Can I leave my winter tires on all year ?
Q: Can I leave my snow tires on all year?
A: You can, but it's not a good idea. Snow tires tend to be noisier, get lower gas mileage, plus the softer compounds from which they are made means they will wear out faster, especially in warm weather. Wear is critical, because winter tires rely on their deep tread to dig into snow and ice. As soon as the snow is gone for good, remove your snow tires and re-install your regular tires
Studded winter tires have to be off by May 1st in the State of Maine.
