tire rub upper control arms / need a better fitment wheel to prevent this?

hello all,
I have a 2003 Toyota Tundra 230,000 miles on my 4.7 L V8 2 inch leveling kit up front 1 inch in rear. stock wheels 6 lug 16 inch. although my issue I am running 285/75/16 which cause rubbing of the upper control arms. I tried 1 inch spacers, not enough thread to hold on! Does anyone have a solution to my wheel replacement issue! or if I could find the wheel studs longer for the adapters? a few of the best things I've done replaced all fluids for lube with full synthetic/ drive shaft failed from no grease zerts? Ron's Machine Shop in Utah chop the ends and replaced with grease able Dana U Joints. Bed Rug, always/ gun safes mounted in the cab also in the bed, regular preventative maintenance service. I live at the beach so salt air is always present.
