Rack and pinion by design eliminates the general need for a stabilizer- thats why you dont see much if any conversation about it. Larger heavier tires, wider rims and lift will impact steering geometry. The best you can do is improve your alignment to increase caster for improved return to center and straight line tracking.
I’m stating the obvious here but by going to larger, wider, heavier tires expect poorer handling, increased stopping distance and anticipate increased wear on upper/lower ball joints, steering rack, TRE’s, tires and brakes.
