My 2014 FX4 accelerates smoothly and decelerates smoothly, but at a steady speed feels like I'm driving over a washboard, stuttering almost like a cylinder is out. Light vibration. I've tested on newly laid tarmac so it's nothing to do do with the road surface.

My local Ford tech said it was probably due to the 20" Pirelli Scorpions and said it was normal.

It's driving me mad. Any thoughts as to the problem ?

Well Pirelli Scorpions are known to be less than ideal. Google it, those tires flat out suck.

 

Do you buy chance have anything built up in the rims from snow or 4x4ing?

 

Yeah. Heard that quite a few times on this forum from users and dealerships alike.

 

Thanks for info so far. Rims are clean, it has done this since new.

I have it leased only until November so can't experiment with tires. It's my 4th F150, the second with Pirelli's, but the only one with this vibration.

It's distracting and spoils the ride. Any more ideas would be appreciated.
