these tires do fit, you might need to pull the fender back a little, bt that i mean the lip/plastic peice in there.....there are a few people in the forum already running this size
Keep in mind that those are Bias Ply tires. With the mileage that you drive daily you might run into some comfort and longevity problems with the TSL's. Other than that they should fit with only the Melt Mod
I had the superswamper tsl on my old cherokee as all day tires. they wore out very fast, I lovd the sound of them, and you could here me coming from three blocks down, crappy in the snow. Again very short road life, but great offroad and very nice and hardcore looking. I'm thinking of getting another interco tire for my X and TJ.
The Thornbirds are not going to do very well on the road, or in snow, or in sand... or on rocks... but hey, they do look cool.
If I were you I'd go for these. They're on sale right now too.: http://www.4wheelparts.com/PDT63296.aspx
