Manufacturer does not recommend, but you can add S type cable chains which are low profile.
Check clearance first before buying.
Just don't use the trucker linked chain type.
Only time I would consider putting on cable chains would be if I had to climb up a steep ice slope that a set of winter tires won't grip.
Tire chains are a pain - that's why I got the Discovery and dumped my Mercedes 4Matic.
I noticed the Discovery has a much better full time 4WD system instead of that crappy all around common AWD on demand that all the German, Japanese and American cars have these days to save on wear/tear. I much rather have full time 4WD instead of having an AWD computer determine if the other axle should turn on...
Just get some good winter tires like others here have done for all around snow, slush, and light ice or if you want to go extreme, get a set of studdable winter tires where you can screw in studs when you go extreme.
I use the Bridgestone Blizzak DM-V2 with lots of success where I go fishing and skiing in the winter....
