Looking at Keystones Cougar web shows the 331 series Cougars have a 12xxx GVWR and come with ST235/80-160 E.
The unit may come with 5.2k or 6k axles. If thats the case then any of the LT235/85-16 E or LT245/75-16 E would be the best tire upgrade for that size trailer. Going with the LT will get you away from ST tires and their issues regardless of brand.
