# Wheel Spacer Calculator

See how a wheel spacer changes Tacoma offset, poke, and track width. A spacer works exactly like reducing offset by its thickness.

## What It Does
- Effective offset: A spacer reduces offset by its thickness; see the resulting effective offset instantly.
- Poke and track width: Each corner moves out by the spacer thickness, adding twice that to axle track width.
- Tacoma spacer notes: Hub-centric bores, the 1.25 inch daily max, and why 3rd and 4th gen spacers do not swap.

## Summary
- Calculates effective offset, outward poke, and track-width change from a wheel spacer.
- A spacer is identical to reducing wheel offset by its thickness; each inch is about 25.4 mm.
- 1.25 inch is the common daily-driver maximum, and 3rd and 4th gen spacers are not interchangeable.

## FAQ
### How much offset is a 1 inch wheel spacer?
A 1 inch spacer is about 25.4 mm, so it reduces effective offset by roughly 25 mm and pushes each wheel out about 1 inch.

### Are wheel spacers safe on a Tacoma?
Hub-centric spacers up to about 1.25 inch are widely considered safe for daily use and stress the wheel bearing no more than an equally aggressive low-offset wheel. Larger sizes are better handled with correct-offset wheels.

### Do 3rd gen spacers fit a 4th gen Tacoma?
No. 3rd gen and earlier use a 106.1 mm hub with M12x1.5 studs, while the 4th gen uses a 95.1 mm hub with M14x1.5 studs, so the spacers are not interchangeable.
