i got the 275/65/16 on stock rim. i have the hotchkis 2/4 drop and it looks ok to me. i think mine are the same heighth as yours (vortech5300). check out the sig.....

 

Finally got out and measured mine. 17"x8" with 275/60/R17 BF Goodrich. They are 29-3/8" rear and 29-1/8" front, guess the front squishes them more. I would like to have bigger rims($$$), but like 29" overall. Trucks with smaller even if lowered have too much gap in front and back of tire in fender. I had 2/4" drop and it still had rake, but looked good, even fender gap on front, the back had more gap on top that in front and rear of tire.

 

Hell Phat Cheve, yours looks perfect like that! STill got a little rake to. With the formula, your 275/65R16s show to be 30.1", mine show to be 30.75" So about 3/4"-1" tall which is 1/2" less gap on mine. Not to mention yours are a wider, rounder profile which makes it look better then my squared off profile Michelins. Sidewall to sidewall they are pretty wide but tread patch isn't near as wide and it looks like a square. HMMMM How much was the Hotchis 2/4?

 

When I first did the drop I had the 275/60/18 on there for about a week before I got my new tires. Those were 31" tall and they looked ok but I did rub them once while they were on.
