I own a 2 door Sport S have the upgrade that includes the All Terrain (vs All Season) Goodyear Wrangler tires. I've been thinking about upgrading to Rubi take off wheels and BFGoodrich KO2 tires. This weekend I'm taking the Jeep up to the Sierra's and there is supposed to be a pretty good storm. If I change out the wheels and tires, will they be significantly better in the snow? I'm a bit worried about the weight of the 2 door on mountain roads. I know chains will help but would prefer to buy the new wheels and tires, if they are significantly better, then buy chains for the new ones. Thoughts?
