TPMS calibration

TPMS is warning (low temperature so not exactly surprising) but I set to wondering if there is a re-calibration? Can't find one anywhere?

TIA

If you pump them up and just drive it they will sort themselves out... or do you mean see how accurate the number is and change it if necessary?

More along the lines of 'If I wish to run different pressures' (Plus it actually threw a warning even though the indicated pressure hadn't in fact changed) :)

Ah ok, not sure on that. I would say the window of "ok" seems fairly large. I pumped mine up to full load for trip to Italy in summer, and the pressures have v slowly returned themselves to normal over the last 6 months or so with no issues TPMS wise. Id say you might have an issue if you wanted to run them softer than recommended (though not sure why you would want to?)

No real reason. More that every car I've owned with TPMS has an option (and apparently you can turn it off on the Ghibli)

Inflated everything on a garage air line just now. Highly odd (but probably nothing more than that) both offside wheels (which had triggered the TPMS) read 2.2 bar. Both nearside read 2.4 bar. Despite being inflated at the same time with the same airline and the same setting (2.3 bar) I'll let them cool down then adjust manually so they all match my AA pressure guage.

When TPMS is playing up, I always visit local tyre shop who have more accurately maintained gauges.
Having said that, I had a Peugeot 607 back in the day, great value car and underrated in many respects, but for 160,000 miles it had flat tyres (well according to the dash lights) in the end I gave up and the “black tape” came out.

I’m wondering if TPMS works on sudden loss of pressure maybe down to a certain threshold????
Mrs. 1963s SLK has a slow puncture and the TPMS doesn’t trigger any loss until it drops to around 1.5bar.

Mine doesn’t alarm till 27 psi, mine are 33 cold, rise to 37 after a few miles. In summer they can hit 40, no alarms.
