The external temperature has a significant impact on the tire pressure. As the temperature changes, the air inside the tire expands or contracts, affecting the overall pressure. In cold weather, the tire pressure tends to decrease, while in hot weather, it increases. It is important to note that the air inside the tire expands by about 1 psi (pound per square inch) for every 10°F increase in temperature.
Driving Conditions
Different driving conditions can also affect tire pressure. For example, driving on rough or uneven terrain can cause the tire pressure to decrease faster than normal. On the other hand, frequent driving at high speeds can increase the tire pressure. It is crucial to keep track of these factors and adjust the tire pressure accordingly to maintain optimal performance.
Tire Age
Tire age is another factor that can affect tire pressure. Over time, tires can develop leaks or become less airtight, leading to gradual pressure loss. It is recommended to regularly inspect the tires for any signs of aging, such as cracks or bulges, and replace them if necessary. Older tires may also require more frequent pressure checks to ensure safety on the road.
Tire Type
Different tire types have different pressure requirements. For instance, performance tires often require higher pressure for better handling and responsiveness, while all-terrain tires may have lower pressure guidelines to enhance grip and comfort. It is important to refer to the tire manufacturer’s recommendations for the specific tire type being used in order to maintain the correct pressure.
Importance of Proper Tire Pressure
Safety
Maintaining proper tire pressure is crucial for safe driving. Underinflated tires can lead to decreased maneuverability, longer braking distances, and an increased risk of tire failure.

Monthly checks provide a good baseline for maintaining proper tire pressure. Set a specific date each month to inspect the tire pressure and make any necessary adjustments. This routine practice can help identify any slow leaks or changes in pressure caused by external factors.
Seasonal Changes
Seasonal changes can have a significant impact on tire pressure. As mentioned earlier, colder temperatures cause the tire pressure to drop, while hotter temperatures cause it to rise. Therefore, it is advisable to check the tire pressure more frequently during extreme weather seasons, such as winter and summer, to ensure optimal performance and safety.
Before Long Trips
Before embarking on a long trip, it is vital to check the tire pressure to avoid any unforeseen issues on the road. Long trips can place additional stress on the tires, and the increase in temperature due to extended driving can affect tire pressure. Performing a tire pressure check before long trips can help prevent any potential problems and ensure a smooth and safe journey.
Signs of Low Tire Pressure
Change in Handling
One of the first signs of low tire pressure is a change in the vehicle’s handling. Underinflated tires can cause the vehicle to feel sluggish or unresponsive during acceleration or cornering. If you notice a significant change in how your vehicle handles, it may be an indication of low tire pressure.
Warning Light
Most modern vehicles are equipped with a tire pressure monitoring system (TPMS) that alerts you when the tire pressure is low. If the TPMS warning light illuminates on your dashboard, it is important to check the tire pressure as soon as possible and inflate the tires to the recommended level.
Visual Inspection
Performing a visual inspection of the tires can also help identify low tire pressure. Look for any noticeable changes in the tire’s shape or bulges, which may indicate significant pressure loss. Additionally, examine the tread wear patterns as uneven wear can be a sign of improper tire pressure.
Checking Tire Pressure
Tire Pressure Gauge
To check the tire pressure accurately, you will need a tire pressure gauge. There are various types of gauges available, including digital gauges and pencil gauges. Regardless of the type, it is essential to choose a reliable and accurate gauge to ensure precise readings.
Best Time to Check
The ideal time to check the tire pressure is when the tires are cold. Cold tires refer to tires that have not been driven for at least three hours or have traveled less than a mile at low speed. When the tires are cold, they provide a more accurate reading of the actual tire pressure.
Proper Technique
To check the tire pressure, remove the valve cap and firmly press the gauge onto the valve stem. Ensure a tight seal and wait for the gauge to provide a reading. Repeat the process for each tire and note the readings. If the pressure is below the recommended level, add air until the proper pressure is reached.
