I stopped and helped a lady that had a flat, I could see that the spare was already on and flat so I didnt pay a whole lot of attention until I talked to her. So I asked her if she had a jack so we could take her tire off and run down to the store which was about a mile away and plug it(I always carry plugs, never thought of how to air up the tire afterwards

) ahhaha. So she tells me her jack is already under the car so I bend over and look, a guy had already stopped to "help" her and jacked the car up by the rocker panel

and the jack went through the rocker and was stuck quite good in it. took almopst an hour and a half to get the jack out of the body of the car, jacked it up, and took her tire down and fixed it for her. Dont guess the guy that stopped to help had any idea of where to jack a car up at

never seen a spare put on backwards like that.
My favorite donut spare tire trick is when people put the little spare on a drive wheel, drive around like that all week until the weekend before getting a new full size tire put on, and then wonder why their transmission or differential sounds funny forever after that.
there is a dodge pickup in town here gotta take a pic of it if I see it again, he has tiny tires in the front, looks like a 235 75 15 maybe, and then looks about the same size as my trucks tires which are 265 75 16. I guess it would be okay if he re geared the whole thing, but wow I would hate to put that in 4wd and run it 30 minutes
