European and UK handbooks usually quote bar. The GEMBALLA Tornado catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed GEMBALLA tyre.

GEMBALLA Tornado placard versus sidewall

If the GEMBALLA sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.

Estimated pressure by tyre size (225/45R17 and others)

225/45R17 is the first planning size here. 205/60R16 is usually the plus-size or LT step. Keep load index at or above original equipment.

Load notes

Load moves the rear of a passenger car first. If the factory placard already has a “laden” column, use that instead of these sketches.

How to set the Tornado

  1. Measure before the school run, not after the M25.
  2. Write LF / RF / RR / RL. Do not keep Tornado numbers in your head.
  3. Add air in short bursts toward 34 psi (2.31 bar) front and 34 psi rear.
  4. If one corner is 4 psi down, hunt for a nail before you blame the weather.
  5. Log date, ambient temperature and the four readings.

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Tornado.

GEMBALLA notes

No special GEMBALLA exception: the Tornado uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.

Spare and inflator kit

A matching full-size spare on the GEMBALLA Tornado usually follows the higher axle (often the rear, near 32-35 psi). A space-saver is commonly 60 psi / 4.1 bar — read that tyre’s own sidewall. An inflator kit is not a spare; check the sealant date.

If the GEMBALLA sticker and this page disagree, the sticker wins.

Questions about this Tornado

What tyre pressure should a GEMBALLA Tornado use?

Catalogue reference is 32-35 psi front and 32-35 psi rear (2.2-2.4 / 2.2-2.4 bar), cold. Confirm on the door-pillar placard.

What is that in bar and kPa for the Tornado?

Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.

When does TPMS warn on a GEMBALLA Tornado?

Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.

Is the sidewall number correct on a GEMBALLA Tornado?

No. Sidewall PSI is a maximum. The Tornado placard is the operating target, near 32-35/32-35 psi.

Front versus rear on the GEMBALLA Tornado?

This row is 32-35 F / 32-35 R. Even when they match, a laden rear can justify a higher number if the sticker prints one.
