Questions I Had When I Saw These Big Tires

Okay, I took a pic of these tires because 'those are some tires'! I just had so may questions when I saw them.

1) Who get's to put these on?

2) What kind of rims do these suckers have?

3) What happens if there's a flat?

4) Can you air them up at the gas station?

5) Does my little tire gauge work on these?

6) Where do you put the spare?

Okay, I'm done! LOL
