There is a saying: "If you can't afford to do it right, you can't afford to do it twice."
The older I get, the more I wish I had listened to that...
If you really are that desperate, I would recommend looking at used tires instead. Go to the shady parts of town and find the "licensed" (note scare quotes) tire places. When you feel you might get robbed driving through the neighborhood, you're at the right place.* Bring cash, but not much. Like $80 (total, not per tire)**
Tell them you are looking for some used tires (tell them the truth, make up a story about wanting to do burnouts, traveling through and hit a nail, whatever) and see what they have.
Next thing you know, you'll be rolling on some high-mile, but still legal, tread! Way safer than recaps, and probably cheaper.
Then start putting your pennies aside for real tires.
* Getting used tires installed is not legal in all areas, which is why you have to find the shady tire stop. If your state allows this, then just walk in like you own the place and order up the cheapest pull-offs they have!
** Note: I have done exactly this when dirt broke in college. That number is what I paid for 4 BFGoodrich Radial All-Terrain tires with
just barely enough tread to be legal (and get me through the semester).
Edit: also, might look at what junkyards have. Some junkyards will sell wheel/tire combos dirt cheap. Any 1985(ish) up Ford truck, 1990s up Dodge truck, and basically any year Chevy truck tire/rim will bolt on. Unless you have a 2011+ Duramax, when they changed the bolt pattern. But if you have a 2011+ and can't afford tires, I am not sure I can help you
