Cold means the Oldtimer Corvette has stood at least three hours, or covered less than about a mile. Heat from a dual carriageway run is not the number you set. Size estimates on this page include 225/45R17, 245/40R18 and 235/35R19 — interpolated from the catalogue midpoint, not a second factory sticker.

Temperature and a cold gauge

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

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

How to set the Corvette

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

Oldtimer Corvette placard versus sidewall

The tyre-information placard on a Oldtimer Corvette 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 (225/45R17 and others)

225/45R17 is the first planning size here. 235/35R19 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
225/45R17	34	35	2.34	2.41	234	241	Front sport size
245/40R18	35	36	2.41	2.48	241	248	Square-ish sport
235/35R19	36	36	2.48	2.48	248	248	Front 19-inch
275/35R18	36	37	2.48	2.55	248	255	Wide rear
225/40R18	35	35	2.41	2.41	241	241	Front 18-inch
255/35R18	35	36	2.41	2.48	241	248	Rear stagger 18-inch
275/30R19	36	37	2.48	2.55	248	255	Rear 19-inch
255/40R17	35	36	2.41	2.48	241	248	Rear stagger 17-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	34 psi / 2.34 bar	35 psi / 2.41 bar
Motorway + luggage	35 psi / 2.41 bar	37 psi / 2.55 bar

Oldtimer notes

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

Questions about this Corvette

Front versus rear on the Oldtimer Corvette?

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.

What is that in bar and kPa for the Corvette?

Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.

When does TPMS warn on a Oldtimer Corvette?

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

What tyre pressure should a Oldtimer Corvette 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 235/35R19?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 225/45R17, 245/40R18 and 235/35R19 as a planning band.
