Summer can be killer on your car for many reasons.  So keep your vehicle in top condition with these quick and easy summer car tips from AUTOBUY! The extreme heat on the road causes the air in your tires to expand, so it is important to check the pressure prior to heading out, when they are cool. Adequate pressure should be based on the recommendations for your vehicle (check owner’s manual or the label on the car door jamb) rather than that listed on the tire’s sidewall. This will help you avoid heat-induced blowouts.
