That one's easy-pull the outsider off the other side,pull both flats and throw 'em on the bed,install the one from the other side,and you're on your way.

I don't even have a spare for either of my duallies,so it's not an issue.

Make SURE your lug wrench fits all your lugs,and your jack and wheel tools work with that truck. I've found:
One time where I learned I had one lug nut that's a different socket size,and the lug wrench doesn't have that size.

Another time where all the tools were stored where they were supposed to be,but they fit a different make and size,and nothing would work properly on my truck. I lucked out and got the scissors jack to hold long enough to get the wheel changed before it buckled,and got the lugs loose with a 3/8 ratchet and socket from my tool box and a piece of galvanized pipe I found about a mile back from where the tire blew out. (I drove really gently back to town,stopping often to be sure none of the nuts was coming loose.)

Don't think that just having new tires will prevent flats! There's a reason most of the ranchers out here have loaded spare carriers on both sides of their trucks,and another spare either lying in the bed or cinched against the headache rack.
I'm also going to install on board air on my one tons,as soon as I find the rest of the A/C compressor brackets I need. I did it on my BroncWorth,and it's been really handy!
