Tuesday I brought my first jeep. I got a brand new '11 wrangler sahara. The problem I am having is finding grip tires for the 18" rims. The few I have been able to find have been really expensive. I'm not looking to do a lot of hard core off-roading but i would like to go to a few mud holes here and there. I was wondering how well jeeps perform with all-terrains. Mine came with Bridgestone Duelers. In the trucks I have had in the past I always ran Firestone Destinations and have never had an all-terrain tire so I am just wondering how much mud can they handle?
