like he said ^
figure out what you want from tires, then get them. ordering them on line isn't that big of a deal if you know exactly what you want. From there, find a place like Firestone that will do lifetime alignments. The thing I personally don't like about them is that their machine puts everything to center. Lines it all up to what the stock specs are and calls it done. At least most of the time it is like that. I personally want to tweak with it a little bit here and there. If that's what you want to do, then find a place that will put the alignment where you want it, that just takes calling around.
