Default car pulls to the side under sudden weight shift

Recently i've noticed that when accelerating my car will pull to the left. When lifting off the throttle it will quite noticeably pull to the right.

tire pressure is fine all around. i thought it was the wind but its definitely not that. might this be an alignment issue or is this indicative of something more serious like too much chassis flex?

any suggestions of things to check out myself to narrow down my problem?

alignment and tire pressure are your major culprits here. have you smacked anything recently that would have knocked the alignment off? is the car lowered or is there uneven wear on any of the tires?

i live in a region with terrible roads, seriously awful.

recently after a flat i noticed some uneven wear on the tire so perhaps your right but the pulling feels particularly dramatic under weight shift.

thanks for the input.

Even if you checked the tire pressure yesterday...go check it again now...even if you are 100% absolutely sure that your tire pressure is fine, go check it again now. 90% of these issues are related to tire pressure...even just a few psi difference from right to left can cause an s2k to jerk around like you describe.

Same thing happens to me, same tire pressure, but different wear, I have a brand new tire on my driver side rear rim, and a bald one with bands and chunks missing on my passanger side rear... My brand new tire on my pass. side tire leaked, went flat then it froze that way, filled it up and it was nothing but bubbles around the inside of the tire so I through an old rim and tire on lol ... Just in case any1 was wondering
