With UK temperatures now regularly reaching 30°C or more during summer heatwaves, many motorists begin to wonder whether the hot weather could damage their tyres or whether they should adjust their tyre pressures.
The good news is that modern tyres are designed to cope with warmer conditions. However, incorrect tyre pressures, poor maintenance and carrying extra holiday luggage can all affect tyre performance, fuel economy and lifespan.
To separate fact from fiction, we spoke to Joe Brammer, CES Technical Manager at Michelin, who explained how hot weather affects tyre pressure, tyre wear, fuel economy and overall tyre performance.
Does hot weather increase tyre pressure?
Yes. As temperatures rise, the air inside your tyres expands, causing tyre pressures to increase naturally. Tyres also generate heat while driving, which further raises the pressure.
Joe Brammer says this is completely normal.
"Tyre pressure naturally rises as the air inside the tyre heats up, particularly when being driven on, and in most cases this is normal. It is estimated that for every 10°C change in temperature, tyre pressure can change by 1–2psi."
While drivers may notice slightly higher tyre pressures during a UK heatwave, Michelin says there's no need to let air out simply because the weather is warmer.
Instead, he advises checking tyre pressures regularly throughout the year.
"Regardless of the weather conditions, Michelin's recommendation is that drivers should check their tyre pressures at least once a month (or before a long journey) and set them to their vehicle manufacturer's specification depending on the load of the vehicle."
Importantly, tyre pressures should always be checked when the tyres are cold, not immediately after driving, as warm tyres will naturally display higher readings.
Heading off on holiday? Check your tyre pressures first
Summer often means road trips, family holidays and longer journeys, which usually involve carrying far more weight than usual.
Extra passengers, luggage, roof boxes and bike racks all place additional load on the vehicle, meaning tyre pressures may need adjusting.
Brammer explains:
"This is important for drivers who will be travelling with a car full of passengers, luggage and in some cases a roof box/bike rack to their holiday destination. Often this load is greater than what is normally carried in the car and therefore the tyre inflation pressures should be adjusted accordingly to their vehicle manufacturers suggested laden pressures."
Checking your vehicle handbook or the tyre information sticker inside the driver's door will tell you the correct pressures for both normal and fully laden driving.
How do summer tyres perform in hot weather?
Despite the name, summer tyres aren't just designed for sunshine. they're engineered specifically to perform in warmer temperatures.
According to the Michelin tyre expert, the rubber compound remains stable in higher temperatures, helping deliver strong grip and predictable handling.
"Summer tyres are specifically engineered to perform in warmer conditions. Their rubber compounds are designed to remain stable and deliver strong levels of grip on both dry and wet roads during higher temperatures, helping to optimise steering precision, handling and braking performance."
That means motorists can continue to enjoy strong performance during periods of hot weather, provided their tyres are properly maintained.
As Brammer adds:
"In hot UK weather, a summer tyre should continue to perform effectively provided it is correctly inflated for the load that is being carried and has sufficient tread depth above the legal limit of 1.6mm."
Does hot weather wear tyres out faster?
Many drivers assume that prolonged exposure to high temperatures dramatically shortens tyre life, but Michelin says the weather itself is rarely the biggest factor.
Instead, how you maintain your tyres (and how you drive) has a much greater influence on how long they last.
Brammer explains:
"The greatest contributors to accelerated tyre wear are incorrect tyre pressures, harsh acceleration and braking, overloading the vehicle, poor wheel alignment and inadequate tyre maintenance."
He adds that when tyres are looked after properly, periods of hot weather should have very little effect on their lifespan.
"When tyres are correctly maintained and operated within their intended limits, periods of hot weather are unlikely to have a significant impact on their overall lifespan."
Can incorrect tyre pressure affect fuel economy and EV range?
Absolutely.
Whether you drive a petrol, diesel, hybrid or electric vehicle, incorrect tyre pressures can have a noticeable impact on efficiency.
According to Brammer:
"Underinflated tyres increase rolling resistance which in turn increases fuel consumption or reduce battery range and can reduce the contact patch with the road which leads to reduced grip."
He also points out that underinflated tyres wear differently from correctly inflated ones.
"A tyre that has been driven on underinflated may start to show signs of accelerated wear on the shoulders of the tyre. It is estimated that running a tyre 20% underinflated can reduce its lifespan by up to 20%."
Overinflation brings its own problems.
"In contrast to this, an overinflated tyre is more susceptible to impact damage and can start to display accelerated wear through the centre of the tread. Incorrect tyre pressure also compromises handling and braking performance."
For the best balance of safety, efficiency and tyre life, Michelin recommends checking tyre pressures only when the tyres are cold and always setting them to the vehicle manufacturer's recommended pressures.

