tire meets all federal standards. The next two numbers or letters are the plant code where it was
manufactured, and the last four numbers represent the week and year the tire was built. For example, the
numbers 3197 means the 31
st

manufacturer’s discretion. This information is used to contact customers if a tire defect requires a recall.

polyester, and others.

be carried by the tire.
Maximum Permissible Inflation Pressure
