Hyundai i30 (PD): Tyres and wheels / Recommended cold tyre inflation pressures

All tyre pressures (including the spare) should be checked when the tyres are cold. “Cold tyres” means the vehicle has not been driven for at least three hours or has been driven for less than 1 mile (1.6 km).

Warm tyres normally exceed recommended cold tyre pressures by 4 to 6 psi (28 to 41 kPa). Do not release air from warm tyres to adjust the pressure or the tyres will be under-inflated. For recommended inflation pressure, refer to “Tyre and Wheels” in chapter 8.

WARNING

Recommended pressures must be maintained for the best ride, vehicle handling, and minimum tyre wear.

Over-inflation or under-inflation can reduce tyre life, adversely affect vehicle handling, and lead to sudden tyre failure that could result in loss of vehicle control resulting in an accident.

Severe under-inflation can lead to severe heat build-up, causing blowouts, tread separation and other tyre failures that can result in the loss of vehicle control resulting in an accident. This risk is much higher on hot days and when driving for long periods at high speeds.

CAUTION

• Under-inflation results in excessive wear, poor handling and reduced fuel economy. Wheel deformation is also possible. Keep your tyre pressures at the proper levels. If a tyre frequently needs refilling, we recommend it be checked by a HYUNDAI authorised repairer.
• Over-inflation produces a harsh ride, excessive wear at the centre of the tyre tread, and a greater possibility of damage from road hazards.
