## Tire Pressure and Temperature
Tire pressure changes by approximately 1 PSI for every 10°F change in temperature. Underinflated tires waste fuel and wear unevenly.
### Rules of Thumb
**Temperature Adjustment: ~1 PSI per 10°F change**
**Fuel Penalty: ~0.2% per 1 PSI below recommended**
For every 1 PSI underinflated across all four tires, fuel economy drops about 0.2%. At 5 PSI under, that is 1% worse mileage and significantly accelerated tire wear.

Ejemplo Resuelto
Tires at 30 PSI (recommended 35) with a 20°F temperature drop.
- Temperature effect = -20 / 10 = -2 PSI
- Adjusted pressure = 30 + (-2) = 28 PSI
- Underinflation = 35 - 30 = 5 PSI
- Fuel penalty = 5 x 0.2% = 1.0%
