A 15"x8" or 15"x10" with 4" or 3.75" of back spacing. I'd go with a 15"x8" with either back spacing.

Easy enough.

15X8 is what I use and I like the extra bulge to help keep the rocks off the rim. Bead bustin I want no part of.

so long as that 33x12.5 tire has a 15 inch rim diameter... 

It should read 33x12.5 r15  {toast}

[Krawler00]

Will, 16" would be a 285-75-16. 16" and up read different from 15".

You're diving into all this a little too soon it seems.  Do a lot of research before you start spending money. But the tire place is retarded. The most common rim size for a 33x12.50 tire (in the offroad world) is a 15x8. You want "buldge" as you mentioned, when off roading. When you air down your tires for more traction, the sidewall of the tire will be "pinched" on the rim and help to keep it from losing its "bead" or seat on the rim.

that still doesnt answer my question.. tho.. should i get new rims or not.. i do about half and half so.... which one?.. 15x10 or 15x8

the tire place is going on the recommended size rim for that tire size.  going with the recommended size rim you will be able to run the recommended tire pressure for your vehicle for normal wear and tear.  now a narror rim and a wide tire is going to buldge more so your going to have to run a lower pressure on the street in order to get a good contact with the road which will lead to a little more slop in the handeling (probley not enough to notice on a DD with the tire size in question).  off road as said above it should help keep the tire seated a little better at lower pressures.  if it was me i would go with the 8" rims, in fact that is what i'm running currently running with 36" IROKs (sort of), when i bought them they were 15x8 then i added DIY Bead locks which makes them closer to a 9" rim now.
