On a Karma Pininfarina GT the useful pair is 34 psi (2.31 bar) up front and 34 psi (2.31 bar) at the back, mid-range. TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.

Karma notes

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

Estimated pressure by tyre size (205/55R16 and others)

205/55R16 is the first planning size here. 215/55R16 is usually the plus-size or LT step. Keep load index at or above original equipment.

Karma Pininfarina GT placard versus sidewall

The tyre-information placard on a Karma Pininfarina GT sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.

Pressure against load

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

Driver only34 psi / 2.34 bar34 psi / 2.34 bar
Full occupancy35 psi / 2.41 bar36 psi / 2.48 bar
Motorway + luggage36 psi / 2.48 bar38 psi / 2.62 bar

Spare and inflator kit

A matching full-size spare on the Karma Pininfarina GT 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.

PSI, bar and kPa

1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Mid-points on the Pininfarina GT: 34 psi = 2.31 bar = 231 kPa.

How to set the Pininfarina GT

  1. Park the Karma Pininfarina GT 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 Pininfarina GT is enough to feel a pull.
  5. Refit valve caps and reset TPMS if the handbook asks for a relearn.

Temperature and a cold gauge

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

A cheap gauge and a monthly habit will do more for this Pininfarina GT than nitrogen upsells.

Questions about this Pininfarina GT

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.

When does TPMS warn on a Karma Pininfarina GT?

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

How often should I check a Pininfarina GT?

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

What PSI if I plus-size toward 215/55R16?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 205/55R16, 225/45R17 and 215/55R16 as a planning band.

What tyre pressure should a Karma Pininfarina GT 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.
