Shunt Malfunction Signs. If your child becomes very ill (persistent vomiting, extreme sleepiness, severe headache), seek medical assistance immediately.

Replace the tires at least every 6 years. If you're not sure, the minimum replacement time that is recommended by the NHTSA is six years regardless of use, with 10 years being the maximum service life for tires. Check your owner's manual for specific recommendations related to your car.
This way, each tires experiences a variety of wear patterns over time, and wears out at the same rate as the other tires. Your car's owner's manual should tell you how frequently tire rotation is recommended. Schedules range from every 3,000 to 7,000 miles. As a rough estimate, rotating your tires every other time you change your oil should keep them wearing evenly.
