Acceleration squirm

Hi, I have noticed that my w203 squirms a lot when under acceleration. i've only had it a few months but have had no serious issues. i have replaced all 4 tires, and the alignment is perfect. i have also inflated the rear tires to about 3-5% psi under their recommended max. i do hear a slight squeak that is possibly the rose bush or something but would that really cause squirm under acceleration? when accelerating the car would squirm / fish tail slightly or rock. it stops as soon as i stop accelerating. any ideas what this could be, mechanics seem reluctant to investigate it. Thanks in advance

I sure hope you do not mean the max on the side of the tire. If so thats the problem.

sorry i didnt mean to add the '%' symbol. The max was 50psi and i inflated it to 45psi but the squirm remained.

the psi was originally 35psi and i read that increasing the psi should fix the squirm. this is why i inflated the tire to that.

This hasnt fixed the squirm so has anyone else had this problem or knows of how to fix?

again thanks in advance.

Can you possibly film the tachometer and the speedometer while the car does that?

Accelration squirm

Hi sorry for the delay in replying, i wasnt sure on how to upload videos.

I dont know what this will tell you about the squirm but here is a link to the video:

https://dl.dropboxusercontent.com/u/53888633/20160808_182318.mp4

The entire time the car is accelerating there was squirm. Also i notice that the squirm is constant at higher speeds of 60+ mph and only goes away when i remove my foot from the accelerator (ie holding a high but constant speed and goes away when i begin to slow down).

I'm not sure if this is related but going around round-abouts and sharp corners, no matter how safely, the car will begin to slide. i have to resort to going extremely slow to prevent it from happening to the annoyance to other drivers!

could this all be a differential problem?, i don't hear any noises that suggests it might be.
