When Is The Best Time To Buy Winter Tires

in Florida?

I have a set of snow tires that I’m going to be replacing this Spring. I live in south Florida, and the only time we ever get a chance to use them is when it snows (about once every 4 or 5 years). Are they completely useless during the other four months of the year?

The reason I ask is because my car’s original tires were bald after about 6 years; but they lasted almost 11 years on the winter tires. When was there last time you replaced your winter/snow-tires?
