jantlar

Jantlar are the circular metal components that form the outer edge of a wheel and provide the seating surface for tires. In Turkish usage, jant denotes the rim itself, and jantlar is the plural. Jantlar are used on bicycles, motorcycles, cars, and trucks, and are the part of the wheel that tires mount to and that interfaces with the hub and spokes in various wheel designs.

Construction and materials commonly seen in jantlar include steel and aluminum alloy. Steel rims are durable and economical but heavier, while alloy rims are lighter and more corrosion-resistant, though typically more expensive. In high-end applications, carbon fiber or forged aluminum rims offer reduced weight and increased stiffness. Rims have a bead seat diameter (BSD) and a width specification, which must match the tire and the hub configuration for proper fit and performance.

Sizes and compatibility are defined by diameter in inches for automotive rims (for example, 15", 16", 17"), and by width, which affects tire mounting and ride characteristics. For bicycles, common diameters include 26", 27.5" (650B), 29", and 700C, with tires chosen to match both rim diameter and width. Tire type (tubed or tubeless) and bead seat requirements influence the selection of jantlar as well.

Maintenance and safety considerations include inspecting rims for cracks, dents, or bending, particularly after impact. Corrosion around spoke holes or valve areas should be checked, and proper mounting with correct torque is essential to avoid bead leaks or rim failure. Regular inspection by qualified technicians helps ensure alignment, balance, and overall wheel integrity.

Etymology-wise, jante is the French word for rim, from which the Turkish term jant is derived; jantlar simply denotes the rims collectively in Turkish usage.
