All is good in the end though. no rubbing at all. The taller sidewalls do WONDERS for the ride, and they render the steering a bit lighter (lots of reviewers are complaining on the too-firm steering in follow-up drives). Plus, the CX-90 looks bitchin' with these wheels:

With the larger diameter tires, actual mileage and speed will be different than indicated mileage and speed, no?
 
Where does one find wheel info for offset, bolt pattern, minimum wheel weight capacity requirements, etc. I looked through the 711 pages of the manual <ZZZZZZZ> and couldn’t find any info. I have a Turbo S with 21” wheels, and am trying to figure out what the recommended options are for winter wheel/tire sizes, offset, etc as well as what my stock wheels are. I‘m aware that Tire Rack lists various diameter options, but I’m wondering if there are specific Mazda recommendations/requirements.
 
You won't find the wheel specs in the manual.

OEM 21 x 9.5 J ET45 - on front and rear

Tire 275/45-21 Tire diam. 30.7"


If you go to Tirerack.com and put in your CX-90 model and trim you can choose what size wheels from 18" and it will give you various sample options. For Winter both 18" and 19" wheels and tires will fit and work with your Turbo S. Tirerack has already determined which wheels will fit. Using their wheel specs you can go shopping on your own. Some Canadian owners have posted sources they used for Winter wheels.
Many thanks PhEVuser! Quick question; you reference bolt pattern 5 x 114.3mm above - a search on Tire Rack using our vehicle yields their suggestion of wheels which are 5 x 114mm …. Is the .3 difference insignificant?

Also, I’ve seen comments about “-1”, which I understand to mean 1” diam less than the vehicle wheel. But is the thinking that one shouldn’t go beyond “-1”, i.e. Not less than 20” if you have a 21’ wheel? Or does that not matter, and its basically a matter of what sizes will fit
