read full thread, my initial wheel choice does not meet the required load ratings for the CX-90 PHEV

Hi guys,

I have a Canadian CX-90 GS-L PHEV, meaning 265/55R19 oem 3-seasons.

After much research / discussion, I'm going with a -1 setup for winter, using the oem GS MHEV's 255/60R18 size, as opposed to a 265/60R18 which would be a perfect diameter match with the oem GS-L's 265/55R19. Mazda uses staggered sizes, the original 18, 19 and 21 inch tires all have different diameters!

So the idea here with the smaller fitment is to provide a proper combo of wheel offset / tire placement in the fenders. We'll see how PMC Tire's advice pans out as they guarantee their fitment. Going with the oem 19" size would have increased my budget by about $800 CDN.

Wheel is the DTD Blizzard - same brand as my Crosstrek's replica wheels which have held well after one winter. Wheel is rated as a "direct oem fit", hubcentric and all. Cheap at $169 CDN each.

Tires are Toyo Observe GSi-06, same supplier as my oem 3-seasons, and tires that were fantastic last winter on a Ridgeline that I reviewed under a week where winter threw everything it had at us.

Kit shipped ready to bolt, will have to wait a bit for the programming due to how new the CX-90 is, but will test-fit front and rear as soon as it arrives.

The tpms sensors are not oem units, but a prime aftermarket brand. They need to be programmed for the vehicle they are installed in. From what I learned in CX-5 discussions, the vehicle can "learn" the new sensors and not require an instrumented "learn" at each tire swap. The 2012 Odyssey the CX-90 replaced was like that, and I ended up having the tpms light on all summer as I kept the winter sensors active. Hoping the car is smart enough to store its 8 sensors with no outside help!

In Quebec, snow tires are mandatory by law, they have to be on the car by December 1st - in any case, we need them anyway with all the snow and ice we get! Getting a head start ensures no supply issue and less worries. PMC Tire was the only outfit to guarantee the fitment, hence I went with them and the price was good ($2k + tax for the whole thing, mounted and balanced, tpms installed and programmed, shipped to my door). I will report here on how they fit once they arrive - there's a delay since they're waiting for the tpms programming because of how new the vehicle is. Going with the dealer, they talking $400 tires and $400 wheels, but had no idea yet on what fits...

Thanks very much for your post and information for those who need Winter wheel and tire options. Yes, there are some choices for wheels and smaller diameter does open up more selection and lower prices for both wheel and tire. Further, there can be less weight for the wheel and tire yet they function very well in winter conditions vs OEM sizes. The optional Blizzard wheel is 2" less in width which helps it cut through deep snow and lessens rolling resistance.

Some specs and options for DTD Blizzard wheels- comes in Black or Silver finish and multiple wheel offsets but not all will fit the CX-90
18x7.5" 5x114.3 bolt pattern, et42 with centerbore 67.1 (matches OEM centerbore, other offsets have centerbore which is smaller than 67.1 so they would need to be bored out)

Comparing the 18x7.5" et42 wheel with 255/60-18 tire to OEM-
The inner rim will be 28.4mm further from inner suspension, outer rim will poke out 22.4mm less, ride height will be 8.9mm less, speedo error is 2.3%, at true 60mph it will read 61.4.

Overall it looks good, let us know how you like it. Any idea how heavy the wheels are? Or even the weight of each wheel/tire combo?

For winter tires in 255/60-18 besides the Toyo Observe Gsi-06:

Light Truck/SUV Studless Ice and Snow tire
Bridgestone Blizzak DM-V2 $214 each
Tirerack test result-
Yokohama Iceguard G075 $188 each

Performance Winter Snow tire
Vredestein Wintrac Pro $201 each
Tirerack test result-

As a car reviewer, I get to test all sorts of winter tires on all sorts of cars every season. The Toyos on a Ridgeline were very impressive, and while I'm a Blizzak guy, the older DM-V2 made a Subaru Ascent skittish in the snow. The Yokos are cheap, but even places that sell them warn me of uneven wear. Do look out for the load index - the CX-90 PHEV requires at least 109. Most tires in the size I bought are 112's, but you'll see plenty of 108's that should not be mounted on the 5200 lbs Mazda. My Toyos are 112, while others were stiffer 114's.

Guys, I will do a proper thread later on, but having received my mounted and balanced 18" winter kit this week, I just completed front and rear test-fits and it works !!
Great, please include all the wheel specs including load rating and offset, tire specs and overall weight of wheel/tire. Pictures would be good and your impressions when driving.

Do note that these are directional tires and that I mounted one "wrong" just for the test fit in the back. We're in the middle of a 100 degree heat wave this week, waaayyy too early to install these tires right now!

PMC Tires includes a deep socket for the wheel nuts free of charge when you purchase wheels from them, and indeed the DTD's are pretty deep. For the test I properly seated the wheel with the wheel lock (deeper) and made sure that it turns. So 18" will work, but don't even think of trying anything smaller.

Also, the way the suspension arms limbo into the wheel up front tells me that a proper offset is critical here. If you buy different specs, make sure the fitment is guaranteed.

Since ordering my winter kit, Mazda has added an accessory 18" wheel for the PHEV so the minus one fitment is now factory endorsed!

Hoping my research will serve the CX-90 community as I could not find any of this out there!

Not trying to worry you in any ways but looking at the load rating of your wheels of just over 1500lb, you're way below the minimum of 900kg (1984lb) load rating that Mazda are stating. I had PMC change my initial order of 19ich Fast Wheels to go with the RWC wheels to make sure I respect that minimum rating. Seem like the 900kg is way overkill from Mazda though....

