It's that time again

This is a blip, published every year for me to keep track of when I change tyres from summer to winter ones. As might see I don't use studs on my winter wheels because we rarely get those kinds of conditions here, when studs are needed. These wheels has a type of rubber that withstands cold temperature much better than the summer ones, they holds the grip better in winter, plus they have deeper patterns, designed to work good in snow. 
Being careful and to use ones experience is a useful addition to good tyres though.
