First, welcome to the forums!
Now, on to business.
Tire size is ST225/75R15.
National Seal number: H73336550, Napa #473336
Number of lug nuts per wheel is six, if you are planning to replace the wheels, make sure you get wheels with 2500 lb. capacity, and zero offset.
Brake parts, if you need them, are standard fare, and come in 10" and 12" diameter, if you need to replace the brake magnets, the originals have round magnets, and replacements are oval-shaped. The oval ones are more powerful, so you will need to replace them in axle pairs.
I don't know the bearing number, but the number is stamped on the bearing itself, so if you take an inner and an outer with you, you should be able to interchange them.
