This was my '04 with a 3" RTE lift and 255/85's. No trimming except for the bumper. Could defintely fit 315/75's with moderate trimming.

 

I really appreciate it for all the heads up. Thank you for the warnings because I am a disco a noob, but boy I'll tell you one thing I love them like I know every thing about them. From what you said I decided that I should go ahead and invest my money on 4 in springs and shocks, extended brake lines, and an aftermarket driveshaft and settling with 33's as well. 35s would be nice but I don't want to harm the cars performance as you just mentioned. It's going to be a lot of money but it will be worth it.

 

Sweet ride, Buddy. I'm jealous dude.
