Looking at a 2015 Mazda CX-9…Any issues?

[PTguy]

I've been running 17" KIA wheels on my 2016 CX9 with snow tires every winter. No problems. Be sure the offset, bolt circle, and center bore diameter are suitable. (KIA, 'cuz I had them already) As long as the tires are within about 2% of the original tire outside diameter and load rating is OK, it's good.

Bolt pattern on all Mazdas in NA are the same, 5x114.3. Centre bore is 67.1 stock offset is not n the 45-55 mm range on the cx9. The RTX centre bore is 73.1 so I just need new hub rings.
As for tires depending on which generation cx9 I go with I will be fine as I know what size I need. It just depends on what all weather/all terrain tire I get

For All Weather, I recommend the Toyo Celsius. I've gone through 3 winters and they performed very well.

My brother in law is running the Falken Wildpeaks on his Jeep and he can’t say enough about how good they are in the snow
