if you are using a azenis sport RT615, advans, s-03s, kumho mx or some similar tire that is temperature sensitive i'd wait until the overnight low temp is consistently above 40F for 3 weeks before switching over. it is scary/dangerous getting caught in the last snow of the year on aggressive tires

however, it seems that most guys here run really mild commuter tires in the summer such as falken 512, kumho spt, so really its just a matter of whether you are ok with the potholes or not
