If a Valera owner asks “what PSI?”, start at 34 at the steering axle and 34 at the rear, then confirm the placard. TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.

Daihatsu Valera placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this Valera is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (245/40R18 and others)

Planning cold pressures for sizes often seen on a passenger car. This Valera sample opens with 245/40R18, then 225/45R17 and 195/65R15.

How to set the Valera

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

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.

Daihatsu notes

No special Daihatsu exception: the Valera 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 Daihatsu Valera 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 Daihatsu sticker and this page disagree, the sticker wins.

Questions about this Valera

What is that in bar and kPa for the Valera?

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

What tyre pressure should a Daihatsu Valera 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.

Should I bleed pressure after a motorway run?

No. Heat raises the gauge. Set cold only. Bleeding a hot tyre leaves it low the next morning.

What PSI if I plus-size toward 195/65R15?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/40R18, 225/45R17 and 195/65R15 as a planning band.

Is the sidewall number correct on a Daihatsu Valera?

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