Wheel hub J value refers to the width of the wheel hub. The detailed explanation of J value and the description of wheel hub ET value are as follows: Detailed explanation of wheel hub J value: 7J, 8J in wheel hubs represent the width of the wheel hub, which is the distance between the two flanges of the wheel hub. J represents the shape and height of the wheel hub flange (there are also other heights such as C, JJ, JK, K, etc., with C being the lowest and K being the highest). The width of the wheel hub determines the width of the tire that can be installed. Description of wheel hub ET value: Wheel hub ET value refers to the offset of the wheel hub, which is the distance from the centerline of the wheel hub to the mounting surface, measured in mm, and determines whether it will rub against the vehicle body. The smaller the offset, the more the wheel hub will protrude outside the vehicle after installation. The offset determines whether the wheel hub will rub against vehicle components. If the new wheel hub has a larger offset than the original wheel hub, or if the width is too large, it may cause friction with the vehicle's suspension system.
