Thanks.
Find another tire store. Only the 4.2 came with 18" rims, and even that model can accept 17" without issues.
The challenge in finding steel rims is the offset. Not too many cars out there use 25mm offset with 5x112 bolt pattern, in fact, the Allroad is the only one.
Just buy the steel rims based on the specs you need instead of choosing by model. You may have to run 10 mm spacers.
Or else get another set of authentic Allroad 17" rims from someone else or ebay.

Investigating used OEM rims, but shipping cost can be prohibitive up here. I will search for the rims using the figures provided, thanks. I'm new to the whole spacers thing, can you elaborate?

I use Dunlop SP Sport 01 with 225/55 R17 and the are a good bargain for the money, at overwhelmingly on-road conditions.
The grinding noise you mentioned at very sharp cornering at low speeds comes from false alignment and according to my mechanic, often inappropriate choice of oil in the torsen differential (after changing the OEM one)
Overpressure at tires put extra load on the air bags I would not do it, but depends on how good the asphalt surface in your region..

Sorry for taking so long, didn't see your response.
Offset is the distance between the centre of the rim and the hub. The greater the offset, the more the wheel is tucked inside relative to the hub. Allroad offset is considered small, being just 25 mm, so the wheel sticks out more.
If you buy an average rim, it will likely have an offset of 35 mm to 45 mm, meaning that it is tucked in by 10 - 20 mm more. This will present a problem, since the tire will rub on the inside against suspension components.
A spacer is inserted between the rim and the hub along with longer bolts to counteract this.
So if you buy a rim with a 35 mm offset, you will need a 10 mm spacer, so the actual offset is 25 mm.
Take a look at the Wheel & Tire tech section on http://www.1010tires.com
It explains it all and a lot more in greater detail.

You can also use the 16" spare allroad wheel with regular tires. If you can find four of these you may have a wider selection of tires that will fit for the smaller diameter.

That's an idea too. For now, I have the winters mounted on the OEM alloys and am searching for another set of alloys to get the all seasons mounted on. Both sets of tires are basically new, so not looking for a different rim size (yet).

Do you have experience with a somewhat special size of 215/65 R17 ?
I could have a very good bargain for all four as brand new - for the Winter season (TS810 Continental).
So, the diameter would be just on centimeter more than of the 225/55 R17.
The raising questions are
- Eventually, the Level 1 clearance from the fender with the currently used the 10mm distance places (so ET15) due to the non OEM rims
- More important: wet / dry grip with 1 cm less width.
- last but not least the bonus one: /65 on the R17 and curves
Thanks in advance!

People have run this size since it's narrower and much better for snow.
I can tell you that running 235/55-R17 is not that stable in snow at highway speeds. Seems there is too much tire for the weight of the allroad so it doesn't cut through it.
Of course, being in Toronto where roads are plowed and salted, the extra width proves useful when dry or wet.
