Let's take a look. Remove snow tires. While snow tires work great in the winter, they're not much good in the summer months when there's no snow on the ground. Plus, you'll wear them out much faster by using them on dry pavement. Check the tire pressure.
Tire pressure is important at all times.
It's critical to have properly inflated tires, as this assures the best possible contact between the tire and the road. Properly inflated tires will also last longer and improve gas mileage. Because of summertime's higher temperatures, the air pressure in a warm tire rises. Because air is a gas, and gas expands when it heats up. Keep this in mind if you are checking tire pressures.
