Yes the standard offset is ET30, P30, +30. If you put on a P0 wheel, the centreline of the wheel will move outwards 30mm. However, if the wheel is say 8", then the outside of the rim will be a further 0.25" outwards.
If you want to stay legal, most states will only allow a track increase of 26mm. Half this and you will only get a change of 13mm in offset allowed. So for the 120, the legal wheel offset is ET17 to ET30.
I have a 150 GXL and my dad has a 120 GXL. He has a set of Cooper ST/MAXX tyres on a spare set of 120 GXL wheels that he's not using (nor likely to use in the near future) and I'm wondering if I can pinch them.
I understand that 120 GXL wheels aren't legal (but will fit) on a 150 GXL because the track decreases by 10mm (ET30 vs ET25).
From reading the whole thread I gather that increasing the track by 10mm is ok - so 150 GXL wheels should be legal on a 120 GXL. Is that true?
If that's the case I might swap his Cooper tyres across to my rims and try to source some spare 150 GXL wheels in case he wants his tyres back for a trip!
I just measured the wheels that came with the camper. I thought they were P30 for a 120 but the wheels are the same as above. dynamic 17x8 P25. So I could have left these on the camper... But the alloys look better and have KO2s and not KOs.

I have new camper trailer approx 2 weeks from pick up and it has
dynamic Hi8 17x8 with p25 offset (black) and I am thinking about putting the same on the Prado.
