Tyre inflation inflation!

The big difference of course is that I know how my pressure gauge has been treated.
I know it's not been dropped onto the concrete from waist-height or above. I know it's not been run over.
It simply sits quietly into the garage most of the time, minding its own business.

Although being treated well doesn't mean it's accurate, however you get yours calibrated, right?

No.

Nor do I correct the pressures for temperature.

Naughty me.

Its just a guess at the end of the day then, there or thereabouts, no better or worse than the garage pump then, which was probably more accurate when new and also get serviced and checked

Ah the joys of TPMS on your car...
Just drive, look at the pressure on each wheel & you can correct if needed. Yet to find any change after 4 months

That £11 on a pump was not very MSE....🤣 Neither would be going to a garage to check.

Does TPMS actually give you the pressure, or simply green / amber / red indication?

Is the cost of a new car with built-in TPMS more or less than the £11 pump?

No change in pressures in 4 months?
None?
You sure it's working, as I'd expect some variation in 4 months.

I don't know why you'd think the garage is inherently more accurate when new, presumably assumption based on the fact it's an industrial product rather than a domestic one?
For me, the problem with garage ones is the inherent problem that you've to drive to one and pressures should be checked cold.

Different TPMS do different things. Some give you pressure on each tyre in numbers, some give you colour-codes, some simply throw an error if the rotation speed of a wheel is different to what's expected.

The "direct" systems that measure pressure often require new senders fitting and coding-in with tyre changes.
The "indirect" ones simply use the ABS sensors.

It's nearly seven years since all new cars had to have TPMS fitted...

I last checked my pressures on the 27th Feb. I know this as the power to the street was turned off for 4 hours and with nothing else to do I went out and did a little maintenance on the car. 

The TPMS on my car you set it to what ever pressures you want. It does work as I was alerted when I had a slow puncture. Not sure it pings when it goes down by just one PSI though.
