An outboard orientation stripe is added to the tread surface, with an offset toward the outboard tire face.
All GM approved tires (Production, Service and Accessory) have a TPC (Tire Performance Criteria) code.
A replacement tire that lacks the original TPC code will not meet the performance characteristics of the original tire, even if it is the same brand, model and size.
