I have a TPMS display without readings, I wondered since the tires are low aspect performance tires whether Lexus did not use a TPMS.

Definitely comes with TPMS. Sometimes on cold start they will not show readings until you drive a little. Could also be that you have something interfering with the radio waves (e.g., metallic tints).

Yes, your car is supposed to have TPMS. Maybe the TPMS just needs to be reset. Or maybe you are missing the sensors for some reason.

I'm guessing you just recently purchased your 2015 GS 350. Did you purchase it from a Lexus dealership? Is it CPO? Does the car have factory wheels, or aftermarket wheels? Do you know anything about the car's history?

For reference, US law mandates that all new vehicles are required to have TPMS. This has been in place since 2011 or so I believe.

The GS uses a system that indicates pressure readings at each wheel whereas lower end TPMS systems will only alert you that a tire is low, but won't give individual readings or let you know which tire it is.

Were the sensors replaced at some point? I've read instances here where some have gone with aftermarket sensors and they will just show dashes instead of the actual pressures. I went with the OEM Toyota/Lexus ones for the wheels and tires I'll be getting put on soon.

Yes, it is possible maybe they aren't being read. But it should show up if it has them. It is possible that the last time the tires were replaced, either they left them off by accident or they were taken. When I got my car they did not have them, and I suspect someone had taken them prior, so I had to buy new ones, I think it was about $200 for them.
