Front wont follow rut!

I have a 2005 YZ250 and am having trouble riding rutted corners. The front tire wants to ride up the side of the rut and will not follow it. I still have the stock front tire on but that will hit the trash soon (any suggestions on a replacement). I ride mostly hare scrambles but like to do motorcross open practices. I have comp at 16 out and reb at 8(?) out, also I raised the forks 5MM in the triple. I remember reading something about the rebound affecting riding ruts, and also the front tire being a problem, but I cant find the thread. I have no problem ridding these ruts on my old YZ or my friends CRF450 so I don't think its me. Any help is greatly appreciated!

I weigh 220lbs, I have a Race Tech 5.4kg spring in the back and stock up front. I am reasonably sure my sag is at 100mm w/static sag at 25mm. Like I said I hopped on my buddies stock(except tires) CRF450 and had no problem riding the ruts.
