I had denali wheels on my 04 crew cab, was running Yokohama AVS S/T's but in the 275-60-17 size. Looked pretty good, I only had 2" drop shackles. I wouldn't necessarilly suggest the tire, it was pretty good, great wet traction, but the tread life absolutely sucked.

 

damn, those look great on the Denali wheels.

As for the 285's....Toyo recommends them on a 8" wheel minimum, so I think I'll stick with 275s
