A front-wheel drive Opel Sintra still wants even corners. 2.2-2.4 vs 2.2-2.4 is an axle split, not a left-right split. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed Opel tyre.

Opel Sintra placard versus sidewall

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

Estimated pressure by tyre size (215/55R16 and others)

If your Opel Sintra no longer wears the OEM diameter, start at the row nearest 215/55R16 or 225/40R18 and confirm with the tyre maker’s load table.

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 Sintra

  1. Measure before the school run, not after the M25.
  2. Write LF / RF / RR / RL. Do not keep Sintra 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 Sintra.

Opel notes

No special Opel exception: the Sintra 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 Opel Sintra 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 Opel sticker and this page disagree, the sticker wins.

Questions about this Sintra

Front versus rear on the Opel Sintra?

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.

What tyre pressure should a Opel Sintra 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.

When does TPMS warn on a Opel Sintra?

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 Opel Sintra?

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

What PSI if I plus-size toward 245/40R18?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 215/55R16, 225/40R18 and 245/40R18 as a planning band.
