A front-wheel drive ARI Bruni still wants even corners. 2.2-2.4 vs 2.2-2.4 is an axle split, not a left-right split. TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.

Bar, PSI and kPa

Bar-led conversions around the ARI Bruni. 2.2-2.4 bar is not “32-35 divided by ten”.

ARI Bruni placard versus sidewall

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

Estimated pressure by tyre size (185/65R15 and others)

185/65R15 is the first planning size here. 215/50R17 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 Bruni

  1. Park the ARI Bruni for at least three hours (cold tyres).
  2. Use a calibrated gauge, not the only meter on a forecourt hose.
  3. Set the placard for that axle — about 32-35 psi / 2.2-2.4 bar front and 32-35 psi / 2.2-2.4 bar rear on this catalogue row.
  4. Recheck all four. A 2 psi miss on a front-wheel drive Bruni is enough to feel a pull.
  5. Refit valve caps and reset TPMS if the handbook asks for a relearn.

Temperature drift

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

ARI notes

No special ARI exception: the Bruni 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 ARI Bruni 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.

Keep the ARI Bruni on the printed band; use 185/65R15 and 215/50R17 only as a map for non-OEM wheels.

Questions about this Bruni

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.

How often should I check a Bruni?

Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.

What PSI if I plus-size toward 215/50R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 185/65R15, 195/65R15 and 215/50R17 as a planning band.

What is that in bar and kPa for the Bruni?

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

What tyre pressure should a ARI Bruni 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.
