It doesn't matter. It's the wheels (actually the hubs) that are getting
aligned, not the tires. IMHO, sooner is better, since a good alignment
will help you enjoy the remaining miles on your present tires. If you're
interested in improving your Miata's performance, see my page below for
suggestions.
