Edit any field — the other two recompute live. NIST-exact factor: 1 bar = 14.5037738 psi

What this means for your tires

Typical passenger car

2.5 bar is 36.26 psi (250 kPa) — within the typical passenger car cold-pressure range. Most US sedans and crossovers spec 30–36 psi on the door-jamb sticker.

Quick reference — common cold tire pressures

Compact

2.0–2.2 bar / 29–32 psi

Mid-size

2.2–2.4 bar / 32–35 psi

SUV / crossover

2.4–2.7 bar / 35–39 psi

Light truck

2.5–3.0 bar / 36–44 psi

Conversion uses NIST exact values. Always inflate to your vehicle's door-jamb sticker (or owner's manual) — not a generic 32 psi rule. Pressures rise ~1 psi per 10°F warming; check cold (after the car has sat 3+ hours). Mike Reeves is an ASE Master Technician, not your alignment shop.
