Let's denote the cost of each of the first three tires as \( x \). According to the deal, the cost of the fourth tire is $5. The total cost for the four tires can be expressed as:

\[
3x + 5 = 237.50
\]

Now, we can solve for \( x \):

1. Subtract 5 from both sides:

\[
3x = 237.50 - 5
\]
\[
3x = 232.50
\]

2. Divide both sides by 3:

\[
x = \frac{232.50}{3}
\]
\[
x = 77.50
\]

So the cost of each of the first three tires is **$77.50**.

Thus, the correct response is:

**$77.50**
