The front tires on my 1994 Civic EX coupe are wearing unevenly. The
inside edge (2-3") of both tires has worn down almost to the belt.
I'll be getting new tires and a 4-wheel alignment in a couple of days.
However, I'd like to be a bit more informed about what might be causing
the problem, and be prepared if the alignment guy says I need major
suspension work.

So, any ideas what might be causing the problem? And, if I can't get
the alignment done at the place I buy the tires, should i get the
alignment or the new tires first?

details: tires have been properly inflated for the most part, no work
done to the front end recently (save for new front brakes), no hitting
of curbs or major potholes recently, first time this car is having an
alignment done.
