I've specced my '14 with the 22" alloys, but as mine will be a HSE Dynmic, coming with 20" brake calipers, what 19" winter rims will fit the new MY14?

I have 20" general grabber AT's on my current MY10 for winter use so I might just stick with 20s but the consensus is 19s are better for off road use?

Thanks MY10 HSE 3.0 TDV6 : Santorini Black : Ebony Interior w/Anigre wood : Privacy Glass (total) : Sunroof : Sidesteps : Hybrid TV : Detachable Tow Kit : Spare Wheel Cover : 22" Dished Supersports
