LT215/85R16

50 psi / 3.45 bar

345 kPa · estimates for this size class

LT215/85R16 · 50 psi · 3.45 bar · 345 kPa — estimates. Placard wins.

Searches for “LT215/85R16 pressure” usually want a number. Use 50 psi (3.45 bar) only as a sketch; the door-pillar placard on the car that wears this size still wins. Under-inflation cooks the shoulders of a LT215/85R16; over-inflation wears the centre rib and bangs every cat’s eye. LT-metric sizes print a load range. The vehicle door sticker, not the LT sidewall maximum, is still the operating pressure.

What LT215/85R16 means

Read LT215/85R16 as width / aspect R rim. Nothing in the size string is a pressure. Pressure lives on the car, not moulded as 205 or 55.

LT commercial 16-inch. Rim diameter 16 in; section 215 mm. Estimates on this page assume a typical load index for the LT-metric truck class.

Estimated LT215/85R16 pressure by load

These LT215/85R16 load steps are ± a few PSI from 50. They are not a licence to ignore a printed second column on a van or estate.

Placard versus sidewall

This website maps size searches such as “LT215/85R16 psi”. It does not replace the VIN label. If the two disagree, the label wins.

How to set LT215/85R16

  1. Measure before the school run, not after the motorway.
  2. Write LF / RF / RR / RL. Do not keep LT215/85R16 numbers in your head.
  3. Add air in short bursts toward the placard, using 50 psi only as a map.
  4. If one LT215/85R16 is 4 psi down, hunt for a nail before you blame the weather.
  5. Log date, ambient temperature and the four readings.

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 50 psi as a 20 °C baseline for LT215/85R16.

Questions about LT215/85R16

When does TPMS warn on LT215/85R16?

Direct TPMS typically flags about 25% below target — near 38 psi if you were aiming at 50. Fill to the sticker, not to the lamp.

Is LT215/85R16 the same as a plus-size swap?

Only if that is the size you fitted. Overall diameter should stay close to OEM. Pressure still follows the car, with load index at or above original.

Can I run LT215/85R16 at a lower pressure for comfort?

Not as a habit. A soft LT215/85R16 cooks the shoulders and dulls steering. Keep load index and stay on the placard.

What PSI should LT215/85R16 tyres be?

A LT-metric truck planning figure is about 50 psi cold (3.45 bar / 345 kPa). Confirm on the vehicle placard — two cars can share LT215/85R16 and not share a sticker.

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.
