Lexus tyre pressure and size guide

This Lexus tyre pressure and size guide answers an important factor that has a direct bearing on everything from safety and ride comfort to fuel economy and responsiveness. Different wheel and tyre combinations require different tyre pressures, and these can sometimes alter between the front and rear of the vehicle.

As the only direct connection to the road surface, the tyres of our cars deserve special attention. They should be in damage-free condition and wearing evenly across the breadth of the tyre and around the entire circumference, to a minimum legal tread depth of 1.6 millimetres.

Lexus tyre pressure

Specific tyre sizes and inflation values are not mandated by law but set by each vehicle manufacturer. The tyre sizes specified from the factory and the pressures that Lexus recommends to inflate them will offer the best possible balance in overall performance in normal road conditions with a modest load on board. You will find this information for all current generation models in the table below.

What if my Lexus is not listed here?

If you have a previous generation model, the recommended size and Lexus tyre pressure values for your vehicle will either be listed on the door jamb around the B-pillar (see example below), on the inside of the glove box, or in the owner’s manual.

Lexus tyre pressure

Please note that if your vehicle is fully laden or will be used for sustained high-speed driving, the Lexus tyre pressure values will need to be increased.
Specific information on this is also shown in the same locations listed above.

    1. Hi there, thanks for your comment.

      Please provide your registration number so we can check on this for you.

      Thanks,

    1. Hi Shirley,
      May we have your vehicles registration so that we may confirm this for you please?
      Kind regards

  2. Hello , i recently had a NX 300h fsport, the tyres are 225-60-R18 , Reg 2016. I checked the tyre pressure at the petrol because the tyre pressure sign was showing at the dashboard, it is actually 48psi, is that ok or need to be reduced for that sign to go off the dashboard?

    1. Hello Malick,thank you for getting in touch.

      Having referred to the owner manual for your year of NX, based on the wheel size provided, your cold tyre pressures should be 2.2bar (32psi) for both front and rear if driving below 100mph. Please adjust the pressures as soon as is possible.

      Thanks,

      Lexus UK

      1. Thank you for your answer, I will do.
        And if I am driving more than 100mph for example travelling abroad or another city, what will you recommend in terms of tyre pressure?

        1. Hello Malick,thank you for the reply.

          The tyre pressure, according to the handbook for the 2016 year of NX, with 235/55 R18 tyres fitted is 2.7 bar (39psi) both front and rear if travelling over 100mph (160kph).

          Thanks,

          Lexus UK
