Can I use CX-9 winter wheels on a CX-90?

Hey,

Considering upgrading my CX-9 to CX-90. I have a good winter wheels with 255/55/19 winter tires on them. Can I keep them for CX-90?

Numbers look acceptable, did Mazda change offset or smth?

Looks like CX-90 stock 21" offset is also ET45:

18x8" et45 20.97 lbs/9.51 kg
19x8.5" et45 23.17 lbs/10.51 kg
21x9.5" et45 27.98 lbs/12.69 kg


Comparison with my winters looks acceptable, but might be a bit narrow.

I think it's doable. Backspacing could be a concern but I don't think the 90's brakes are big enough to cause fitment issues.

Make sure the ID of the rim has clearance for the calipers.

So long as it clears the calipers like someone else mentioned, i think it would be a good choice for your winter set.

going narrower is a good thing for snow traction.

ideally you would want a a 60 aspect ratio if running 255/XXr19, to bring the rolling diameter close to stock, but you're correct in pointing out that the difference is still going to be within range.

I know this has been a common belief but it has been tested and shown to not be the case. Don't worry about seeking out narrow wheels and tires for the winter.

Yea i've heard this a lot but I'm not sure if it is true.

I am wondering is my 205 width winter tires will be wide enough for my tuned FWD 6. Stock is 225. I wouldn't mind going up to 235 for my summer set due to the tune.
