Well, my dealer has offered to test the fit of my 16" Ronals for me (although I usually do the winter/summer change myself, it will be nice to have the dealer test the fit for me).
I'm starting to think that they will fit just fine.
- The rims fit my old G35 Sedan (Sport 6mt), eventhough Tire Rack doesn't show 16" as an option on the G35 Sedan. And the QX50 is essentially the G35 Sedan, but higher.
- 17" used to be standard OEM rim for EX, so 16" would just be minus one.
- 215/70R16 tires would be less than 1% off from OEM 18" and 19" tires.
- Noticed that Nissan Rogue which is very similar in dimensinos to QX50, has 215/70R16 as one of the OEM sizes.
Will post results after I had a chance to test the fit of the 16" Ronals at the dealership (hopefullly within one week). Ronal are top quality rims and hard to find now in North America (as Ronal no longer distributes after market wheels here, focusing instead on supply OEM wheels and after-market in Europe). So if possible I'd like to keep them for the QX50 as winter rims instead of selling them for a fraction of their value. I have the 19" wheels that come with the Premium package on the car now.
Here's pic of the Ronal rim:
