I just bought a 2020 XC60 with 235/60 R19" tires. I have been told by the service department that the manufacturer does not recommend chains of any sort for these tires. I still have a set of Sentra Chains that I used on my 2016 XC60 235/60 R18" tires. In the instructions it says they will fit 19" tires. Has anyone tried using chains on their 235/60 R19" tires?
