Tire pressure decreases quite rapidly with cold temperature. For every 10 degrees Fahrenheit the temperature drops, your tires drop 1 PSI.
Having an adequate amount of tire pressure is important year- round. If it runs too low in the winter, you’re putting yourself in immense danger.
You need proper air pressure to keep you safe. Winter tires have specific features to combat low temperatures, such as tread rubber and depth and biting edges.
Their tread is much deeper than a regular tire, and once it gets cold, their rubber expands and stiffens. You have a much better grip on the road, as the tread will expel snow and ice. Their biting edges add further protection by adding greater traction.
Keep in mind that both personal and commercial auto poli- cies can’t protect against a lot of accidents. Precautionary steps, such as investing in winter tires, minimizes your risk for injury.
