Lexus tire pressures
Lexus RX tire pressure
The cold tire pressures Lexus prints in its owner's manuals for each RX tire size, by generation — RX (5th gen, ALA10) (2023 on), RX (4th gen, AL20) (2016–2022) and RX (3rd gen, AL10) (2010–2015). Find your tire size on the sidewall, then read across.

The owner's manual lists these sizes but prints no pressures for them — use the placard on the door jamb.
What the owner's manuals don't say
- Lexus owner's manuals are served only from assets.sia.toyota.com, which refuses requests from outside North America (403 direct, AccessDenied through the r.jina.ai proxy) and no existing archived copy was found; no Lexus document for this generation could be read

Notes from the owner's manuals
- P235/60R18 102V: Read from an existing archived copy of the maker's manual, so marked reported. Type B has a full-size spare at 32 psi (220 kPa, 2.2 bar). Same table in the 2014 RX 350 manual (OM48D08U).
What the owner's manuals don't say
- Only the 2014 and 2015 RX350 manuals were read (archived copies); RX450h and 2010–2013 not read
Figures marked "Owner's manual" link to the maker's own document. "Reported" figures are the maker's, read from a copy we could not get from the maker directly. A figure marked ≈ has been converted from the unit the manual prints. Nothing here has been checked against your vehicle: if it disagrees with the placard on the door jamb, the placard wins.

Tire pressure questions
What should the tire pressure be on a Lexus RX?
It depends on the tire size. For the sizes Lexus lists, the cold pressure is 32–33 psi at the front and 32–33 psi at the rear. Find your size in the tables above, and check the tires cold.
What size tires does a Lexus RX take?
Lexus fitted the RX with 235/60 R18, 235/65 R18, 235/55 R19 and 235/55 R20, depending on the model year and trim. The size is printed on the side of your tire; the pressures above are listed by size.
Where is the tire pressure placard on a Lexus RX?
On the driver's door jamb — the Tire and Loading Information placard. It gives the same cold pressures as the owner's manual, which is where the figures on this page come from; if the two ever disagree, go by the placard on your vehicle.
