Heat increases tire pressure, which can worsen any existing tire problems. For every 10-degree rise in temperature, tire pressure can increase by about 1 PSI. This excess pressure, combined with road heat, can lead to blowouts, especially if your tires are already worn or have dry rot. Regular tire checks, including pressure and sidewall inspections, can help prevent these issues. In summer, it’s a good idea to check your tire pressure more frequently and consider a tire rotation to ensure even wear.
