You know the drill. Winter arrives. Temperatures drop. A warning light appears on your dashboard. You check your tire pressure, and sure enough, all four tires are low. You add air, and the light goes off. You feel responsible. You understand that cold weather reduces tire pressure.
Then summer comes. The sun blazes. The pavement shimmers with heat. You assume the opposite must be true. Heat expands air, so your tire pressure must be fine. Maybe even too high. You do not check. You do not think about it.
That assumption is a dangerous myth.
Hot weather does not automatically keep your tires properly inflated. In fact, summer driving creates unique tire pressure challenges that can be just as dangerous as winter under-inflation. Ignoring your tires in the summer is not saving you time. It is putting you at risk.
Here is why you need to check your tire pressure in hot weather too, and why the "summer air" myth could leave you stranded or worse.
