20×9

20x9 is a common wheel size for many vehicles, particularly trucks and SUVs. The "20" refers to the diameter of the wheel in inches, meaning it measures 20 inches across. The "9" refers to the width of the wheel in inches, indicating it is 9 inches wide from bead seat to bead seat.

This wheel size is often chosen for aesthetic reasons, as larger diameter wheels can give a vehicle a more aggressive or sporty look. However, larger wheels can also impact ride comfort and tire performance. Tires designed for 20x9 wheels will have a corresponding aspect ratio and load rating suitable for the vehicle's intended use.

The offset of a 20x9 wheel is also a critical measurement, determining how far the wheel sits inward or outward from the hub. Proper offset is crucial for ensuring the wheels clear suspension components and fenders, and it also affects the vehicle's handling characteristics.

When considering 20x9 wheels, it's important to ensure compatibility with the vehicle's bolt pattern and center bore. The bolt pattern is the number and spacing of the lug holes, while the center bore is the diameter of the hub opening. Using incorrect specifications can lead to improper fitment and potential safety hazards.
