Suck it up, they're making you strong.
Agree -- early spring is when studded tires are most valuable, because meltwater freezes overnight, and thin ice over pavement are where studs shine.
Rule of thumb would be the same for when you can put flowers out -- last freeze. Or just watch for tulips coming out of the ground, and change your tires when you see them bloom.
