From the Super Mario Wiki
Blue Standard tires (known as Normal Blue in PAL regions) are the palette-swapped counterpart of the Standard tires, except with chevron-shaped treads. They first appear in Mario Kart 8 as an unlockable tire part. They share identical stats to the Standard, Off-Road, and Retro Off-Road tires; they are well-balanced with no strengths or weaknesses.
