In July, the asphalt on the valley floor gets far hotter than the air above it. Your tires sit on that surface and build their own heat from flexing as they roll. Put the two together and you have the main reason blowouts spike every summer.
The biggest risk isn't overinflation, it's underinflation. A tire that's low flexes more, and more flexing means more heat. Eventually the internal structure breaks down and the tire fails, often at highway speed.
The fix is simple: check your pressure once a month and before any long drive, with the tires cold, first thing in the morning before you've driven. Use the number on the sticker inside the driver's door, not the maximum printed on the tire sidewall. Don't forget the spare.
While you're down there, look for bulges, cracks, or cuts in the sidewall and uneven wear across the tread. If anything looks off, call us. A two-minute inspection in your driveway beats a two-hour wait on the shoulder.
