I paid about USD$95 each for four tyres, and about USD$55 for alignment, just a few weeks back.
But looking at what US-ian posters are paying, I think I got a pretty good deal. They weren't even the cheapest tyres.
I have previously taken a car on the ferry across Bass Strait to have major work done in Tasmania (60% the price of Melbourne).
Disturbia my friend, I think we should be looking at outsourcing our car repairs to M'sia next time! :-D
