Recommended pressure means the vehicle placard, not the tyre sidewall. For a Plymouth Prowler the catalogue proxy is 32-35/32-35 psi (2.2-2.4/2.2-2.4 bar). Size estimates on this page include 245/40R18, 215/55R16 and 225/50R17 — interpolated from the catalogue midpoint, not a second factory sticker.

How to set the Prowler

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

Plymouth Prowler placard versus sidewall

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

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

245/40R18 is the first planning size here. 225/50R17 is usually the plus-size or LT step. Keep load index at or above original equipment.

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.

Temperature drift

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

Plymouth notes

No special Plymouth exception: the Prowler 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 Plymouth Prowler 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.

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

Questions about this Prowler

What tyre pressure should a Plymouth Prowler 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.

Is the sidewall number correct on a Plymouth Prowler?

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

When does TPMS warn on a Plymouth Prowler?

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 Prowler?

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

What PSI if I plus-size toward 225/50R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/40R18, 215/55R16 and 225/50R17 as a planning band.
