Thanks for the advise, but if I never go in snow which size would you recommend is better?
Again, there are a bunch of options, all come with compromises. For example, I have 5 months of winter here, not that much snowfall but enough, and a lot of icy roads. I have dedicated snow/ice tires, in stock size (225/65/17). I don't off-road, don't hit unplowed trails, so I don't need flotation on snow at all. 225 is the narrowest acceptable on the non TH Cherokee, I would not go wider, for winter.
Your case is much different : no snow where you live, but snow in higher elevation where you might want to go skiing, correct ? That's a difficult situation because of the small amount of time spent driving in winter conditions. Can't really justify getting snow tires and your regular road (all season) tires aren't really designed for snow and ice, so... if you decide to install A/T tires, those would provide better snow traction than your road tires, for sure, but wouldn't really be better on icy roads.
But if you spend weeks in snowy areas, then... you could consider an extra set of wheels with winter-friendly tires.. On a TH, you could install 235/65 or stock 245/65 (17) size, for winter tires.
