Look into the Nitto 555R in the 285/40/18, they are over 27" tall. I also had my rims prior to tires and I mocked them up on car. I took a piece of pink insulation board and cut a cross section of the tire dimension and mounted it to the rim (duct tape) and installed it on the car. I then fully rotated the rim and checked for all clearances. Make sure to have your suspension loaded (jack under axle on test side) and car level, also do both sides as most are slightly offset to the left or right....
