today, i was exiting the freeway to go home. the exit consists of a nice right followed by a left. i normally take this exit pretty fast to get around the slower cars. today, when i took the left, my car did something really weird. it locked up as if the VDC kicked in and made a sound that i can only describe as a groaning you would hear on a giant ship. the slip light never came on. so far, my car has done this only 1 time before when i was taking a right off another freeway exit.

anyone have any ideas what it could be?
would it possibly be due to the fact that I have 245/45/17 on the rear and 215/50/17 on the front?
