In the manual it states not to use chains with the 20" rims. (page 4-10). Look at getting the 18" rims installed in place of the 20". My dealer (Colorado Springs, Colorado) gladly installed the 18" rims on my GT. You may also find a slightly better grip with the tires on the 18" rims as they have a slower speed rating which equates to slightly softer rubber.

Forget chains, just get decent winter tires. I run my CX-9 GT on 18" tires during winter here in Sweden. With today's technologies, no one has used chains in the Nordic countries since the dark ages - besides which there are illegal in certain areas. Vredestein Wintrac Xtreme seem to fit on 18" rims with no problem.

The local ski hill 25 miles from my house is a bit more than 2100 metres high. Kebnekaise is about that - I wonder how many steep roads you have compared to the Sierra in California where chains are commonly required?
 
Tahoe is at 1400 metres and the grade on the interstate going up to Donner Pass is steep, sometimes as much as 6%. Donner Pass on that route is 1818 metres and it's not the highest road pass in California. On one trip over, we decided to hit a motel late in the day and take our chances on clear weather the next day to avoid buying chains.

We bought Blizzak snow tires for our AWG GT. They were very expensive as they are 20" wheels - $289/tire! But they make a huge difference. First very light snow we drove the car with the factory (non snow) tires (with only 3000 miles on them) we slid through the first red light. That prompted the purchase of the Blizzaks and they made a huge difference.

I've heard that the Snow tires like the Blizzak work great in show/ice, but are terrible on dry pavement. How have yours done on dry pavement and how is the wear? I live in Denver, but go skiing often, so in 90% of the driving is on dry pavement in the city and then the weekend jaunt into the mountains (which is often dry highways, but some snow on side streets.)

20" Wheels - Ride Quality by belaircarguy

I just purchased a 2008 GT with the 20" wheels from my local dealer in Maryland. I did read about the ride differences between the 18" and 20" wheels and recommendations to take a drive in both vehicles before deciding. The interesting part here is that I have only had this vehicle 2 days, and was checking air pressure in the tires of my old and trusty Isuzu Trooper. parked right next to the CX-9 in the driveway. I thought perhaps I should see what the pressure should be in the CX-9. Door post showed 34 PSI recommended. The tires were actually inflated to 45-46 PSI. Once adjusted to 34 PSI I took the CX-9 for a spin around the neighborhood and could feel quite a difference.
 
Obviously my local dealer never checked air pressure before selling this car, but even more concern is that I could have taken this car out on the highway for a long drive and perhaps blown a tire, due to over inflation!
 
I had read previously that auto makers do over inflate the tires, as the cars ride better on the car carriers. Not sure if this is true or not, but it certainly points out the need to double check everything once you have it home!
 
So far the CX-9 is great! Love the handling - reminds me of a sports sedan!

I've had my ride for 9 months - I've taken it to the snow, the dirt, the city and the highway - the 20's I drive on are Sweet. No problems, unless you switch tires everyday for where you'll be driving, these are superior all-around tires.
I don't find them noticeably noisy, or hard or soft to any material difference.
 
If you compare them to racing tires or Off-road Desert Tracker tires, yes, you'll notice a difference, but for an all-season $200 tire, you can't go wrong.
 
Good luck and Hit it!

Blizzaks are great in the snow-ice and will transform your CX9 in to a proper winter driver. In another post, I commented and felt the CX9 was unsafe with the stock 20s for winter driving due to vehicle weight and tire width, and immediatly went to a good set of snows to protect my 40k investment. The snows are not bad on dry roads but they are soft walled and made with soft rubber and if driven hard on dry roads will wear accordingly, especially warm-hot dry roads (read no snows in the summer!)... The deal with Blizzaks and like tires is the first half of their tread life is the best due to soft silica compounds, sipes, and pourousness of the rubber. Bottom line is the outer tread is really sticky when it comes to snow-ice handling and they will wear very quickly on warm dry roads. I live in Upstate NY and put snows on in December and take them off in March and will get 5-8 seasons out of a set of Blizzaks. I retire them with about 40% tread life left, even though they look good, and are safe but they do not do the same job as when new and I need the traction when it comes to deep snow and icy roads as I live in a lake-effect snow band. As the rim size goes up, the tire price does too. Because of this, I run smaller rim size tires with snows which also reduces the performace feel. MY CX9 AWD came with 20"s, I ebay sourced Mazda 18"s from that had TPS and had tire racke drop ship Blizzaks to a local installer. I now have two sets of tires, 20's with OEM tires for most of the year and 18"s with snows for the winter. No breaking them down every year to swap them, and they get rotated and both wear longer, and have TPS in both sets so no idiot lights either not to mention the 20s will never see road salt. I also have a 01 FWD Jetta with 16' BBS summer rims and 15' trash rims with Blizzaks for winter. I love the handling of the summer tires and love the traction of the winter tires BUT, like the CX9, it is a different car when I change tires and I drive accordingly. The CX9 and Jetta actually ride softer with the snows, with a little bit more noise, and I never push the car in turns because of the tire. The cheep side of me also babies the snows so I can get many seasons out of them too. Hope this helps

I saw the manual states the 20" don't support chains, but the clearance looks adequate. I don't think it would be any better with the 18"s. It has more clearance than our old Sienna where we used cable chains. Any one have an opinion or suggestion of where to get chains?

The tire diameter will be the same with 18's or 20's so there will be no diffeence in clearance. The rim size changes the tire profile. recomend you buy a good set of Blizaks (4each) if snow performace is required
