Dago - to be clear, this is a truck I am considering purchasing. The fatty MT wheels scare me a bit (feel free to chuckle ) Seem like a large cost to replace and may very well cause the drive to be unsafe? Or have I heard wrong? Driving in rain etc. Can they hold up to sustained highway driving? I would have to drive this truck some 800mi to get it home.

To answer your question this is the info I have:
narrowed 9" rearend, 15X5" rim with 15" tires on front, 33x19.50x15 Micky Thompson Sportsman rear tires.

Any info or experience you can share would be awesome. I had been tossing around the idea of just ripping out the entire rearend and replacing it to match the front end tires.

Am I nuts?