French is fine for me (I am a French-Canadian after all!), for the others - it appears that Mazda does not recommend the use of steel wheels on the CX-90.

Do you know the source of that image? Is it from Fastco?

I will reach out to PMC as I'm a bit worried now - they should have caught that.

Well I had to change my order before it was shipped from PMC and thankfully the order was not fulfilled so I was able to change it. I had 19inch Fast Wheels Impression wheels at first but ended up with the only suitable 19inch wheels from PMC which were RWC MHK369 (925kg load rating). I would suggest you reach out to either Mazda Canada or your dealership to check with them if the safety notice is still valid. Again I've seen numerous owners going with different wheels than the recommended M016 wheels from Mazda (Mazda M016 Alloy Wheel (Metallic Black) — 18", 19", 21") and I'm sure they would be fine. Obviously if anything was to happen with the wheels, damaging the vehicle, I'm sure Mazda would point to lower rated wheels and not honor the warranty if that safety notice is real. Therefore I suggest you check with Mazda and have them confirm the information. I'm no expert here and I'm only going by what forum members have told me. I just didn't want to take any chance and went overkill.

I asked PMCtire about MHK369 - Black - 18" x 8" since it load rating of 1820lbs is lower then the recommended 1984.16lb. here's their response. I was asking for a PHEV GT.

Indeed, the MHK369 is one of the rare models that is recommended for the CX-90 considering its gross weight.

The wheels is recommended as a perfect fit for the CX-90 by RWC directly, meaning the wheel passes all requirements (clearance, load capacity, OE lug nuts, etc.).


it seem that manufacturer know some info on the load that we dont? i would liketo go for the 19 inc too, since it exceed the 900Kg, but not available at the moment

News from PMC. One of the owners called me. He checked the matter first with a Fastco engineer as they are an oem supplier. Fastco indicates in their response that typically the industry went for GVWR divided by 4, while oem's will spec GAWR. In the CX-90 PHEV's case, the GVWR is 6854 lbs and the highest GAWR is at the rear with 4090 lbs. That's 2045 lbs/wheel in the back and nobody, not even the accessory wheels made by Fastco will reach that. Since I will never tow, GAWR is probably overkill but GVWR is not with a 7-passenger. PMC feels the DTD wheel is safe at 1518 lbs. However, GVWR/4 = 1714 lbs. So PMC will replace a cracked wheel or will replace everything if I'm not at peace. The DTD wheel is at the limit with 782 lbs of cargo, passengers and fuel on board, not including cornering loads - I will probably swap, but I'm waiting for Mazda's input. The Fast "Switch" was what I wanted initially ... and it's rated at nearly 1800 lbs. Bonus: same grey as the oem alloys. Stay tuned!

And here is Mazda's tech dpt answer:
"The wheels this customer has installed are rated at only 75% of the required load requirements of the CX-90.

There is a risk the wheels would not stand up to impact load in the event of a collision, putting the occupants and other commuters at risk.

The only wheel options Mazda Canada can recommend are the factory supplied wheels and the Fastco M016 which was made available to order to our retailers in Q2 2023."

The Fast M016 is rated at 1984 lbs no matter the diameter and is indicated as "sold out" on Mazda's website. I inquired back to them about using GVWR/4 as I scrolled through all options and while there are a few in the 1797-1819 lbs range, nothing goes further.

Seems like Mazda is being very keen on the 900kg minimum load rating. For those that are looking at budget winter wheels, so far only the Braelin BR08 and the RWC MHK369 in 19inch will meet the minimum load rating requirement. Both are between 275 to 320 CAD per wheels which is still cheaper than the M016 from Mazda.

Did some math. Going with PMC pricing, keeping the oem 19 inch size with the RWC MHK369 wheels and same pick of Toyo winter tires totals 2150 CDN. The BR08 is a gorgeous wheel but it adds up to 2400 CDN. Keeping my 18 inch « minus one » fitment with Toyos and the Mazda-supplied M016 is 2407 CDN, not counting mounting and balancing which would be extra here. Tires are 50-100 more from 18 to 19 but it is what it is to meet factory specs 😕

I just received my wheels with tires mounted from PMC. The setup is 19x8 RWC MHK369 with Toyo Observe Gsi-6 in 265/55R19 with rubber valves. Total weight per corner is 72.6 lbs which is quite heavy as not only are the wheels about 9 pounds per corner heavier than the M016, the Toyo tires are very heavy at 39lbs per tires. I'm not sure what the stock 21inch wheels/tires weight but I'll guess around 65lbs. At least I'm confident that the wheel can withstand normal use.

Whoa! Looks like I’m not going to find any set of wheels under 1000 CAD. Will have to resort to getting winter tires fitted onto the same rims. Not ideal, but I reallly don’t wanna end up spending over 1600 just for the wheels.
It's tough on a budget, just looking at tirerack.com for the CX-90 (any trim level)
Firestone WinterForce 2 UV SUV Studdable Winter Snow tire
265/60-18 $172 each, 110S load rated, fits rims 7.5-9.5" wide, perfect for 8" wide rim
Studding $15 per tire optional

Sample wheel for package to match tire
Sport Terrain TK13 gloss black painted finish $186 each
18x8" et35, 25.75 lbs each

These are decent and will function for winter. An option.

Update:

I have changed my Rim selection to the following which meets the Mazda recommended load rating:

I don't want to compromise anything by saving $200 over the Fast Wheel FC08
