Just so that people who wonder about this know. Our CX9s are equipped with TPMS (tire pressure monitoring system). When rotating tires, you DO NOT need to reset the TPMS. Here is what I found after some research. - if your vehicle is capable of telling you WHICH tire has too low pressure, then, chances are you need to reset TPMS every time you rotate tires (such as some high-end luxury vehicles like Acura RL or Lexus LS) - if your vehicles is NOT capable of telling you that (like our CX9, which only shows a warning light), then, you simply rotate the tires like you used to do. I just rotated the tires over the weekend. 100 miles later, no light at all. Google search before I did it gave me confusing information. Therefore, I post the correct answer here to share with you all. When changing to new tires, make sure you tell the mechanics not to damage the sensors connected to the valve stem. They are pretty expensive. There is no way to turn the TMPS light off permanently since it is against Federal law. For those who use winter tires set, you either have to buy a new set of sensors to go with them or simply ignore the constant light of TPMS that shows up in your dash. According to the WorkShop Manual, our CX9s pressure sensors inside the tires sends signal to the central antenna (same one as your SmartKey or non-SmartKey receiver). The sensors do so once per hour and after the speed reaches 25km/h (15.5mph). "Once per hour" so that the little batteries inside the sensors can last 10 years. I can post the procedure to register the new sensors if anyone is interested. I believe it is also in your owners' manual so I omit it here. |

I'm in the market for a CX 9. I thought I wanted the GT until I read all the posts about how awful the tires are in the snow. I live in Maryland and only occassionally get snow so snow tires aren't a great option. I'm wondering if I should get a Touring instead. Any thoughts?

| I have an 08 CX-9 AWD that I've had for just a few weeks. Yesterday and today, we had snow and ice in the DC area, and the 20" tires did just fine- so far. | |

Replying to: seaweed20 (Jan 28, 2009 1:25 pm) OE tires (Bridgestone Dueller H/L) are not cheap tires. It listed $200 on tirerack.com (while Yoko Parada Spec-X is ONLY $160). So, MAZDA was not trying to be cheap here. It is just that they chose summer performance over snow. The OE tires work well on dry and wet pavements. Also, make sure you choose a CX9 that is manufactured as late as possible (see the stickers on the base of B-pillar) so that those TSBs (see another thread) don't apply to your new CX9.

Replying to: seaweed20 (Jan 28, 2009 3:29 pm) The Yoko Parada Spec-X are more truely all-season tires. Both are all-season ones. Unlike snow-tires, they don't wear very quickly in summer. Yoko Spec-X has wear index of 460 while OE one has only 260. That means, by federal testing, the Yoko lasts almost 2X longer!
