A good size tire for these wheels

[FlameOut]

I currently have some old dry rotted 33 x 12.5 x15's on my 72 K10 (they are probably 25 years old), but am now working on cleaning up the wheels and will need new tires. The 33 x 12.5 seemed to fit just fine, and looked good, and no clearance issues on my stock stance K10

I guess these wheels are 8" wide? Or would they be considered wider? I thought it would probably be measured from inside lip to inside lip

What's a good aggressive looking tire that would fit and look good? Checking places like Tire Rack and Discount Tire, there are many many to choose from. I was leaning towards the BFGoodrich All-Terrain T/A KO2, but not sure if I need to be concerned with things like load index, speed range, etc.
