Must I change all 4 tires together on a cx9 awd 2010 ?
I have heard that on certain vehicles you have to change all 4 tires at the same time because it might affact the "all wheel drive" system...
Depending on the wear on the tires, you may have too. The tire shop will determine if all four need to be changed. If there are a lot of miles on the tires, then all four would need to be changed.
