#84 of 121 CX9 18" wheels
Dec 20, 2009 (11:11 am)
Can anyone confirm that Mazda RX8 OE 18" wheels would fit on a 2008 cx9? All the specs that I can find on the net are the same - 5x114.3 lug pattern, 12mmx1.5 lug nuts, 67.1 hub diameter, 18", the only spec I can't confirm is that the RX8 wheels are also 7.5" wide. I thinking about buying a used set, and use them 3 months out of the year for snow tires. Anyone know?

Hello, did you get the RX8 18" wheels and put thme on your cx9? I'm considering the same thing right now, for snow tires. The nice thing is that you can get a nice set of used rx8 wheels with TPMS for a nice price. I just want to confirm they fit properly and have appropriate weight capacity. Please let me know. thanks, Jim
#86 of 121 Suggestion on New Tires for CX9 Grand Tour
Dec 25, 2009 (9:37 am)
I need new tires for the CX9 grand Tour. Any recommendation on which ones are good. The dealer is telling me to replace it with GoodYear Eagle RS-A.
I have a 2007 CX9 Grand Tour

Look at this page.

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.
#88 of 121 alternate size?
Jan 05, 2010 (7:03 am)
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 tirerack.com and have them ship to a local "authorized installer" (listed on tirerack.com). 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?
