I have winter tires mounted on wheels with TPMS. I also have a floor jack and can swap my wheels/tires over in less than 30 min. with everything put away. If the weather looks good for about a week or more I will swap to the summer wheel/tires. That works well for me and saves my winter setup a little dry pavement wear.
