All:

My car needs 4 new tires and I know I can save a bunch of dough if I buy
new tires online and replace them myself, however, I've never done this
before and I'm curious if others have and if so, if they can either:

a) recommend against doing it myself; or
b) tell me that it is a good idea and suggest where I might learn more on
how to do it.

I've done some preliminary research on the subject and I haven't found the
definitive set of instructions yet.

Thanks for your advice in advance.

Steve
