wheel well trimming

Just got my new 2017 tundra platinum and added a 3" front level lift and I put on RPB94R 20x9 wheels with 295/60/20 nitto grabbler G2 tires, I was told they would fit but hard turn left or right they rub. I am kind of cautious of trimming in the front of the wheels. Remove all mud flaps, has anybody have this set up. the back is still about a inch lower than the front, would I need a lift block to get level! Any input would be a great help.

Go with a new shackle from coachbuilder to lift the rear

 

what is the offset on the wheels? did you already remove the mud flaps? it sounds like you are going to have to trim.
