Wheel Geometry Studio
Compare two wheel and metric radial tire specifications with shared-scale cross-section and diameter views. Keep wheel bead-seat geometry separate from nominal tire width, record optional static gaps and save the assumptions with a real PDF, SVG, CSV or JSON report.
How we build a check
This workbench processes supported inputs locally. We test calculations, file structure and generated artifacts using independent readers or known fixtures where available. The example runs the same processing path as a supplied input; it does not stand in for checking your own result.
Editorial responsibility
KitForma maintains this tool and its guides. The source notes on the tool page link to the supporting documentation. We do not claim affiliation with the referenced hardware manufacturers or platforms. Review date: 2026-10-19.
Limits and updates
Metric radial notation only, such as 225/45R17: width 125–445 mm, aspect 20–100%, rim diameter 10–30 in. Wheel bead-seat width 3–16 in; offset -100 to +150 mm; spacer 0–100 mm. Numeric bounds are parser limits, not approved equipment ranges.,No vehicle database or mounting approval. Actual tire profile, loaded radius, approved rim widths, load/speed ratings, bolt pattern, center bore, spoke/caliper shape, steering and suspension travel are not evaluated. Spacer input is dimensional arithmetic, not a recommendation.,Measured baseline gaps are optional static tire-envelope measurements in mm. Calculated candidate gaps use nominal dimensions and are not guarantees. No automatic storage; import/export this tool’s JSON up to 20 KB. If a specification changes or a result appears incorrect, send the relevant source URL and a non-sensitive reproduction to kitforma@outlook.com.
