What Happens To Tire Pressure In Hot Weather

Your car’s tires are up against an often-overlooked challenge as the sweltering summer sun beats down on the pavement. It is the effect of high temperature on tire pressure. Maintaining your vehicle tire pressures is essential not only for your safety but also for the longevity of your tires and your vehicle’s fuel efficiency.

What Is Tire Pressure?

It refers to the amount of air inside your tire, measured in pounds per square inch (PSI). It’s the air in the tires that supports the weight of your car, not the tires. Besides, it’s typically maintained at 32 PSI and less.  The right tire pressure is essential for your vehicle because it affects how well it accelerates or brakes. Your safety while driving may be compromised by under- or over-inflated tires.

How Hot Weather Affects Your Tire?

Due to the physical properties of air and rubber hot weather can have a considerable effect on your tire pressure. When the temperature rises the air starts to expand inside your tire. The air molecules move more quickly as a result of this expansion, which raises tire pressure. As a result, for every 10 degrees Fahrenheit rise in temperature, the tire pressure may increase by approximately 1-2 PSI.

How To Maintain Vehicle’s Tire Pressure In Hot Weather

Regular Check-Ups

For your safety, you must establish the practice of checking your car’s tire pressure at least once a month, especially before long trips. At last, a trustworthy tire pressure gauge should be used to ensure accurate readings. An old tire pressure gauge may result in incorrect readings.

Check The Pressure Of The Tire

When the tire is cold, it is the best time to check the pressure. Since the tires heat up while you’re driving, the interior air may expand, which will primarily result in inaccurate readings. Therefore, try to check your car’s tire pressure before you start driving in the morning and a few hours later.

Adjustment For Temperature

Temperature and weather impact the tire pressure, and always remember that as the temperature rises, tire pressure rises as well. Tire pressure can rise by about 1-2 PSI for every 10 degrees Fahrenheit rise in temperature. To compensate for this during the warmer months, keep the tire pressure 1 to 2 PSI lower than the actual pressure required.

Balance Load And Pressure

This is crucial because carrying an extra load on your vehicle without adjusting tire pressure can result in excessive wear and compromised handling. If you’re planning to travel with extra luggage or carry extra passengers, you should consult your vehicle’s manual for instructions on adjusting tire pressure to accommodate extra load.

Avoid Over-Inflation

Avoid overinflating your tires to prevent temperature-related pressure changes. They can cause an uncomfortable ride, decreased traction, and uneven wear. Always adhere to the manufacturer’s recommended pressure.

How TPMS Helps Maintain Tire Pressure?

Since the heat can cause the tire pressure to rise, the tire pressure sensors monitor and detect any unusual pressure or temperature rise. Therefore, consider buying the TPMS sensors best suited to your vehicle.
