You might want a helper to step on the brakes while you check your brake lights. The key may need to be turned on, on some vehicles to do this. Remember to check high and low headlight beams. Checking the tires is not only a safety issue but it can save you a lot of money as well. Start with tire pressure.
Most people have their own opinion as to what tire pressure to run and that is usually to high.
The pressure indicated on the side wall of a tire is the maximum pressure at maximum load. If you run this pressure with out a load, you will not only wear the tires out early, you will also degrade the ride quality. There are a lot of variables to tire pressure such as tire size, rim width and vehicle weight. One of the best ways to get the correct pressure is to draw a chalk line across the tread and drive a block or less and see if it wears off evenly at the center or edges. If at the center there is too much pressure and the edges not enough.
