Is it not useless to mobilize additional tire budget to buy winter tires?
The kilometers you will drive on winter tires are kilometers that your summer tires will save. Winter tires are usually of the same price if not lower than summer tires. Considering that you will need to buy at least one set of tires during the life of your vehicle, buying winter tires right from the beginning will represent the same money invested at the end, but you will benefit from a better performance in winter weather conditions and increased security.
