[nobbyq]

Use something like willtheyfit.com to compare with what you have now, then go outside with a tape measure and see what it looks like.

As dubber says, but offset needs to be linked to wheel width which you don’t state. To achieve the same flush look, as the wheel gets narrower, the offset decreases.

Offset does not always decrease to wheel width. In fact it isn’t linked to wheel width at all

What he means is "To achieve the same flush look, as the wheel gets narrower, the offset needs to decrease."

Err, you might want to read what I wrote a little more carefully

I've recently fitted some Fuel Zephyr swamper style wheels to my T6 which are 8.5J x 17 ET 34. With 225/55/17 "road" tyres the fronts are probably on the limit for arch protrusion or poke as I think it is called? I certainly wouldn't be comfortable with them being a lower offset.
The rears could probably take a 10mm spacer without going too far. I have a set of 5mm spacers to go on but need some longer bolts first.

I have ET35 on 9.5J all round and whilst the rears are fine ( I could have gone 10.5J to fully fill the arch), the fronts are only just legal. The added drawback of this is spraying even the slightest bit of road crap up the side of the van when it's wet, and whilst my mud flaps help, narrower wheels (or narrower offset) would help more!

would et 40 poke out past arch ?

What size wheel?
Have you tried putting the sizes in Online Wheel and Tyre Fitment Calculator. Offset, Tyre Stretch and Speedo Error | Will They Fit ? That would give you an exact number for the amount they would poke out and you could measure it against your van.

This is my front set up with the 8.5J et 34. Not the best background I admit but it's where the van is currently parked...
