It really depends.
For most of my life I've been a one-bike rider. Sometime I rode the same tires year-around. Others I swapped tires.

I now have a dedicated "winter bike" which I thought I'd try installing some Tannus solid tires on. The tires are a bit of a pain to install... so it is once on the rims... until they're worn out. The bike gets a little summer use, but most of the riding is in the winter.
