Though some trucks are equipped with P-Metric tires, certain manufacturers equip their vehicles with LT tires instead. They'll operate the same way merely may crave more inflation nether higher force per unit area than their P-Metric counterparts. If your code doesn't take a "P" at the beginning, it conforms to Euro metrics instead.
