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
A front-wheel drive Corvette C6 Convertible still wants even corners. 2.2-2.4 vs 2.2-2.4 is an axle split, not a left-right split. TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.
Bar, PSI and kPa
Bar-led conversions around the Corvette C6 Convertible. 2.2-2.4 bar is not “32-35 divided by ten”.

Corvette C6 Convertible placard versus sidewall
If the Corvette sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.
Estimated pressure by tyre size (225/45R17 and others)
If your Corvette C6 Convertible no longer wears the OEM diameter, start at the row nearest 225/45R17 or 225/40R18 and confirm with the tyre maker’s load table.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 225/45R17 | 34 | 35 | 2.34 | 2.41 | 234 | 241 | Front sport size |
| 225/40R18 | 35 | 35 | 2.41 | 2.41 | 241 | 241 | Front 18-inch |
| 235/35R19 | 36 | 36 | 2.48 | 2.48 | 248 | 248 | Front 19-inch |
| 275/30R19 | 36 | 37 | 2.48 | 2.55 | 248 | 255 | Rear 19-inch |
| 255/35R18 | 35 | 36 | 2.41 | 2.48 | 241 | 248 | Rear stagger 18-inch |
| 245/40R18 | 35 | 36 | 2.41 | 2.48 | 241 | 248 | Square-ish sport |
| 275/35R18 | 36 | 37 | 2.48 | 2.55 | 248 | 255 | Wide rear |

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 | 38 psi / 2.62 bar |
How to set the C6 Convertible
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep C6 Convertible 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 C6 Convertible.
| 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 |
Corvette notes
No special Corvette exception: the C6 Convertible 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 Corvette C6 Convertible 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 Corvette sticker and this page disagree, the sticker wins.

Questions about this C6 Convertible
Front versus rear on the Corvette C6 Convertible?
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 C6 Convertible?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
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.
What tyre pressure should a Corvette C6 Convertible 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 Corvette C6 Convertible?
No. Sidewall PSI is a maximum. The C6 Convertible placard is the operating target, near 32-35/32-35 psi.
