This front-wheel drive passenger car is filed here with a working range of 32-35/32-35 psi. The pillar sticker on your VIN still overrides the website. Size estimates on this page include 215/50R17, 215/55R16 and 185/65R15 — interpolated from the catalogue midpoint, not a second factory sticker.

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.

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

How to set the 100-Years-Special

Park the Morgan 100-Years-Special for at least three hours (cold tyres).
Use a calibrated gauge, not the only meter on a forecourt hose.
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.
Recheck all four. A 2 psi miss on a front-wheel drive 100-Years-Special is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

Estimated pressure by tyre size (215/50R17 and others)

If your Morgan 100-Years-Special no longer wears the OEM diameter, start at the row nearest 215/50R17 or 215/55R16 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-inch
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch
185/65R15	33	33	2.28	2.28	228	228	Small / older car
205/60R16	34	34	2.34	2.34	234	234	Taller 16-inch
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch

Spare and inflator kit

A matching full-size spare on the Morgan 100-Years-Special 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.

Temperature and a cold gauge

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this 100-Years-Special.

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

Morgan 100-Years-Special placard versus sidewall

The tyre-information placard on a Morgan 100-Years-Special sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.

PSI, bar and kPa

1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Mid-points on the 100-Years-Special: 34 psi = 2.31 bar = 231 kPa.

PSI	Bar	kPa
30	2.07	207
32	2.21	221
33	2.28	228
33.5	2.31	231
35	2.41	241
36	2.48	248
38	2.62	262
40	2.76	276

Morgan notes

No special Morgan exception: the 100-Years-Special uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.

If the Morgan sticker and this page disagree, the sticker wins.

Questions about this 100-Years-Special

What tyre pressure should a Morgan 100-Years-Special 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 Morgan 100-Years-Special?

No. Sidewall PSI is a maximum. The 100-Years-Special placard is the operating target, near 32-35/32-35 psi.

When does TPMS warn on a Morgan 100-Years-Special?

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

What PSI if I plus-size toward 185/65R15?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 215/50R17, 215/55R16 and 185/65R15 as a planning band.

Front versus rear on the Morgan 100-Years-Special?

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.
