A front-wheel drive Tasso TD still wants even corners. 2.2-2.4 vs 2.2-2.4 is an axle split, not a left-right split. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed Tasso tyre.

Tasso TD placard versus sidewall

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

Estimated pressure by tyre size (195/65R15 and others)

Planning cold pressures for sizes often seen on a passenger car. This TD sample opens with 195/65R15, then 245/40R18 and 225/50R17.

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.

How to set the TD

  1. Measure before the school run, not after the M25.
  2. Write LF / RF / RR / RL. Do not keep TD 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.

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this TD.

Tasso notes

No special Tasso exception: the TD 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 Tasso TD 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 Tasso sticker and this page disagree, the sticker wins.

Questions about this TD

What is that in bar and kPa for the TD?

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

What PSI if I plus-size toward 225/50R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 195/65R15, 245/40R18 and 225/50R17 as a planning band.

Is the sidewall number correct on a Tasso TD?

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

How often should I check a TD?

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

What tyre pressure should a Tasso TD 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.
