I have no experience with tire chains. I have driven many times in snow and ice in the past but never got to the point I needed tire chains. This year I have planned a couple of trips into the mountains to snow mobile and ski. I want to be prepared so I am looking at buying 2 sets of chains. My vehicle is a 4wd 4runner. It has full time 4wd. My main question is can I run a more aggressive set of chains in the rear and a less aggressive set in the front? The reason I ask is due to my vehicle being full time 4wd and my front tires being larger than stock rub a little bit as is without the chains at full lock on steering. My rear does not rub at all.
