        "content": "<p>JAKARTA, KOMPAS.com \u2013 Rims are one of the most frequently modified\ncomponents on a car, used to enhance its appearance and character.\nHowever, many car owners replace their rims without paying attention to\nthe appropriate technical specifications.<\/p>\n<p>Kumar from Kickoff Ciputat, a car rim and tyre shop in the Cipayung,\nCiputat area, says that rim replacement should not be done haphazardly\nas it can lead to various risks.<\/p>\n<p>\u201cRims are not just for aesthetics; they also affect comfort and\nsafety while driving. If the size does not match the car\u2019s\nspecifications, the impact can be felt on the handling, suspension, and\nthe durability of components,\u201d Kumar told Kompas.com on Monday\n(23\/2\/2026).<\/p>\n<p>Each rim has an identification code printed on the inside, known as\nthe rim marking. This code contains important information about the\nrim\u2019s specifications, from size to bolt configuration.<\/p>\n<p>The Marketing Division Head of Auto2000, Nur Imansyah Tara, explains\nthat rim markings are actually quite easy to understand. For example, on\na rim, you will usually find codes such as 9x20, 5x112, and ET +20.<\/p>\n<p>The code 9x20 indicates the basic size of the rim. The number 9\nindicates the width of the rim in inches, while the number 20 is the\ndiameter of the rim in inches. This means that the rim has a width of 9\ninches and a diameter of 20 inches.<\/p>\n<p>The code 5x112, on the other hand, relates to the wheel bolt pattern\nor Pitch Center Diameter (PCD). The number 5 indicates the number of\nbolts used, while the number 112 indicates the distance between the bolt\nholes in millimeters.<\/p>\n<p>Thus, the rim is designed for a five-bolt mounting system with a bolt\nhole spacing of 112 mm.<\/p>\n<p>In addition to size and bolt pattern, there is also the ET code,\nwhich indicates the rim offset value. The offset is the distance between\nthe centre point of the rim and the bolt mounting surface.<\/p>\n<p>\u201cUsually, the offset is marked with a zero, negative, or positive\nnumber. If the bolt mounting is exactly in the centre, then the offset\nis zero,\u201d said Imansyah.<\/p>\n<p>Conversely, a positive offset indicates that the bolt mounting is\nfurther inwards, making the wheel position closer to the inside of the\nfender.<\/p>\n<p>Understanding these codes is an important step before deciding to\nreplace the rims. With the right specifications, the modification will\nnot only enhance the appearance but also maintain comfort, stability,\nand safety during daily use.<\/p>\n<p>KOMPAS.com is committed to providing clear, trustworthy, and balanced\nfacts.
