Can you fit 18 tire on 17 rim?

No, you cannot fit an 18-inch tire on a 17-inch rim. Tires are designed to fit specific rim sizes, and an 18-inch tire requires an 18-inch rim for proper installation and safety. Attempting to mount an 18-inch tire on a smaller rim could lead to damage to both the tire and the rim, as well as potential safety hazards while driving.
