I see the '12 Keystone Cougar 327 RES shows a 11945 GVWR which may mean a 5.2k axle rating on the trailer.
The ST235/80-16 E tires are 30.7" diameter.
Many folks replace them with a LT245/75-16 R that has a 30.4" diameter.
The LT245 E tire has a wider section width so measure close. LT tires on my 11200 lb trailer have 1" between the tires and 2 3/4" clearance at the top and 3/8" on the inside next to the shock.
