Calculation steps

1Convert to bar first: 2.5 bar × 1 = 2.5000 bar
2bar → psi: 2.5000 ÷ 0.0689476 = 36.3 psi
3bar → kPa: 2.5000 ÷ 0.01 = 250.0 kPa
4bar → kgf/cm²: 2.5000 ÷ 0.980665 = 2.549 kgf/cm²

Typical recommended pressures (bar, cold tire)

Vehicle	Front	Rear
sedan	2.2–2.5	2.2–2.5
sedan-full	2.4–2.6	2.6–2.9
suv	2.3–2.5	2.3–2.6
suv-full	2.5–2.8	2.8–3.0
mpv	2.4–2.6	2.6–2.9
ev	2.5–2.9	2.5–3.0

Always follow the sticker on your door frame or fuel cap first.

Measure cold (before driving or 3h after). Tire pressure drops ~0.07–0.1 bar per 10 °C temperature fall — top up in winter. 1 bar ≈ 14.5 psi = 100 kPa; US manuals quote psi, European ones bar.
