No, that's a waste of money. There are two resons to replace a tire:
•The tread is worn thin so it gets punctures more easily.
•The fabric is damaged so that the tire is misshapen or lumpy, or the
tube bubbles through a gash.

There's not actually much difference in puncture resistance among tires
of similar tread thickness. You haven't said what sort of things you're
getting punctures from.
If your problem is small glass slivers, there may be some slight benefit
from a belted tire.
If it's nails or the like, tires vary in nail resistance in much the
same way as different types of t-shirts vary in bullet resistance.
By the way, it is a dangerous habit to translate tire sizes back and
forth between decimal and fractional notation. As it happens, there are
no decimal sized 27 inch tires, so calling it "27 x 1.25" isn't as
dangerous as it would be if it were, say, a 26 inch tire.
Whenever you see two tires where one is marked with a decimal and the
other with a fraction, you can be sure that they are _not_
interchangeable, even though the nominal sizes may be mathematically
equivalent.
See:

If you do decide to replace your tires, we have an excellent selection
of 630 mm/27 inch tires, see:
