a narrower tyre will take less power but the same floatation.

Ever wondered why Paris/Dakar cars run 7" wide tyres... with 400L of fuel and massive, massive dunes? It's becuase they are generally horsepower limited, if not by rules (although they often are) then by fuel range. Smaller tyres take much less power to push.

That's the ting. When you air down, the tyre gets longer, not wider, and that's why it's a a massive advantage.

Gearing, of course, is vital.

I was going to say this, plus borrowing your mates welder for bump stop extensions.

That said big tyres aren't the be all and end all of offroading.
