Oldtimer Panther bar chart (2.2-2.4 / 2.2-2.4)

Drivetrain: front-wheel drive
Body: passenger car
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

2.31 / 2.31

32-35 / 32-35 psi · 231 / 231 kPa

32-35 psi F · 32-35 psi R · 2.2-2.4 / 2.2-2.4 bar · 231/231 kPa

European and UK handbooks usually quote bar. The Oldtimer Panther catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). Under-inflation cooks the shoulders of a Panther; over-inflation wears the centre rib and bangs every cat’s eye.

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

Oldtimer Panther placard versus sidewall

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

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

205/55R16 is the first planning size here. 195/65R15 is usually the plus-size or LT step. Keep load index at or above original equipment.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
185/65R15	33	33	2.28	2.28	228	228	Small / older car
195/65R15	34	34	2.34	2.34	234	234	Very common compact
225/50R17	35	35	2.41	2.41	241	241	Touring 17-inch
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-inch
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-inch
225/45R17	35	35	2.41	2.41	241	241	Sport 17-inch
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch

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.

Condition	Front (est.)	Rear (est.)
Driver only	34 psi / 2.34 bar	34 psi / 2.34 bar
Full occupancy	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 bar	37 psi / 2.55 bar

How to set the Panther

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep Panther numbers in your head.
Add air in short bursts toward 34 psi (2.31 bar) front and 34 psi rear.
If one corner is 4 psi down, hunt for a nail before you blame the weather.
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 Panther.

Ambient	Gauge (front mid)	Bar	kPa	Note
−5 °C (hard frost)	31 psi	2.14 bar	214 kPa	Gauge reads low; do not overfill once warm
0 °C	32 psi	2.21 bar	221 kPa	Gauge reads low; do not overfill once warm
8 °C (UK winter morning)	33 psi	2.28 bar	228 kPa	Gauge reads low; do not overfill once warm
20 °C (set cold here)	34 psi	2.34 bar	234 kPa	Baseline
30 °C	36 psi	2.48 bar	248 kPa	Do not bleed a hot tyre
38 °C (heatwave tarmac)	37 psi	2.55 bar	255 kPa	Do not bleed a hot tyre

Oldtimer notes

No special Oldtimer exception: the Panther 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 Oldtimer Panther 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 Panther than nitrogen upsells.

Questions about this Panther

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 205/55R16, 185/65R15 and 195/65R15 as a planning band.

How often should I check a Panther?

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

Front versus rear on the Oldtimer Panther?

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.

Is the sidewall number correct on a Oldtimer Panther?

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

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.
