Mazda CX-9 Tires and Wheels

    Look at this page. - - - atio=50&diameter=20&x=11&y=9

    Pay attention to prices vs scores (red numbers).
    You will see why many are recommending Yoko Parada Spec-X (score=8.4)
    I just had it installed a few days ago. Much better tires than OE lousy tires (and for $200?! Bridgestone must be smoking something funny... score is 4.8!!!)

    RS-A (H-rated) is at least cheaper with score of 5.5. That is at least a good trade-off from Yoko Spec-X. If you take your CX9 to snowy areas, I would highly recommend the Yoko Spec-X (see reviews from users with millions of miles on them). If you only drive it on dry and wet, RS-A may be good enough for you. Again, it depends on where you drive it.

    I would like to get the Yokohama Paradas for my 2008 CX-9 grand touring, but the 245/50-20 are out of stock for months.

    I read on another forum that the 255/50-20 size would be an acceptable alternative.

    They are 1.3 % larger (?) in diameter, according to an online tire calculator.

    Does this all sound right, before I have them ordered?

  • You should be fine with this alternative. The reason the tire is 1.3% larger in diameter is because it is also 10mm wider (255 instead of 245). Therefore, instead of being 122.50mm high from rim bead to tread (hence (50)% of 245), the alternative will yield 127.50mm height (50% of 255). The only thing it affects is your speedometer which will be reading 1.3% slower. i.e. Your speedo will read 60mph when you are really traveling 59.22mph...not a very big change.

    Hope this helps!

    I second the opinion.
    However, some tire places will refuse to install non-factory size of tires for you.
    I bought from and have them ship to a local "authorized installer" (listed on The local shop usually does not care.

    Do yourself a big favor. Get rid of that lousy tires ASAP and send Mazda a complaint email about it. I did.
  • 25,000 miles and the 20" tires on my 2008 cx9 gt are pretty much shot. Not looking forward to the cost of replacements.

    We have about 20k miles on our tires, and when I do the quarter-in-the-tread test, it comes to the top of Washington's head, which means there is 4/32" of usable tread. This might explain why we're slipping a little more in the snow than last year, every website I read says that you need 6/32" of tread for adequate snow driving (which would be the top of Lincoln's memorial on the penny test, and we're nowhere close). So 25k miles is probably as long as we'll have ours, just like you.

    The OE tires do suck, wore out rather quickly, and they got loud quickly. In fact, I'm beginning to believe that most performance all-seasons just suck. I have a Mazdaspeed 3, and the all-season tires I bought a year ago are basically at 3/32", and that's only 16k miles. I can barely get out of my snowy driveway, never mind trying to get up steep hills, or trying to brake down those hills. So I threw in the towel and bought a winter tire package, and I'm going with dedicated summer tires in warmer months. I wonder if I should do the same with the CX-9...
  • Someone on another Mazda thread commented that the AWD CX9 has more problems than the FWD version. Anybody else heard that?
  • Hi, I am looking to factory order a new CX9 GT and live in a snowy part of PA. Does anyone have experience with having the dealer switch out the new tires on a vehicle before delivery to something that may work better in the snow? I would like to have the Yohohama tires on the car when it is delivered to me. Is it asking too much to expect the dealer to absorb the cost of the tire switch? I would think it shouldn't cost them much since they would get to keep the OE tires.

    I have a CX-9 with 20" wheels. It's a fun car to drive. But it's wider than I originally thought and I'm having some trouble turning. The rear of the car seems to pull away from the direction of the turn even when I do a soft turn at 35 or 40 mph. Is this just an issue of me getting used to the car? I've been driving an '01 Pathfinder for a long time; know how to drive an SUV. Is the problem the tires? If so, will the Yoko do the trick? They seem to be extremely popular on this forum.

    i have 20" wheels and have no such problem. i would get that checked out.
  • All -- after reading the many recommendations for the Yoko Spec-X tires, I ordered a set (245 for 20" rims). I've had my CX-9 for less than 3 weeks; first snow was earlier this week and the car skidded all over the place.

    Only Nevada had the tires in stock. They're supposed to arrive in a week. Question: many of you have said that the tires are out of stock; so, is the Nevada option a crock? Also, are the Yoko tires better in the snow than using 18" rims with snow tires? Are they at least comparable in terms of traction? I'm not as concerned about road noise and feeling bumps. I'm just interested in making smooth turns on dry pavement and feeling secure in the snow/ice.

    Also, is it better to downshift or brake on snow/ice.
  • 1) If someone says they have Yokos in the right size and the price is right for you, i don't think you can assume it is a crock. typically many of us look at for availability and reasonable pricing (that is where i got my Pirelli scorpions). tirerack inventory on ANY tire can change day-to-day. one day the website told me Yokos were backordered until Dec 2009 and then the next day they were available in early December.

    2) Yokos are not likely better than snow tires. snow tires are the best for traction. the problem is that you would typically not use snow tires year round thus you will have to seasonally change between snow and summer or all-seasons. that can be a pain if you don't need the utility of snow tires so some people (like myself) just want an all-season that can handle a little bit of snow and ice. although, ice traction will always be a problem for all-season tires, Yokos included.

    just my opinion.

    I presume you ordered from as they have a Nevada warehouse.

    I've dealt with them exclusively for tires for that past 10 years and have never had an issue with them. If they say they are in stock in NV, I would believe them.

    When I ordered mine, it said 12/24. However, mine were shipped to me around 12/10. I was surprised by I also did business with them for more than four times. Very decent internet dealer. Lots of info on wheels and tires on their website.
  • I'm here with my AWD CX-9 in an area that is dealing with the blizzard of of '10. The streets have been plowed leaving a thin layer of ice and packed snow on the ground. My CX-9, with factory installed tires, performed remarkably well after getting out of my driveway, where it struggled with the buildup of snow that the plow left behind. So, in what setting will the Yokos really improve my control over the car? When there are 1 to 2 inches of snow on the ground? When snow is actually falling? When there is pounding rain? Is the benefit over time as Yokos are much more durable? I understand now that the Yokos don't compare with snow tires, but I'm trying to better understand where people have really felt the difference.

    I took my CX9 with newly installed Yoko Spec-X up for skiing last month.
    Felt very secured on all situations. Of course, I did not take it off roads other than paved roadways or around ski resort.

    Based on the customers' review on, the Yoko Spec-X is better in all aspects than the lousy OE Bridgestone Dueler. H/L.

    Very heavy storms a few days back in Bay Area. Love my Yoko as well.
    Perform seamlessly w/o slippage or hydroplanning.
  • I just had tires on my new CX-9 replaced -- I now have the Yoko Spec-X. After the installation, my TPMS warning icon is showing (the little, boiling pot with an exclamation mark in it). Will this go away after a while? Or do I need to take the car back to have them adjust the sensors?

    Also, I've already got a little dent in the cheap, sort of plastic runner underneath the front bumper. The recent snows along the East Coast have taken their toll on the car! Have you heard of people getting dents in that runner popped back out or does the whole thing have to be replaced.

    Read the owner's manual.
    There is a section describing how to reset it.
    If no luck, the one who installed your new tires might have damaged the sensors while doing the mounting. :(

    BTW, the icon shows a cross-section of a tire with a "!" mark in it, not a boiling pot. :P

    What are the best 20" Mud & Snow tires as replacement on a 2010 AWD.
    Don't want pure Snow's.
