P-Metric Sized Tires
Most P-metric tires do not have exact corresponding alpha-numeric tire sizes. For example, a P205/75R15 is not equal in size and load carrying capacity to an FR78-15. For this reason, replacement tires should be of the same TPC specification number (size, load range, construction) as those originally on the vehicle. If P-metric tires must be replaced with other sizes, a tire dealer should be consulted. Tire companies can tees recommend the closest match.
