Optimize your vehicle's stance and ensure perfect fitment for aftermarket wheels and tires with our Custom Wheel Offset & Tire Clearance Calculator. Easily determine the ideal wheel offset, backspacing, and crucial tire clearance changes to avoid rubbing and achieve your desired look. Input your current and new wheel specs to get instant, accurate results.
Formula:
This calculator helps determine the impact of new wheels on your vehicle's fitment. It computes backspacing, change in inner clearance (towards suspension/inner fender), and change in outer clearance (towards fender lip) based on your current and proposed wheel dimensions.
Old Wheel Width: Your current wheel width (e.g., 8.0 inches)Old Offset: Your current wheel offset (e.g., +35 mm)New Wheel Width: Your desired new wheel width (e.g., 9.5 inches)New Offset: Your desired new wheel offset (e.g., +20 mm)
Change in Inner Clearance and Change in Outer Clearance, indicating how much your wheel moves inward or outward.
