Toyota IQ Wheel Lug Pattern, Offset ET, and Center Bore Reference
The Toyota IQ features specific wheel lug patterns designed to ensure proper fitment and safety. Its lug pattern specifies the number of lug nuts and the pitch circle diameter (PCD in mm), critical for matching wheels to the vehicle. Offset ET and center bore are also essential measurements that affect wheel alignment and mounting.\n\nToyota IQ wheel lug patterns vary slightly depending on the model year, with lug counts typically at 4 or 5 lugs and PCD measurements consistent to maintain compatibility. Offset ET values balance wheel positioning relative to the suspension and fenders.\n\nCenter bore diameter is crucial for centering the wheel on the hub, preventing vibrations, and ensuring stability. Rim sizes suitable for the Toyota IQ range to accommodate original equipment and aftermarket options, matching performance and aesthetics.\n\nFor precise wheel fitment, reference the year-sorted Toyota IQ lug pattern, offset ET, and center bore catalog to select compatible wheels that maintain safety and driving dynamics.
