A 3 psi miss on one front corner of this LJ 80 shows up as a wander before the TPMS lamp bothers you. Target 34 psi (2.31 bar) cold. Under-inflation cooks the shoulders of a LJ 80; over-inflation wears the centre rib and bangs every cat’s eye.
Suzuki LJ 80 placard versus sidewall
Sidewall PSI is a carcass maximum. Recommended operating pressure for this LJ 80 is the pillar sticker, near 34/34 psi.
Estimated pressure by tyre size (225/40R18 and others)
Planning cold pressures for sizes often seen on a passenger car. This LJ 80 sample opens with 225/40R18, then 195/65R15 and 215/55R16.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 225/40R18 | 36 | — | 2.48 | — | 248 | — | Low-profile 18-inch |
| 195/65R15 | 34 | — | 2.34 | — | 234 | — | Very common compact |
| 215/55R16 | 34 | — | 2.34 | — | 234 | — | Slightly wider 16-inch |
| 215/50R17 | 35 | — | 2.41 | — | 241 | — | Plus-size 17-inch |
| 205/60R16 | 34 | — | 2.34 | — | 234 | — | Taller 16-inch |
| 245/40R18 | 36 | — | 2.48 | — | 248 | — | Wide touring 18-inch |
| 225/50R17 | 35 | — | 2.41 | — | 241 | — | Touring 17-inch |
| 225/45R17 | 35 | — | 2.41 | — | 241 | — | Sport 17-inch |
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.
| 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 |
Steering feel on the LJ 80 lives on this axle. Do not drop front pressure to “soften” a plus-size 215/55R16; you will roll the sidewall in a roundabout.
How to set the LJ 80
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep LJ 80 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 LJ 80.
| 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 |
Suzuki notes
No special Suzuki exception: the LJ 80 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 Suzuki LJ 80 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 Suzuki sticker and this page disagree, the sticker wins.

Questions about this LJ 80
What is that in bar and kPa for the LJ 80?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
How often should I check a LJ 80?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
When does TPMS warn on a Suzuki LJ 80?
Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.
Is the sidewall number correct on a Suzuki LJ 80?
No. Sidewall PSI is a maximum. The LJ 80 placard is the operating target, near 32-35/32-35 psi.
What tyre pressure should a Suzuki LJ 80 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.
