Vehicle
2011 BMW X3 (x35i)

Symptom

The car drives fine however when there is some imperfection in the road (crack, bump, new-old asphalt divider) and the tire hits it the vehicle tends to take off to the right a tad aggressive for my taste. Now i can bring the steering wheel back to centre and it sometimes keeps the position driving the car perfectly straight but other times it will slowly drift right if i dont position the the steering wheel just right.

Do i have an alignment issue, tie rod issue, or some other problem? Or is this normal for these tires?

Note:
Tire Size **edited**
Front Wheels: Pirelli PZero RUN FLAT 245/40R20 RSC tires (tire pressure 32psi)
Rear Wheels: Goodyear Eagle F1 Run On Flat 275/35R20 (tire pressure: 38psi)

Maybe your tires aren't right size.
OEM staggered for 20" is
F 245 x 45 x 20
R 275 x 35 x 20

if square setup : 245 x 40 x 20

yours is different

Plus different rubber pattern front vs rear (not sure if this would really affect pull)

Thx for response doru.

I erred. The tire size is actually:

Front Wheels: Pirelli PZero RUN FLAT 245/40R20 RSC tires (tire pressure 32psi)
Rear Wheels: Goodyear Eagle F1 Run On Flat 275/35R20 (tire pressure: 38psi)

I will update the post
