One week ago I took deilvery of a 2006 f-250 SuperDuty Crew Cab Short Bed diesel. Trirm is Lariat, auto trans. When driving at highway speeds all is fine going straight, when I start to go around a curve, it try's to DECREASE the radius and go off the road. This happens going right or left. It is back at the dealers now, they called FoMoCo who thinks it is the Pirelli tires.
Any thoughts?

Me too, dealership did check with digital guage. All within 2 lbs of specs, and were hot. They say they checked again the next morning then drove with cold tires, no change.
Checked alignment, all ok. I asked them to check rear suspension components, don't know if they did or not. They put a set of tires and wheels from an 05 on, supposedly solved the problem, but I haven't driven it yet. That is tomorrow.
Just wanted to see of others had this problem in the past.

What do they mean when they say within 2lbs of spec? Within 2lbs of max? Surely not. I can't run empty with tire pressures at max. What were the actual numbers? This is probably not it, but I am curious now.........

Sticker on drivers door jam calls for 60 psi front and 75 rear. Truck is at the dealer now, cannot read the sticker.

Well, oversteer of the magnitude you mention, can be from lots of reasons. New tires are really soft and slick untill heat cycled (hard to do on the street) a few times. Those reccomended tire pressure's you see are for maximum weight capacity, not for handling.
Also driver input, are you used to all that torque? Going into turns a little quicker with the new ride?

Had two other people drive it before I took it back to the dealer. One is a retired sheriff, spent 10 years underecover, drove a different car almost every day. Other is the owner of a front end and brake shop. Both felt there was something wrong.
So did the service manager of the dealership, although he wouldn't say so.
It's almost like the a$$ end swings out causing a sudden overstear. Starts into the curve fine, then all of a sudden it dives.

I had that exact same problem on the highway with my 02 when I put new tires and shocks on at the same time. Scarred the crap out of me when I hit the turns at my usual speed and felt the backend go around. Turned out to be the tires. It stopped doing it after around 200+ miles at highway speeds. I have the Rancho 9000 series on there and was able to adjust them to minimize the effect. Once the tires were "broke in" I was able to set the shocks at any position w/o a problem.

Dealer put on a set of B F Goodrich All Terrain tires and wheels off another F-250. Problem all gone. Turned out Ford had the same problem with Perelli's in 2005, dealer presumed that due to Ford's knowing about it in 2005 they wouldn't do that in 2006. Not.
5 new BFG's are being sought.

Just picked up my '06 F-250 Crew Cab SB PSD with the NEW BFG tires, completely different truck! Actually goes where you point it. Tracks like a Mustang, used to track like an empty boat trailer.
No charge for the BFG's even though they were a $250 upgrade on the MSRP.
Dealership will be getting Completely Satisfied on the Customer Satisfaction Survey. By the way, that is critical for any franchise dealer, it even controls the pricing on the vehicles it buys from the manufacturer and the allocation of popular vehicles.
