Should I get the big wide single tires or standard double tires on my truck?

I've been driving 18's ALL my life but I keep seeing these semi's with the BIG single tires all over the vehicle so I FINALLY have to ask.

It's been bothering me a long time and I keep forgetting but now we're here -

What's the difference?
What's the cost?
What's the benefit ? If any.
What's the reason?

AND ANY OTHER QUESTIONS YOU CAN ANSWER and think of regarding these tires. I'm going to be needing new tires soon so I'd like some feedback about them if I'm going to make the switch. Thanks.
