Wheel modification is a significant part of car culture, but compliance and safety must be prioritized. Non-compliant modifications can lead to inaccurate speedometer readings, interference with vehicle electronic systems, accelerated suspension wear, and even catastrophic failure. Key parameters include PCD (Pitch Circle Diameter), offset (ET value), center bore size, and load rating. When selecting aftermarket wheels, it is crucial to ensure they match the original vehicle specifications or are professionally certified, and they must be paired with correct tires. Safety should always take precedence over personalization.
