Race tires will have no such branding but the cheater style tires may have DOT or similar branding but are essentially race tires with lighter all-round construction, minimal tread grooves etc. and not realistically street legal. Similarly the UTQG labeling ( Treadwear, Traction, Temperature ) give an indication of similar performance of like branded tires , but given that all manufacturers use different combinations of products to produce their tyres and perform their own controlled testing and branding then not all similarly branded tyres will perform the same.
The point I’m trying to make is that if you ask 5 different “ tire experts “ the same question then you are likely to get 5 different answers and possibly not any of them are wrong.
