Having the correct tire pressure is an important part of regular maintenance of your car, and it's also a necessity for being a good driver. The amount of air pressure in your tires has an immediate effect on the quality of your driving, especially when braking and turning. Aside from these concerns, seasonal temperature changes can also effect the performance of your tires, and the overall pressure within them.
Let's start with the basics, of tire pressure.
Like most maintenance suggestions and requirements, always check the user manual and manufacturer's schedule for when to have certain repairs and what is required. Your car's user manual and maintenance handbook will also tell you the exact psi requirements for your tires, and you can also find this information on the tires themselves.
Always check the psi in your tires regularly, during scheduled maintenance and tune-ups (your mechanic should always do this for you), and it's a good idea to go it before going on long car trips too. If your tires are under-inflated, or have a low psi, this can create unnecessary drag on the car and can cause decreased fuel efficiency.
How does weather affect my tires?
When the seasons change and temperatures begin to rise and fall, so does the air pressure in your tires. Because air that is colder contracts, the air pressure inside your tires falls and the tire may become under inflated. In the summer, the reverse is true. When air starts to get warmer, the volume of the air expands, so for air trapped inside the tires, it begins to expand and increases the overall pressure and potentially causing the tire to become over inflated.
In extreme cases, this can damage the tires and cars if not taken care of. It's always a good idea to keep an eye on your tires and check the pressure when the temperature starts to rise and fall dramatically like in summer and winter.
Winter tires, tires designed especially to deal with winter weather precipitation like snow and ice, may have their own specific psi requirements that differ from the average tire. Be sure to check these when getting new winter tires, and check regularly to make sure that the correct psi is maintained throughout the season to deal with fluctuating weather and temperatures. This is especially important when driving in adverse weather conditions, so you always want to make sure you are fully prepared to drive in anything!
