The rear of a passenger car takes passengers, luggage and, on vans, payload. Catalogue rear pressure on the Oldtimer Bizzarrini is 32-35 psi / 2.2-2.4 bar. Size estimates on this page include 185/65R15, 225/40R18 and 195/65R15 — interpolated from the catalogue midpoint, not a second factory sticker.

If the Oldtimer sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.

Estimated pressure by tyre size (185/65R15 and others)

If your Oldtimer Bizzarrini no longer wears the OEM diameter, start at the row nearest 185/65R15 or 225/40R18 and confirm with the tyre maker’s load table.

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.

ConditionFront (est.)Rear (est.)
Driver only34 psi / 2.34 bar34 psi / 2.34 bar
Full occupancy35 psi / 2.41 bar36 psi / 2.48 bar
Motorway + luggage36 psi / 2.48 bar36 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 Bizzarrini.

How to set the Bizzarrini

  1. Measure before the school run, not after the M25.
  2. Write LF / RF / RR / RL. Do not keep Bizzarrini numbers in your head.
  3. Add air in short bursts toward 34 psi (2.31 bar) front and 34 psi rear.
  4. If one corner is 4 psi down, hunt for a nail before you blame the weather.
  5. Log date, ambient temperature and the four readings.

Oldtimer notes

No special Oldtimer exception: the Bizzarrini 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 Bizzarrini 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 Bizzarrini

What is that in bar and kPa for the Bizzarrini?

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

Front versus rear on the Oldtimer Bizzarrini?

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.

Is the sidewall number correct on a Oldtimer Bizzarrini?

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

What tyre pressure should a Oldtimer Bizzarrini 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 195/65R15?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 185/65R15, 225/40R18 and 195/65R15 as a planning band.
