By nature we all have 4 tires in our life. We must check them on a daily to know where we stand in our health, mental, spiritual and financial. If one is lacking air in a tire then your car will be out of balance and it will cause you to slow down in your life or cause an accident. It is very important to check ourselves where we stand so we don't harm ourselves or other around us. Make sure your car tires have the same psi so your life can move smooth and enjoy the ride peacefully.
