Purchased at Canadian Tire for $170 plus tax for my 2011 Volvo XC60. Here's an Amazon link - https://www.amazon.ca/Security-Chain-Company-ZT729-Traction/dp/B000BR8UAO I've never used them because I got really good winter tires after this purchase. They fit on a number of tires (see photo and link for specs). Cash only, please.
