My 33" tires with 8" rims on a 2.5 inch lift rub when twisted. I have warflairs front and rear and I don't rub them. The tires will rub on the beams in the front, the rear of the front wheel well where its welded to the side panel need to be cut back to where the wheel well is spot welded other wise you have a knife edge ready to slice through the tire at full stuff. The rear wheel well will rub in the front of the inner wheel well that's OK as long as you fold the side lip out so it doesn't slice the tire. I also rub the top outer edge of the inner wheel well but it does no damage as that area is smooth. As said above new limited bump stops could keep everything from rubbing. This is with 33" tires with 35" they will fit but rub sooner. 10 inch rims would make it worse. If I really wanted to go to 35" tires and keep the 2.5" lift I would relocate the rear axle back an inch. This would require a relocation block for the spring perch and probably a new extended driveshaft. Since most people already stretch the stock drive shaft for the 2.5' lift.
