Car wandering/pulling over uneven roads/bumps
 
would anyone care to let me know if this steering is normal.. i know the sport pkg ditches the active steering and is "heavy"... over smooth straight roads the car is fine.. no pull.. no allignemnt issues.. over the slightest bumps or uneveness the car follows them and pulls from side to side.. gotta fight the steering to keep it straight.. its not overwhelming but im just posting to find out if this is normal behaviour..????

i think the cause is related to wider tires this 'drift' from centre does happen. should be bad on roads heavily travelled by buses and trucks where there are ruts in the road.

true.. but i've never experienced this sort of tram-lining in other cars.. I test drove an audi S4 yesterday with similar width tyres and it was fine.. although the steering was hysterically loose and felt like you could steer the car by blowing at the wheel... I think the run-flats are partially to blame.. switching to non run-flats next summer..
