Drive up and down frequently. M+S tires with AWD + some experience in ice and snow is perfectly sufficient for almost all road restrictions (other than the road being closed).
There are indeed checkpoints for restrictions but they won't actually pull you if you give them the thumbs up unless you have like a Lamborghini or something.
I would highly recommend shifting around your schedule to avoid snow over Donner Pass. Chains or no chains, it's dangerous and a lot of people lie about their cars and slide all over the place making it even more dangerous.
