Bought my 9 about 4 months ago---GT AWD. When I buy a new vehicle I typically buy a 5th matching spare alloy and tire to replace the temp donut from the factory. This allows me to do a five way rotation to make the whole set last longer, and gives me the option of continuing on a trip if one tire goes instead of being forced to stop and repair the tire nearly immediately, since the donuts are only rated for about 50 miles or so. So  today, after getting my matching 20 inch rim and waiting several weeks for the special order matching tire to arrive from Japan, I go to exchange it for the donut, only to find that the device that dangles from the cable under the rear and goes through the center hole of the wheel is bigger than the hole in my alloy wheel (fits the steel wheel fine since its hole is bigger). Anybody got any solutions?

Is there someway you can use a steel chain attached to the down cable with weatherproof locks (to protect from road debris)? Maybe you can thread it through the new rim and attach with a steel bar that can fit through the opening and be locked in place with u bolt or other. |

It is much tougher to find a tire chain for 20" wheel. In fact, the manual recommends you not to install tire chain on the 20" due to possibility of chains scratching the wheels. So, there you have it. The only upsides for the 20" wheels are - better cornering (shorter side-wall) - look Other than those, 20" wheels are heavier (even combining with tires), which is bad for a lot of criteria (stopping distance, acceleration, MPG, etc.) Add the difficulty to obtain tire chains (actually you could, but they are usually more expensive than the 18" one). Besides, the seller does not guarante that there will be no rubbing between chains and wheels (due to short side walls). Just my two cents. |

We recently purchased an AWD CX-9 GT here in Vermont. A couple days after buying the car, we received about 10" of snow from a storm. The AWD did fine, but the tires definately needed to be swapped out for proper winter treads. We had already ordered Bridgestone Blizzaks and 18" alloy rims (you can find a set for about $1,000 for both rims and tires at Tire Rack). We put on the Blizzaks - a very popular winter tire up here - and they made a profound difference. We also have them on our Subbie Outback, which can go just about anywhere. If we bought the same Blizzaks for the 20" rims, the package would have cost the same and we would not have the benefit of an extra set of rims. The tire companies make a substantially higher margin off tires for larger rim sizes. Now the 20" wheels are in the basement until summer and the winters will get only half the use (they are sharp looking too). |
