Tire Size for Icon Mid-Travel with Stock Off-Road Rims

About to start installing a Mid-Travel Icon kit on my 2005 Access Cab 4x4 Off-Road. The kit includes 2.5 ext. travel front c/o’s, billet UCA’s, 2.0 rear shocks (remote resi), All-Pro expo leaf pack, All-Pro U-bolt flip kit, and Wheelers super bumps (front and rear).
While I’m doing the install I’m having a buddy weld in TC Cam Gussets, TC Coil Bucket Gussets, TC Spindle Gussets, DMZ motor mount gussets, and a cab mount chop if necessary.
The truck already has an ARB bumper on the front with a warn M8000 winch I put on after I struck a deer about 2 years ago.
I’m pretty set on getting BFG KM2’s but torn between 255/85R16 or 285/75R16 on the stock Off-Road rims. I think I’d rather go with the 285/75r16 but worried about it rubbing my billet UCA’s and ARB front bumper. Anyone have a similar set up, or knows someone that does?
Will the 285/75R16’s work on my stock rims if I set the front at ~2.5” of lift?
Also, if this should be posted in another section please let me know (couldn’t decide between general, suspension, or tire thread).

Looking to do the same thing. Subd

 

They will work, but I'm pretty sure you will need spacers. I have the same size lift and plan on running 285 70 17 km2 on my stock sport rims as my play set of tires/rims.

 

Already have a set of 1.5" Synergy Mfg. hub centric spacers. Just don't want to use them if I don't have to...

 

I had some correspondence with an Icon rep about this and was told that you will need spacers to run 285s on stock wheels. The X-Overland guys run 285s and, while the Icon guy couldn't tell me which ones, they do use spacers. Although, I don't think they are running the TRD Alloys anymore. I'm not sure if the Billet UCA has different clearance issues, but this is the case for tubular. They say a max of 5" backspace, but recommend 4.75".

I'm also eager to know how your kit works out. The Icon rep suggested the 2.5" rear shocks for overland builds, but I wouldn't mind saving some coin if the 2.0 with res will hold up well.
