Wheel Fitment Calculator
Compare your current wheel and tire setup against a new setup to estimate poke, inner clearance, tire diameter, and speedometer change.
Fitment Results
Positive means the new wheel sits farther toward the fender.
Positive means the new wheel sits closer to suspension components.
Keep total tire diameter close to stock for speedometer accuracy.
Estimated actual speed when the speedometer reads 60 mph.
Fitment Visualizer
Front view — current setup vs new setup. The dashed inner box is the wheel; the outer box is the tire. Watch how far the new wheel pokes toward the fender.
How to use this wheel fitment calculator
Enter your current wheel width, offset, and tire size, then compare it with the new setup you are considering. The calculator estimates how much farther the new wheel will sit outward, how much inner clearance changes, and whether tire diameter will affect ride height or speedometer readings.
Fitment depends on more than math. Brake clearance, fender shape, suspension type, alignment, ride height, tire model, and camber all matter. Use this calculator as a planning tool, then contact our fitment team before ordering aggressive setups.
This free wheel fitment calculator — a “will they fit” calculator — lets you compare wheel offset, width, and tire size so you can check poke, clearance, and tire diameter before you buy. Use it as a wheel offset calculator and tire size comparison, then shop wheels that fit your setup.
