I can't think of anyone who has said "Balt More" in the local area. The pronunciation varies but a common form is "Bal Ti More" where Ti can be a range of things. The T is never attached to the Bal part in pronunciations I hear regularly.

Bal is usually pronounced as "Ball" or "Baw".

The Ti middle part is represented by Teh, Deh, Tee, nothing at all, and more. Lots of variety here.

More is pronounced as "More" or "Mer."

Some combinations are much more popular than others.
