Heat isn't easy on vehicle tires, and as the seasons change, make sure yours are ready to take the heat.
Let's talk first about inflation. Heat causes air to expand, so heat alone can raise the pressure in your tires. If you are driving on overinflated tires, they won't have as much contact with the road surface. In that case, it will take you a longer distance to stop.
On the other hand, you don't want your tires to be underinflated during hot weather, either. That can cause your sidewalls to flex. Friction will then hike up the temperature and your tire can be in danger of blowing from the added heat.
Other things can cause problems, such as uneven wearing. Your service advisor knows the signs to look for and can diagnose where the wear is and what is likely causing it. Another thing a technician will look for on tires is tread depth and the condition of the sidewalls. Any cuts, cracks or bulges could be indications that your tire is not healthy.
Oh, and one other thing. Your tires could have plenty of tread left on them but still be dangerous. And that is because rubber ages, gets brittle and cracks after time. (Ever run across an old rubber band in a drawer that has never been used but breaks the second you try to stretch it? 'Nuff said.) Some tire manufacturers recommend replacing tires after 6 years of their manufacturing date. Your service advisor can read a manufacturing code and tell you how old your tires are.
Tire manufacturer Michelin used to have an ad slogan that said, "Because so much is riding on your tires." That includes you and your passengers. Always keep healthy tires on your vehicle and make sure they're ready for whatever season it is.
