Shunt Malfunction Signs. If your child becomes very ill (persistent vomiting, extreme sleepiness, severe headache), seek medical assistance immediately. Call your childâs doctor if you think that your child is having a shunt malfunction based on the symptoms described above. Remember that you may see only one or two warning signs at a time.
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.
Another thing to note when getting new tires or checking your old is that all four tires will most likely not be the exact same age. On a previous set of tires I purchased, I found that three of my new tires were made in the second week of 2008, while the fourth was made in the 21st week.
