He is probably referring to the adjustable camber bolts. You should not have to have this done unless your truck has been lifted and is way off alignment. I lifted the front of mine 2" and the camber/caster was still dead on. Only the toe needed to be adjusted.

 

If you are looking for an aggresive tire look @ Maxxis Buckshot tire 275-65-18 is $200.00 a piece.

Love me some BFGs A/Ts, I think they are sweet lookin, sure are expensive though!

 

BFG AT`s or Toyo AT`s

 

Those of us with 18" rims don't have alot of options if we want a slightly larger tire then factory. When I was searching, BFGoodrich A/T, Michelin and Nitto were the only A/T tires available. I had the Nitto Terra Grappler on my Super Duty and I was happy with their performance. I recently put 285x65x18 Nittos on my '09. They are E load rated so they do not ride as smoothly as the factory LT tires, but so far I am happy with them.

 

Can you post some pics of your truck with the Nittos?

 

another good looking "aggressive tire" imo are the khumo mud tires. i recently put a set under my jeep, thanks to some super ebay deals!!! i have had no problems and they are much quieter going down the road than i had expected.

 

x2 on that, those are really great tires with a nice tread design and still have a somewhat "beefy" look to them for being A/T's. And yes they are extremely quiet and will last forever, I put 10k on a set on my 04 heritage and never noticed any sign of tread wear.

These are 305/70R16, a little bigger then what your looking for but you can get an idea of how they look.
