tire size wont matter and lowering the tire pressure wont help much
if you wanna go on the beach sand you should get some mud tires or all terrains
also when your stuck you should always use 4lo so you can get more torque and traction in the tires 4hi is just going to make holes and be harder to get out .

Bad advice. Makes me wonder if you've ever driven on sand before.... Bass ackwards!
4LO doesn't increase traction, that is all in the tires, but it certainly increases torque which if used incorrectly will cause more problems than 4HI. The only point at which I would recommend using 4LO is if you are bogging down too much in 4HI. Even then, you must be ginger with the throttle. Once you spin, it'll just dig a hole.
With sand, you want as much surface area as possible to support the truck and not sink in. Regardless of the tire, lowering the tire pressure will increase the surface area, thereby lowering the contact pressure & keep the truck up on top of the sand better. True, stock tires don't have much of a contact patch to begin with, but every bit helps.

Larger / wider tires will help, yes. Larger tires help by lessening the contact angle at the front of the contact patch and increasing the footprint. Wider tires help by increasing the footprint. All around, x was way off.

I generally tack about 50% of my air when going out on the beach unless it is really soft and I have a heavy load, then I take a little more out. I am running 30x9.5x15 BFG AT's. If you look at my pics you will see it on the beach.
