Here's a picture of the gap between my stock 33" tire and the Hi-Lift Mount, which looks to be about 4 inches. My guess is the biggest tire you could run with the Rotopax/Hi-Lift setup is 35", but hopefully M3 will confirm!
For those of you with the maximus-3 tire carrier, do you have an uncovered space as large as this at the top of the hinge?
I'm pretty sure I pushed the hinge up as high as it could go. The slots in the holes for the hinges are horizontal so you can adjust in and out not up and down so even if I loosened the hinges and tried to move them up, the best I could get is 1/16".
Now the bottom hinge only has about 1/8" gap.
I also had to slot the plate(pic below) to get it down lower. The hard plastic cradle piece didn't have enough adjustment.
As far as the hinges that attach to the tailgate(not the tire carrier hinges), they line up perfectly as expected.
My door closes perfectly though. Way better than before.
