The regular price of each comic book is \( r \). Since each comic book is discounted by \( 1 \) dollar, the price of each comic book after the discount is:

\[
r - 1
\]

Since Ron bought two comic books, the total amount he paid before taxes can be found by multiplying the price of one comic book after the discount by 2:

\[
2(r - 1)
\]

So, the expression to find what Ron paid before taxes is:

\[
2(r - 1)
\]
