well i am going to put some nitto nt555 on my truck bu i am not sure what size tire to run. have a 2-4 drop on the truck with an overall height of 31 in tires on it now. i am not sure if i need some smaller tires when i go with the nittos. i am putting them on some steel 16 or 17in rims

 

I am running the 305/45/18 on 18x9.5 wheels with a 2/4 drop and it looks good. You are going to be hard pressed to find a drag radial for a 16" rim over a 26" diameter to fit on stock width wheels. M&H has a decent size drag radial for 17's and a 28" tall 16 that will fit on stock aluminum wheels.

 

do you have any pics of the wheels and tires,i have a 2/4 drop on a 03 rcsb gmc sierra but i cant find a 17 or 18 inch wheel that is 9.5 inches wide anywhere
