## Description

**Tire Size Fitment** is a tire and wheel fitment calculator for comparing current and prospective setups. Enter tire and rim sizes to view accurate cross-section drawings, scaled up to 6x, with measurements for width, diameter, offset, backspace, poke, inset, clearance, scrub radius, ride height, and arch gap.

Compare up to six setups with front and rear axle support for staggered fitments. Browse factory wheel specifications by vehicle make, year, and model, switch between metric and high-flotation tire notation, use your preferred units and language, and share the complete comparison as an image. The calculator, drawings, measurements, sharing, and core settings are free; a subscription unlocks the vehicle catalog, rear-axle fitments, and multiple setups.

## Review summary

Users praise Tire Size Fitment for its clean, ad-free interface and reliable fitment tools. They value its visual size/offset comparisons and long-term usefulness. Common drawbacks include speedometer inaccuracy when upsizing, no imperial unit support, graphical view limits for large tires, and requests for more clearance measurements. Overall, it’s a popular, free tool with room for improvement in units, speedometer accuracy, and expanded clearance data.

### Pros

- Clean, simple interface with no ads, making it easy to learn and use.
- Very useful for tire/wheel fitment planning, with adjustable offsets and side-by-side tire comparisons.
- Great visual fitment tool that shows how different sizes and wheels look together.
- Longstanding, purpose-built app that is free (donations appreciated) and respects user privacy (no data-mining).

### Cons

- Speedometer accuracy can be incorrect for upsized tires, potentially misleading about actual speeds.
- Lacks imperial/inch units; metric-only or difficult to switch between units.
- Large tires can exceed the display area, making it hard to view or compare multiple options.
- Would benefit from additional clearance inputs (e.g., knuckle/brake caliper clearance) for more complete fits.
