From the Super Mario Wiki
Blue Standard tires (known as Normal Blue in the British English version) are the palette-swapped counterpart of the Standard tires, except with chevron-shaped treads. They first appear in Mario Kart 8 and Mario Kart 8 Deluxe as an unlockable tire part. In the original Mario Kart 8, they share identical stats to the Standard, Off-Road, and Retro Off-Road tires; they are well-balanced with no strengths or weaknesses. In Mario Kart 8 Deluxe, Toad occasionally uses this tire whenever he is using the Sneeker.
