I'll photograph the wheels and post the photos later today.
As for the tires, all of which are ST225-75R15(E): 1 General Tire (0 miles purchased last month as my spare), 2 Towmax (purchased at JC Nov 2013), 1 GYM (purchased at JC July 2013) and 1 (Westlake, purchased October 2011 - had been my spare until last month). Tires are rated Load Range E, max cold pressure rated 80 psi, and I run them at 65 psi.
There are 5 rims, but only 4 hub covers, as these fit into the rim before the wheel is mounted, hence no need for a spare hub cover. Rims and hub covers are aluminum.
I travel about 12-15,000 miles a year with the trailer (TV runs 22,000 miles per year).
