## What It Does
- Temperature correction: Corrects cold pressure for a temperature swing, roughly 1 psi per 10 degrees Fahrenheit.
- Load-range context: How SL, C, D, and E tires differ in pressure and why LT tires need more pressure for the same load.
- Tacoma pressures: Placard pressure near 35 psi, typical daily pressures, and why 80 psi is a maximum, not a daily setting.

## Summary
- Adjusts cold tire pressure for a change in ambient temperature, about 2 percent per 10 degrees Fahrenheit.
- Explains load-range pressures and that an LT tire needs more pressure than a P-metric tire for the same load.
- Tacoma placard pressure is around 35 psi; never daily-drive an E tire at its 80 psi maximum.

## FAQ
### How much does tire pressure change with temperature?
About 2 percent per 10 degrees Fahrenheit, which is roughly 1 psi per 10 degrees on a passenger tire near 35 psi. Pressure rises as it warms and falls as it cools.

### What tire pressure should I run on my Tacoma?
Start from the door placard, usually around 35 psi for factory SL tires. Owners running load-range E tires often use about 36 to 40 psi daily and air down off-road.

### Should I run E tires at 80 psi?
No. 80 psi is the maximum inflation for a load-range E tire, not a daily setting. Running it that high on an empty mid-size truck rides harshly and wears the center.
