Recommended bar for a NSU Prinz 1000 TT

Drivetrain: front-wheel drive
Body: passenger car
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

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

European and UK handbooks usually quote bar. The NSU Prinz 1000 TT catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed NSU tyre.

Estimated pressure by tyre size (215/55R16 and others)

Planning cold pressures for sizes often seen on a passenger car. This Prinz 1000 TT sample opens with 215/55R16, then 185/65R15 and 205/60R16.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-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
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-inch
225/50R17	35	35	2.41	2.41	241	241	Touring 17-inch
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch
195/65R15	34	34	2.34	2.34	234	234	Very common compact
215/50R17	35	35	2.41	2.41	241	241	Plus-size 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	36 psi / 2.48 bar

How to set the Prinz 1000 TT

Park the NSU Prinz 1000 TT 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 Prinz 1000 TT 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 Prinz 1000 TT.

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

NSU notes

No special NSU exception: the Prinz 1000 TT 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 NSU Prinz 1000 TT 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.

Keep the NSU Prinz 1000 TT on the printed band; use 215/55R16 and 205/60R16 only as a map for non-OEM wheels.

Questions about this Prinz 1000 TT

When does TPMS warn on a NSU Prinz 1000 TT?

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

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.

Is the sidewall number correct on a NSU Prinz 1000 TT?

No. Sidewall PSI is a maximum. The Prinz 1000 TT placard is the operating target, near 32-35/32-35 psi.

Front versus rear on the NSU Prinz 1000 TT?

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 Prinz 1000 TT?

Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
