AMG GTR juddering at low speed

AMG GTR owner here, I just got my car not long ago. I was parking in an outdoor parking lot today (I am from Vancouver region). I noticed when I was turning at a sharp angle (almost locking my steering wheel), my car would judder and I felt I was also losing traction a bit (outside temp roughly 5 degree with rain). I was wondering if any of you guys experience the same thing? Should I take it to Mercedes-Benz to get it checked?

Thanks

It is the width of the tires man. You’ll get there in warmer weather as well - probably not as bad though. you are essentially dragging the tires across the pavement. Nothing you can do. Was like that on my GT350R as well.

100% normal. It's called the "Ackerman effect" - read about it here...

When it starts to occur, stop turning the wheel as sharp and do the turn in phases. You’ll get a feel for it.
It mostly occurs when the tires are cold so when they warm up you won’t experience it as much.

Agree with all posters...I get the same when car and tires are cold.

Are you still on summer tires?

Summer rubber gets stiff and slides in cold weather... perfectly normal... you should run all seasons in the winter or a set of winter tires if you plan on driving it in cold weather

This. My Giulia Quad is so loud that people in the vicinity think something is breaking. It's worse with sticky/R comp tires.

My front sensor is also super sensitive and it beeps like crazy when a car is approaching me (not even really close). Anyone has that issue?

Thanks
