Tires: tire wear, sequence of events, alignment

Question
i have a slight concern about my alignment i have takin my car to 4 different shops to have it aligned the first shop fixed everything and all the others said it is dead on and nothing needs to be changed even after repeat visits       the tires that i have on my car are wanli i didn't like them but i got them for 20 a piece almost brand new   thing is they were on a car for about 4 months they went flat and dirt pushed the tire up and had the tire pinched against the inside of the rim    would that cause and problems ? i'm sure it probably did         my main question is the inside of one of my tires right on the edge is worn completely bald  "the front left" could that be from the car they came off of having a bad alignment or possibly the bands in the tires being bad i know they arent the best when i put different tires on my car doesnt jerk around while driving  any ideas or suggestions ?    i don't want to spend money on new tires and wear them out    i would like to find the problem and fix it before i make the investment           thanks for your time and opinion

Answer
Brad,

Relative to the dirt.  If the dirt was completely cleaned out and the rim was checked for out of round - and it wasn't - then the only problem ight be whatever situation caused the dirt in the first place - and it's possible the tire was damaged during that sequence of events.

The tire wear you desribed is probably from before you did the first alignment - and once you get alignment wear, you've got it and can get rid of it.  After all, you can't put rubber back onto a tire.

If the alignment of the vehicle is OK, then new tires should probably wear OK.
