I'm looking to get bigger tires for my 2012 liberty and was wondering what's the largest tire I can put on the stock rims with no lift kit. I was initially going to lift it but I've decided that I wasn't going to keep it as long as originally planned but I still want to have good tires for going on some of my local class 6 roads which are usually rocky and muddy, also decent in snow. Any advice on sizes and brand/model would be appreciated!
