Check Your Tires
Tires are one of the most overlooked parts of a car. According the Rubber Manufacturers Association (RMA), only one out of 10 drivers checks his or her tire pressure correctly, compared with almost seven out of 10 who wash their cars regularly [source: RMA]. But the truth is that an under-inflated, over-inflated, worn down or misaligned tire can be extremely dangerous, particularly in hot summer weather.
