Grab the tire firmly where it's low. Squeeze/push/roll the

Does it matter whether it's fully inflated or not?

There are tools for that:

but strong hands alone will seat most.

Thanks (and to sir) for the advice.

What all this sounds to me like is that you have "two-way" or
"tubeless" rims and Continental tires will not work properly
with those wheels. They are clincher tires. Continental is
presently working on tubeless tires and they are expected to be
released next spring.

Except the bike is about four years old, and the rims worked okay
with previous Continental clincher tires--just different models.
