You have AWD, most likely it is the front differential doing its thing, my friends Mercedes makes terrible noises and needs to have more throttle at full lock too. Nature of the beasts!

No, I have had the car 3 yrs and all of the tires are the same....

get the brakes looked at. you could have a leak in a wheel and the fluid could create a surface that is easier to grab.

Maybe there are different size tires on the car.

you are going too fast and jamming the breaks too hard
