another yes they will fit, and another yes they rub in the back with flex,
33, 12.5 with offset rims for mine, bought it with them on.
Next rubber I want 33, 10 (or something) and I have a set of 2 inch lift old man emu's to put on.
Hidden behind the flare, I have a little bit more room than Copenhagen1 seems to have, but not much more.
They can be made fit.. These are 33x10.5.. Measure slightly less than 33.. I have redrilled spring perches 40mm rearward and opened up the wheel arch by the same.. The arch is stock height.. The wheels tucked under on articulation but a dip in the road at speed will cause the tyre to contact the guard.. The guard has since been raised to a point above where the PO had hammered the guards in attempt to make 33x12.5 fit, and another 40mm rear.. As can be seen the tyre doesnt fit inside the well properly and sprays mud all up the side.. Flares are recommended. The tyres are mounted on 15x7 rims with normal offset.
I know you said 33x10.50s, but here are 33x12.50s with 2.5" lift springs and 3" over stock shackles in the rear. (Meaning 1.5" at the axle, plus 2.5" lift spring, equals 4" at the rear. The front did not need a longer shackle because it sits higher due to a lighter engine than stock.) Anyway, the rear wheel wells aren't cut. they're just barely adequate for off roading, and for serious articulation, like for rock crawling, the clearance is inadequate. It's also inadequate for chains. The chains clear - until you hit a rut. I may wind up going to 4" lift springs.
