thanks for the help, especially the pic of the blue xj...mine is blue too lol. i might go with 235/75's just to play it safe. i have a shot at trying the 30x9.5's my buddy is putting them on a yj, so i asked if i can throw them on my jeep first to see how they fit...

 

I have a 2k XJ with 235 75 15 and they fill the wheel wells at full flex.

 

I have the wrangler duratracs 235/75's. I drive mine daily to work. I love these tires. they are quiet for the most part. when the radio is on you can't hear them at all. I have this thing about tread patterns. the grouping and out line is something i look for. I do like alittle hum. I wish these were alittle bit noisier. But they are very livable as a DD.

I hate street style tread on our cherokees. its almost sacriligious, a slap in the face to the jeep gods, if you will.lol. Finding a happy medium was not easy, til i found these.

they are excellent in the snow and rain and they have an aggressive tread pattern.
I get 19-20mpg in mixed driving but babbying it.

here are some pics. just took these today.
