2010 XC60 Looking for advice on snow chains

[sandyegg]

Hello everyone,
I have a 2010 XC60 AWD T6 and need to buy snow chains for it. Is it possible to use conventional chains or cables or must I purchase the very expensive "Centrex" style? My tires are 235/60R18 Continental Crosscontact LX20's and I'm concerned about not having enough clearance for the conventional chain/cable ones. Thanks for your help!
