biggest tire size?

[Marlin]

A word of caution on these "fit like a glove" statements - 32" tires with zero lift will fill up the visible wheel opening on a flat road, but you need to consider the effects that full articulation may have if you plan to do any offroading. That is some nice dark cladding you have there H3, would be a shame to crunch it the first time you go crawling.

Others can offer much more direct knowledge and experience, just throwing it out there as food for thought.

32s on OEM offset will not touch cladding. 34s at OEM offset will rub in the front and rear on full flex on the points of the wheel wells, but not crunch the cladding at the top. That is at OEM ride height. I don't know about the rear since I am lifted 3" or so.
To fit the 34s, I had to do some trimming and pounding, but it looks fine unless you look inside the wheel well from underneath. If they are looking under my skirt, there are worse things to see other than my pounded steel.

There ya go - I fixed if for you, big boy.

Damned spell check, it always "screws" up my point.
