I have a Subaru Forester XT 2017 and want steel rims and higher tougher walls for off-road trips
I have checked with SUBARU and they have 17 inch rims at R541.00 each.

Currently I have the standard  225.55.R18  which gives an overall diameter of 27.74 inch or 70.46cm

I believe I have two alternatives on 17 inch rims:

225.60.R17  which gives an overall diameter of 27.63 inch or 70.18cm

225.65.R17 72.44cm which gives an overall diameter of 28.52 inch or 72.44cm

The first alternative reduces height fractionally but will maintain the torque - I think!

The second gives almost an extra centimetre in clearance but will slightly reduce torque -I think again!

It is a given fact that odometer and speedo will be incorrect with either choice but this does not worry me.

Despite assurance from SUBARU what is your opinion and which tyre size would you choose?
Could this affect my warranty?

I can not comment on the warranty. Subaru SA must answer that.
The turbo and CVT should handle the slightly "longer" final gearing with ease.
However I have found that both "higher" sidewalls as well as the move to "all terrain" tyres do somewhat negatively influence your road-holding. There are no free rides, it is a trade off.

I agree with JBH - I'm running slightly "oversized" AT tyres on my turbo auto Foz and yes, both acceleration and on-tar road holding are respectively slightly and noticeably compromised, but I'm happy with that trade-off in favour of a bit of lift and tougher tyres for offroading.
I needed to slow down anyways - fuel and tyres are expensive, as a speeding fines!
Current: S-edition 2011 Steel Silver (S-exy young thing) - Forged, Chett tjooned, 76mm s/s wrapped DP, King Springs, 225/60/17 G012s, Sump & AT guards, cheap mud flaps, HID fogs, LED parks.

Can I ask why not 16" rims?
I think you will have more choices and cheaper tires so you could probably get 6 tires for the price of 5.

As a guide i use

And here is a comparison same tire in different sizes:

I went 16". Never look back.
Went from a 215/55 R17 to a 215/65 R16.
Much more comfortable. Gained 9mm in ride height.
Grip from the Geolander G015 tyre is incredible. And only a slight compromise in corners when one is pushing on a bit.
Added bonus is the tyres are almost half the cost of the 17"
So what is not to like?
