Frequently asked

What tyre pressure does the Lexus RX (AL10) (2009 – 2015) take?
The recommended cold front tyre pressure is 2.3 bar · 33 psi on 235/60R18 (see the per-fitment table for other sizes and the rear axle) — read from the vehicle's door-pillar placard.
Should I check pressures hot or cold?
Always set tyre pressures cold (before driving, or at least 3 hours after). Pressure rises as tyres warm up, so a “cold” placard value checked hot will read high. Increase the placard pressure for sustained high-speed or fully-laden driving where a separate figure is given.
