Wheel Offset & Backspacing Visualizer

Enter your wheel specs to see how the wheel sits relative to the hub, how much it pokes out or tucks in, and where the rub risk is. Works for any rig — enter your numbers, read the cross-section.

What this tells you — and what it doesn't

Offset and backspacing describe where the wheel sits relative to the mounting face. But whether it actually rubs depends on your specific rig: hub-face-to-fender distance, suspension geometry at full droop and full stuff, UCA/LCA clearance, and brake caliper position. This tool shows you the geometry; it can't substitute for a physical check with the tire on.

General rub-risk thresholds used here: inboard clearance under 2.5" often conflicts with brake calipers and UCA on common solid-axle setups; outboard section over 5.5" is where most fender contact happens on lifted XJ/JK/TJ without flares. IFS trucks (Tacoma, 4Runner, Raptor) are more sensitive to inboard clearance at full compression.

Round-trip check: offset ↔ backspacing math should always round-trip. If you enter an offset, calculate backspacing, then enter that backspacing — you should get the same offset back within rounding.
