i am going to lift my 84 toyota with a 3in suspension lift and a 2inch body lift. the lift says with the 3in lift that i could fit 33.12.5 could i fit 33's by 15.5. and with a 2inch body lift after the 3in suspension could l fit 35in tires.

With just a 2" BL a 33 is going to rub, and a 33-15.50 is going to be even worse it's an awfully wide tire. It's going to rub the frame in addition to the wheel wells. You'd need rims with very little back spacing for starters. If you wheel the truck it's going to be even worse. Plan on trimming sheet metal.
