Winter tires should be installed when you expect temperatures to fall to 7 C or below. As the temperature falls, the rubber in summer and all-season tires becomes hard and inflexible, killing traction. Auto insurance companies now give you a discount if you have winter tires, so call Marken Performance @ 519-893-4383 or 1-888-401-1362 and arrange to get your winter tires installed now. We have 4 different ones to choose from. If you need winter rims, Marken Performance can also help you. Winter tires should also be narrower than summer tires for maximum traction (if you car came with 215-millimetre wide summer tires, for example, your winter tires should be 205 mm or 195 mm).