Hot Weather Doesn't Damage Tyres – Poor Maintenance Does
While it's normal for tyre pressures to increase during periods of hot weather, Michelin's advice is clear: drivers shouldn't worry about the heat itself. Instead, the focus should be on regular tyre maintenance.
As Brammer concludes:
"Generally speaking, Summer tyres (and in most cases All-Season tyres too) are designed to perform in high temperatures but the important message is for drivers to perform regular maintenance checks of their tyres to ensure they are inflated correctly, free from damage and above the legal tread depth limit. Providing tyres are maintained, then the hot weather shouldn't pose too much of a problem."
For motorists planning summer road trips or everyday commuting, taking just a few minutes to check tyre pressures when they're cold, inspecting tyres for signs of damage and ensuring there's plenty of tread remaining can improve safety, maximise tyre life and even help reduce fuel consumption or extend EV driving range.

Frequently Asked Questions
Can tyres burst in hot weather?
Hot weather alone is very unlikely to cause a tyre to burst. Modern tyres are engineered to withstand high temperatures and are tested in conditions far hotter than a typical UK summer.
However, if a tyre is already underinflated, overloaded, damaged or has suffered an impact from a pothole or kerb, the additional heat generated during driving can place extra stress on it. Regularly checking your tyre pressures, inspecting tyres for signs of damage and avoiding overloading your vehicle are the best ways to reduce the risk of a blowout during a heatwave.
Is it safe to drive during a UK heatwave?
Yes. Modern summer tyres—and most premium all-season tyres—are specifically designed to perform in warm temperatures. As long as your tyres are correctly inflated, have sufficient tread depth and are free from damage, driving during a UK heatwave should not present any additional problems. Before setting off on longer journeys, it's always worth checking tyre pressures and ensuring your vehicle isn't overloaded with passengers or luggage.
What is the correct tyre pressure in hot weather?
The recommended tyre pressure doesn't change simply because the weather is warmer. Your tyres should always be inflated to the pressure specified by your vehicle manufacturer, and pressures should be checked when the tyres are cold. While tyre pressures naturally rise as the tyres heat up during driving, this is completely normal and isn't a reason to let air out of the tyres.
Why does my tyre pressure warning light come on in hot weather?
A tyre pressure warning light isn't usually triggered by hot weather itself. Instead, it indicates that one or more tyres are outside the pressure range expected by your vehicle's Tyre Pressure Monitoring System (TPMS).
If the warning light comes on, check your tyre pressures when the tyres are cold and inspect each tyre for damage or punctures. If the warning light remains on after correcting the pressures, the TPMS may need resetting or inspecting.
Can hot roads damage tyres?
Road surfaces can become significantly hotter than the surrounding air, particularly on dark tarmac during sunny weather. However, quality tyres are designed to cope with these conditions. Hot roads alone are unlikely to damage healthy tyres, but they can increase the effects of existing issues such as underinflation, overloading or worn tread. Keeping your tyres correctly inflated and well maintained is the best way to minimise unnecessary wear.
Should I check my tyres before a summer road trip?
Absolutely. Before setting off on a long summer journey, it's worth checking your tyre pressures, tread depth and the overall condition of your tyres. If you're travelling with extra passengers, luggage, roof boxes or bike racks, remember that your vehicle may require higher tyre pressures to safely carry the additional load. You'll find the correct laden pressures in your vehicle handbook or on the information sticker inside the driver's door.
Can hot weather reduce my electric vehicle's driving range?
Hot weather itself is unlikely to have a major impact on your EV's driving range, but incorrectly inflated tyres certainly can. Underinflated tyres increase rolling resistance, meaning the motor has to work harder and uses more energy. Keeping your tyres inflated to the manufacturer's recommended pressures is one of the simplest ways to maximise efficiency and battery range during summer driving.
What happens if my tyres are overinflated in hot weather?
Overinflated tyres are more susceptible to impact damage from potholes and kerbs, while also wearing more quickly through the centre of the tread. They can also compromise handling and braking performance by reducing the tyre's contact with the road. Always check tyre pressures when the tyres are cold and inflate them only to the pressures recommended by your vehicle manufacturer.
Are all-season tyres suitable for hot weather?
Yes. Premium all-season tyres are designed to provide dependable performance throughout the year, including during warm summer weather. While dedicated summer tyres remain the best choice for prolonged warm conditions and maximum performance, high-quality all-season tyres offer an excellent balance of dry grip, wet-weather performance and winter capability, making them a popular option for many UK drivers.
How hot do tyres get in summer?
Even on a warm summer's day, tyres can become much hotter than the surrounding air because they generate heat as they flex and roll against the road surface. It's perfectly normal for tyre temperatures and pressures to increase during driving, particularly on long motorway journeys. This is why tyre pressures should always be checked before driving, when the tyres are cold, rather than immediately after a journey.
