When seasons start to change and the temperature slowly starts to rise and get warmer, we start to prepare by doing things like putting away our winter coats. Seasonal tyre changes are no different, as you are helping your car stay prepared for changes in weather conditions.

Different temperatures can have different effects on your tyres which is why it’s important to be aware of these things. So you may be asking yourself, how does warmer weather affect my tyres? The truth is, warmer weather can have a surprising impact on tyre performance, safety, and lifespan. From changes in tyre pressure to an increased risk of a tyre blowout, warmer temperatures can affect your tyres and your vehicle’s road holding in subtle but important ways.

How Does Warmer Weather Affect My Tyres?

One of the biggest impacts hot weather has on your tyres is pressure. As the air temperature rises, the air within the tyre expands. This increase can inflate the tyre more than intended, particularly if it was already filled close to the recommended pressure.

The pressure of warm tyres will always be higher than that of cold tyres, and tyre pressure increases by around 1 psi for every 10°C rise in ambient temperature. This change might seem minor, but it’s enough to affect the way your tyres and vehicle perform, especially over longer journeys.

If the tyre pressure is too high, it can cause the tyres to expand, reducing the size of the contact patch with the road surface. That means less grip, uneven wear, and increased braking distances which is not ideal when the roads are dry and the traffic is heavy. On the flip side, if the pressure is too low, the increased resistance and friction causes a build-up of heat inside the tyre potentially which can lead to premature wear, or even worse as it can cause a tyre blowout.

Why It’s Vital to Check Your Tyre Pressure Regularly

Whether you’re planning a road trip or just driving to work, it’s essential to check your tyre pressure weekly during the warmer months. Don’t check when they’re hot to the touch and always check when the vehicle hasn’t been driven recently, so you’re getting an accurate read of cold tyre pressure.

If your vehicle has a built-in tyre pressure monitoring system, it will alert you if the pressure drops too low or climbs too high. But even if it does, it’s wise to check your tyres manually too. A good-quality tyre pressure gauge can help you keep your car tyres within the correct range.

As a general rule of thumb, the pressure will increase as heat builds. And because the weather can affect pressure so easily, it’s wise to adjust it according to the air temperature and road temperature combined.

How Heat Affects Your Overall Tyre Condition

Warm weather doesn’t just influence pressure as it also affects the rubber on tyres, their overall performance, and how long your tyres will last. In hot weather, tyres are subjected to road surface generating heat plus the heated air within. This combination accelerates wear, particularly if the tyres aren’t inflated correctly or the tyre tread is already low.

The build-up of heat inside car tyres is no small issue. It causes the rubber to soften, which can lead to faster degradation. The hotter the tyre, the higher the pressure, and the more strain placed on the sidewalls. Tyres that aren’t in good condition may even drop below the minimum tread depth faster due to this.

It’s important to keep your tyres clean and ensure they’re in good condition throughout the summer. Proper maintenance helps them remain safe and remain in good condition for longer. In addition, opting to switch out your tyres for summer tyres can help them last for longer and ensure that your vehicle is better prepared for any weather conditions.

How to Keep Your Tyres In Good Condition This Summer

To ensure your tyres are safe, check your tyre pressure regularly and especially before long drives. You should also look out for signs of uneven wear, bulges, or cracks, as heat can affect the way your tyres wear down over time.

If your tyre has been driven a lot in summer, or if the weather changes suddenly, it’s time for a check-up. It’s best to stop driving and let your tyres cool down if you notice wobbling, pulling, or unusual vibrations, which are all signs that pressure can make a big difference to your ride quality. Tyres cool slowly, so avoid measuring tire pressure (or tyre pressure) immediately after a journey. Let the air inside settle for accurate results.

Why Are Summer Tyres Recommended

The rubber compound in summer tyres is designed to provide optimal performance in warm conditions. They’re good at absorbing heat, resisting pressurised air build up better than other types, and deliver better traction and fuel economy on dry roads.

If you’re still driving on winter or all-season tyres, now’s the time to upgrade. Winter tyres are built for low temperatures and can crack, underperform, or wear rapidly in hot weather without changing to the appropriate type. Summer tyres offer the right balance for warmer weather and keep your vehicle safe on both urban and motorway journeys.

Not only does hot weather affect pressure and grip, but warmer weather conditions it can also impact how tyres and vehicle perform overall. Tyres that are poorly maintained or incorrectly inflated in warm conditions are more likely to underperform, wear unevenly, or fail altogether.

The health of your tyres affects how safe, comfortable, and economical your drive is. Whether it’s understanding how much air within the tyre expands, or knowing how to alter the air pressure, it’s all part of staying safe on the road. If you’re still considering whether summer tyres are worth it or perhaps looking into the benefits of all season tyres instead, and if you’re not sure where to begin, Mobile Tyres is here to help. Switching to summer tyres can be a useful step in being better prepared for the warmer weather but there are other options available and we can recommend the best tyres for your specific needs.
