Yeah they will fit your 06 with no problems. I know a few guys that fun stock clutches with no problem. Those tires are really light but an almond secondary would probobly be plenty. I am sure someone that runs them can chime in with their set up.
I have ran 30" mudlites for about 2 yrs with a 2" highlifter kit. I got a little rub on the front left when I turned hard left. I also had the shocks tightened all the way up. I use a highlifter extreme clutch kit and I could spin them like crazy, the lites are easy on the drive train.
