What are some things i should know about driving in michigan winters? do i need winter tires? should i disable my abs?

Probably the best advice I've read in years.

Don't slam on the brakes, don't slam on the gas, don't change lanes quickly. Pay attention to other people and how they are driving, people tend to do dumb fucking shit like pull out in front of you while you're doing 50 and it's actively snowing.

You're also getting off lucky if you're in SE MI, we haven't had snow yet. West side of the state or northern half have had a little bit

Remember that EVERY aspect of your car is diminished. Acceleration, braking, traction, steering and so on.

Winter tires will help you in all aspects, but they do not make you invincible - the worlds best winter tires will still have less grip on snow than the worlds worst summer tires will have in summer. I dont know what Michigan winters are like so I can't say if you need winter tires, all seasons or if average summers are fine
