I have a 2019 250h F-Sport and I'm losing 0.2bar tyre pressure per month on 1 tyre. Is it worth taking it into a garage to be checked?

Thoughts?

It doesn't hurt.

Off topic but, the lady's IS loses about ~10PSI of air overnight when it goes from warm to cold. Only happens during colder months in Chicago too, nothing in the spring/summer. Strange if you ask me.

No cracks in the rim, no punctures in the tire. Took the car to lexus 3x and they cannot find any issues with the bead seal, etc. either.

Strange. Oh well, when they get powdercoated the coming year, hopefully whatever they discover there or fix in the process will eliminate that hassle.

Good luck, OP.

sounds like a loose valve stem with a tight stem cap.

BAck from Kwik Fit, it's a nail in the tyre, runflat so can't be repaired, new tyre being fitted tomorrow

I was going to suggest a nail or puncture in your tire.

This is my car with run flats, it makes it really difficult to knownif you have a flat since the tire deflates at a slower pace. As oppose to a standard tire which goes flat entirely.
