Tire Inflation Calculator
Calculate the correct tire pressure for your vehicle with our comprehensive calculator. Determine optimal PSI based on vehicle weight, tire size, load, and driving conditions.
Step 1: Vehicle & Tire Specifications
Understanding Tire Pressure
Proper tire pressure is essential for safety, fuel efficiency, and tire longevity. Underinflated tires increase rolling resistance and wear, while overinflation reduces traction.
Step 2: Driving Conditions & Load
About Pressure Adjustments
Increase pressure by 2-4 PSI for highway driving, decrease slightly for winter conditions, and adjust for heavy loads. Always check manufacturer recommendations in your vehicle’s door jamb.

Tire Pressure Guidelines
Optimal Pressure = Base Pressure × Load Factor × Condition Factor
Base pressure varies by vehicle and tire size. Load factor adjusts for passengers/cargo (1.0 for normal, 1.1 for heavy). Condition factor adjusts for driving type (1.05 for highway, 0.98 for winter).
