Yeah 35"s should fit ok.
I had 34" JT2's (measure out to 34.6x11.9") on 15x8" ROH Trac 2 rims and had no rubbing on the rear and only scrubbing on the front if the car hit a hole too hard (with a bit of lock).
I had a 2" body lift and 2.5" suspension lift.
With a 3.0 V6 & 5sp (yours will have 4.88 diffs) you will notice the lack of power especially up hills but being a swb and 200Kg lighter you maybe ok with it. Mine being a lwb was a pain and I was going to go to 5.29's anyway (even if I didn't do the SAS).
Now with 5.29's it helps but is still no substitute for power the 3.0 V6 doesn't have much low down torque which is the problem.
Having 2.85 t/case gears with 5.29 diffs low range is great.
Your economy will go out the window and if offroading hard you will regularly bust IFS stuff (bend idler arms, break tie rods, bend steering arms etc). Your speedo will be out quite a bit but you can get other Mitsu speedo cable gears to compensate

I didn't break anything with 33"s but certainly did with the 35"s.
The extra clearance is awesome just what a IFS Paj needs but there are side effects and it really depends on what you want to do with your rig and how much $$ you want to spend.
I was at the end of the road with mine with the IFS couldn't really run any bigger tyres and the IFS was starting to suffer big time and required a total overhaul or replacement (SAS).
