    I have to say these are very helpful. I have heard of a few but not all of them. Which ones do you usually use?

    • Hi AJ,

      If you mean the abbreviations, I use a few. There are a lot of the ones we hear all the time such as VIN (vehicle identification number), AWD-all wheel drive, A/C-air conditioning, just to name a few.

      I’ll come up with a basic list and put them on the site.

    This is so helpful it’s not funny. I need to send my wife to this site right now! She’s ALWAYS asking me what’s wrong with her car, how to change her tire, etc. I think this will help her understand everything tremendously. I just checked out your link and will begin reading those abbreviations as well. Thanks for all of this!

    PS: Do you have any articles for changing tires?
