MADISON COUNTY, Ala. - There's never a good time to have car trouble, but having issues this time of year with these hot temperatures can be especially problematic. Before you hit the road, it might be good to check the air pressure in your tires.

"Tires generate heat and with the hot road surfaces it's very important to stay on top of your air pressure and ensure you have good tread conditions this time of year," said mechanic Chris Zimmerman.

Hot air expands, meaning your tires that were properly inflated a few months ago, may now be over inflated.

It's not just tires that can leave you stranded somewhere. "Any time you have a major fluctuation in temperature, whether it's hot or cold -- if a battery is nearing the end of its life, sometimes that will push it over the edge," Zimmerman added.

Of course, having a running car is pointless if you can't drive it. Experts say you need to take care of yourself by pre-hydrating before you drive away. "When we think about pre-hydrating before you go out in the heat, water is most likely the best," said Dr. Christopher Lillis of UC Davis Medical Center. "But to replace fluids you lose in the heat, it is good to have something with electrolytes. So the sports drinks are fine, but they do have a lot of sugar and additives. I've taken to recommending coconut water for my patients because of the high sodium and potassium and relatively low sugar."

Doctors also recommend always carrying water in your car in case of a breakdown.
