Car Tyre Pressure in the Winter vs Summer: All You Need to Know

Key Takeaways

• Tyre pressure decreases by 1–2 PSI for every 10°C drop in temperature during winter months, requiring more frequent monitoring and adjustment to maintain safety and performance.
• Summer heat causes air expansion in tyres, potentially leading to overinflation which reduces road contact, decreases traction, and causes uneven wear patterns.
• Regular tyre pressure checks (every two weeks) are essential, especially during seasonal transitions when temperature fluctuations are most significant.
• Properly inflated tyres improve fuel efficiency, reduce CO2 emissions, extend tyre life, and enhance safety through optimal road grip in all weather conditions.
• Ordiniq's AutoPump is a well-rounded solution for year-round tyre maintenance with its 150 PSI performance and smart auto shut-off technology. 

Temperature Effects on Tyre Pressure

Driving requires maintaining the right tyre pressure so that you stay safe and your vehicle healthy. But changes in temperature can change the pressure and, if left unchecked, damage your tyres. That’s why every driver should know how and when these changes happen so they can get them adjusted as soon as possible.

Winter Pressure Drop

During the winter months, tyre pressure decreases; for every 10°C drop in temperature, tyre pressure can fall by 1 to 2 PSI. This might not sound like much, but it can significantly affect your vehicle's handling, safety, and efficiency.

Imagine you're driving on a snowy road with underinflated tyres. The lower pressure means more of the tyre's surface area contacts the road, increasing friction and making it harder to steer and stop. This can be particularly dangerous in icy conditions where precise handling is crucial.

That’s why you should monitor your tyre pressure more frequently during the winter. Check your tyres every two weeks to make sure that they’re at the correct pressure for your vehicle.

Summer Pressure Increase

On the flip side, tyre pressure tends to increase in the summer. As the temperature rises, the air inside the tyre expands, which can lead to overinflation.

Summer: Monitor for Overinflation

Keeping an eye on tyre pressure during the warmer months is just as crucial as in the winter.

Tyre overinflation in the summer can reduce how much a tyre comes in contact with the road, which can worsen its grip and potentially cause uneven tyre wear.

Overinflated tyres can also affect your vehicle's braking distance and handling, especially in wet conditions. Imagine driving on a rainy day with tyres that have less grip on the road; with less grip, your car is now more prone to hydroplaning, and you could get in an accident. Regular checks are just as vital in the summer to make sure your tyres are properly inflated.

Adjusting Pressure Accurately

Ensuring your tyres are at the correct pressure keeps your vehicle safe and efficient. Properly inflated tyres provide better fuel economy, saving you money at the pump and reducing your carbon footprint.

Using a Reliable Gauge

When choosing a tyre pressure gauge, look for one that’s accurate and easy to read. Digital gauges are often more precise than their analog counterparts, and many come with features like backlit displays for easy reading in low light conditions. 

Checking your tyre pressure is straightforward. Just follow these steps:

1. Remove the valve cap,
2. Press the gauge onto the valve stem, and
3. Read the pressure. 

Compare the reading on the gauge to the recommended pressure listed in your vehicle's manual or on the sticker inside the driver’s door. Adjust the pressure as necessary by either adding or releasing air.

Following the Manufacturer's Recommendations

Your vehicle's manufacturer determines the optimal tyre pressure for your car based on extensive testing. This pressure ensures the best balance of comfort, safety, and efficiency. It's vital to adhere to the recommended pressure since manufacturers consider the specific weight and handling of your vehicle.

Altitude Considerations

Impact on Tyre Pressure

For every 1,000-foot increase in altitude, tyre pressure can rise by approximately 0.5 PSI. While this might not seem like much, pressure can build up quickly if you're driving to a high-altitude destination. If your tyres become overinflated, they might affect your own safety and comfort during your trip.

Best Practices for High Elevations

To manage tyre pressure effectively at high altitudes, consider the following:

• Check tyre pressure before and after significant altitude changes.
• Carry a portable air compressor to adjust pressure on the go.
• Be aware of the signs of overinflation, such as a rough ride or lower traction.

Seasonal Impact

Balancing Safety and Efficiency

When tyres are inflated to the right levels, they provide optimal traction for a safe ride. Proper inflation ensures that your tyres wear evenly which extends their lifespan and saves you money in the long run.

For instance, a study from the US National Highway Traffic Safety Administration found that vehicles with underinflated tyres are three times more likely to be involved in a crash.

Frequently Asked Questions (FAQ)

How often should I check tyre pressure in the winter?

In winter it's recommended to check your tyre pressure every two weeks. Cold temperatures can cause the air inside your tyres to contract, leading to a drop in pressure. Regular checks help ensure your tyres are properly inflated and safe for winter driving.

Is it normal for tyre pressure to drop when it's cold?

Yes, it's completely normal—as temperatures decrease, the air inside the tyres contracts, resulting in lower pressure. That’s why it's vital to monitor and adjust your tyre pressure more frequently during the winter months.

How can I find the right tyre pressure for my car?

The recommended tyre pressure for your car can usually be found in the vehicle's owner's manual or on a sticker inside the driver's door. This pressure is determined by the manufacturer for optimal performance and safety. 

Do changes in altitude affect my tyre pressure?

Yes, altitude changes can affect tyre pressure. As you go up in altitude, atmospheric pressure decreases, which can cause your tyres to expand and increase in pressure. 

Why should I consider Ordiniq for tyre maintenance?

Our products like the AutoPump help you monitor and maintain the correct tyre pressure so that you stay safe on the road. With Ordiniq, you can trust that your vehicle is in expert hands.
