Tires - Because I often travel heavy, I had a lot of trouble with the OEM Goodyear Marathon 14" tires. Went to Marathon ST225/75R15. No problems in several years. I love 'em, but I've not used any other so I have no standard of comparison. The new Goodyear Endurance is reported to be even better. They are both available from any Goodyear dealer, and most tire shops either have them or can get them quickly.
Wheels - I can't recommend any specific wheels, since I just bought the standard white-painted color-stripe 5-hole (called "5 on 4 1/2") 6-inch steel wheels that everyone, including my tire shop, had in stock. As you drive around, start noticing the wheels on trailers. You will see these wheels all over the place. However, be sure to look inside the wheel (the part you can't see when the tire is mounted), and find the weight rating and the pressure rating. They must be at least 2200 pounds and 65 psi. More is better. There are some identical-looking cheapies out there.
This one from etrailer looks good, though the price is a little higher than I expected. Also, you must have your tire jockey remove the rubber valve stem and substitute a bolt-in steel stem. And once the tires are mounted, be sure to have them balanced. Don't take "we never balance trailer tires" for an answer.
