you are rubbing because of the offset of the wheel and the Readylift UCA. The UCA has a very prominent bend in the leading arm, exactly where the rub is .
I have the same set-up. I had the 285/45-22s from the factory (+24 offset wheels) and they rubbed. I welded on the lower steering stops from a Zone kit. Those limited steering just a bit, enough to eliminate rub. there was about 1/4" between the tire and control arm after. I figured with new wheels (less offset +18) and same width tire (285), I would clear just fine. well I was wrong. the new 285 is much wider than the factory, they rub good at full lock. I have wheel spacers (1/2") but I don't want to run them. I am not a fan.
If you get the steering stops from a Zone kit (just call them and they will sell them to you), weld them on, you will clear the arms.
After studying pics of the Cognito control arms, and comparing them to the Readylifts, I am pretty sure the tires will clear. The Cognito leading arm has a much sharper, straighter angle to the ball joint. It is not rounded like the Readylift. The new arms will be here tomorrow, and I should have them installed by next week.
