32-35 psi F · 32-35 psi R · 2.2-2.4 / 2.2-2.4 bar · 231/231 kPa
Loaded Aston Martin rears often need the sticker’s second column, not a copy of the front 32-35 psi figure. Under-inflation cooks the shoulders of a Aston Martin; over-inflation wears the centre rib and bangs every cat’s eye.
Oldtimer Aston Martin placard versus sidewall
The tyre-information placard on a Oldtimer Aston Martin sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.
Estimated pressure by tyre size (225/40R18 and others)
Planning cold pressures for sizes often seen on a passenger car. This Aston Martin sample opens with 225/40R18, then 205/60R16 and 205/55R16.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 225/40R18 | — | 36 | — | 2.48 | — | 248 | Low-profile 18-inch |
| 205/60R16 | — | 34 | — | 2.34 | — | 234 | Taller 16-inch |
| 205/55R16 | — | 34 | — | 2.34 | — | 234 | Typical mid-compact OEM |
| 225/50R17 | — | 35 | — | 2.41 | — | 241 | Touring 17-inch |
| 215/50R17 | — | 35 | — | 2.41 | — | 241 | Plus-size 17-inch |
| 215/55R16 | — | 35 | — | 2.41 | — | 241 | Slightly wider 16-inch |
| 245/40R18 | — | 36 | — | 2.48 | — | 248 | Wide touring 18-inch |
| 225/45R17 | — | 35 | — | 2.41 | — | 241 | Sport 17-inch |
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 | 35 psi / 2.41 bar | 36 psi / 2.48 bar |
| Motorway + luggage | 36 psi / 2.48 bar | 36 psi / 2.48 bar |
A family passenger car with a boot full of luggage should use the laden rear figure if Ford, VW or Mercedes printed one. Otherwise the modest steps in the load table are only a sketch for this Aston Martin.
How to set the Aston Martin
- Park the Oldtimer Aston Martin 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 Aston Martin is enough to feel a pull.
- 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 Aston Martin.
| 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 Aston Martin 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 Aston Martin 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.
If the Oldtimer sticker and this page disagree, the sticker wins.

Questions about this Aston Martin
Front versus rear on the Oldtimer Aston Martin?
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.
How often should I check a Aston Martin?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
Is the sidewall number correct on a Oldtimer Aston Martin?
No. Sidewall PSI is a maximum. The Aston Martin placard is the operating target, near 32-35/32-35 psi.
What tyre pressure should a Oldtimer Aston Martin 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.
What PSI if I plus-size toward 205/55R16?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 225/40R18, 205/60R16 and 205/55R16 as a planning band.
