I also have a 21 Lonestar 4x4, added 2.5" motofab leveling spacers and 295/65r20 on stock night edition 20x9 wheels.
I went with Yokohama Geolandar MT's. On the truck they measure out to about 34.75" tall, and 11.8" wide. My biggest concern for fitment was with the upper control arm. Stock tire was very close to the UCA, with maybe 5/8" of space between the ball joint and the tire sidewall. But after the 2.5" level the Yokohama's fit with around 3/8" of space now, and clear at full lock either direction. The tires also clear at full lock everywhere else within the wheel well, and just narrowly miss my mud flap in the front wheel wells.
The Motofab 2.5" kit also worked out pretty well. Stock heights I measured out at 39" to the center of the rear wheel well, 36.25" to the center of the front. Now after level and tires I'm at 40.75" to the rear and 40.25" to the front. So still a tiny bit of rake, though it has the illusion that the front is high.
No rubbing anywhere. clears front of the wheel wells, clears back of the wheel well with the small mud flaps. Only place it rubbed was when reversing and turning the wheel to the left, the passenger tire would catch the thin plastic inner wheel well liner. It was curving outwards likely due to engine heat and it curling. I snipped off a 2 inch section with some scissors and fixed that.
