D'Addario oud strings are gauged for Turkish ouds, but as with most Turkish sets, they can also be used on Arabic ouds (~ 61 cm scale) tuned a step lower. D'Addario's information included with the strings can be confusing. It's printed to reflect Turkish notation, which is written a fourth higher. In other words, the highest course listed on the package is "g". In typical western lingo, this is actually "d". In the chart below I've listed the more familiar western eqivalents to avoid confusion.
The two lower courses are listed on the package as F# and B. A fourth lower means you can tune these pairs to C# and F# or E and A. For the discerning player, tuning these pairs up to E and A might yield higher tension (but not too high by any means). In that case, individual gauged strings are available below.

D'Addario Gauged Nylon Strings

For those wishing to assemble their own custom set of strings, or swap out individual courses from any set of strings.

D'Addario rectified nylon and silver wound on nylon strings are unsurpassed in quality. D'Addario Pro Arte classical guitar strings are the best-selling classical strings in the world, and both the Pro Arte strings and the Gauged Nylon strings are identical in composition

and performance. They are, in fact, the same strings. These strings are an excellent alternative to the popular Pyramid lute strings. They are also less expensive. A custom set of D'Addario Gauged strings can be assembled for less than $20. Prices are per single string.

D'Addario Single Strings Tensions: PDF Table
This table includes tension information in kg, Newtons, and lbs. for all the D'Addario strings. You can easily determine the tensions for the strings based on note and scale length. Scale length (in centimeters) is listed at the top of each table. For scale lengths between whole numbers, e.g. 61.5cm, simply average the given tension for 61 and 62 cm scales.
