The tire is fairly old and the tread is pretty worn but there seems to be enough tread for a few more months. My real concern is that the tire appears to go concave toward the middle of the tire. Is this a sign of internal seperation or something else?

If its only going to last for a few more months, it's time for a new tire. Sounds like you could have a bad belt in the tire. The steel belt inside of the tire, underneath the tread is separating. You may be risking a blowout at anytime.

Lots of answers, too bad most don't know what they're talking about.
If it is over 5-6 years old, I would suggest getting rid of it as someone noted above, the rubber deteriorates over time from heat and polution. You should replace tires in pairs, if possible, to provide stable handling.
It sounds like a tire over-inflation problem, but without a picture it's hard to tell.
I've listed a couple of websites below to explain treadwear patterns along with pictures. Some types of treadwear indicates alignment problems rather than tire or inflation issues. Alignments are best done with new tires, or at least tires that don't have any improper treadwear on them.
Hope this helps.

A concave tire indicates that somewhere along the line it was under-inflated. If your driving on the wear bars across the tire edges by all means replace it.
Keep tires inflated to the recommended pressure as indicated on the tire, not the car door pressure. Car manufactures want to provide their customers with a soft mushy ride. They don't give a hoot how the tires are wearing. Learn how to read tire-wear. The tread should have even wear across the tread. Shoulder wear inside and out indicates under inflated tires. Too much center bar wear usually means narrow rims and or under-inflation.

The useful life of a tire, whether it is worn out or not, is 6 years. This tire is not safe, the rubber will be brittle, the tread will be dangerous on wet roads, and it has not been inflated properly in the past. Toss it out.

Concave in the middle is not overinflation, it's underinflation. When the tire is low on air the center of the tire puckers up and the tire actually rides on the outer edges.

Its a sign over inflation. Don't use the tire, is your life worth $50.

you mush have 3/32nds to mount it. If the sidewall has a dimple looking spot running downward on the tire that is a spot were the plys of the tire meet it is acutually the strongest part of the tire. You can really only see them on tires that have very little design on the sidewall.
