I bought chains specifically for my CX-9 GT AWD and have since sold the vehicle. I never used them, but had to carry them since the CHP in California requires it. I have seen other Mazda CX-9 owners use these same chains with no problem. These are mainly designed for vehicles with very limited operating clearance around the drive tires. Very easy installation with no need to move the vehicle and include "designed in" rubber tighteners. As I stated, these are brand new and come in a canvas storage sack (still have factory plastic seals). They are Security Chain Company part number SZ435 and fit a variety of tire sizes (check out the SCC website). Paid $112 for these...call me at 909-597-5021 and make me an offer.
thx, Danny
