Cold means the Oldtimer RenT Bonnet 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 205/55R16, 215/50R17 and 185/65R15 — 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 RenT Bonnet.

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 RenT Bonnet

Park the Oldtimer RenT Bonnet 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 RenT Bonnet is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

Oldtimer RenT Bonnet placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this RenT Bonnet is the pillar sticker, near 34/34 psi.

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

If your Oldtimer RenT Bonnet no longer wears the OEM diameter, start at the row nearest 205/55R16 or 215/50R17 and confirm with the tyre maker’s load table.

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
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-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
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-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 RenT Bonnet 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 RenT Bonnet 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 RenT Bonnet

Front versus rear on the Oldtimer RenT Bonnet?

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 RenT Bonnet?

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 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 205/55R16, 215/50R17 and 185/65R15 as a planning band.

What is that in bar and kPa for the RenT Bonnet?

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