Tyre inflation inflation!

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

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

So, yes, then - can't get a car <7 yo for < £11

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 

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.

Yes I would say that an industrial product is more accurate both initially and over time compared to an £11 domestic model

The "direct" systems that measure pressure often require new senders fitting and coding-in with tyre changes.

For the record, we had direct systems in our Kia Sportage and our current Evoque.
The Kia went through summer/winter/summer tyre changes for its three years with us, no new senders or coding
The Evoque has had three new tyres in the past month (don't ask...) and, again, no new senders or coding.

"All cars newer than 7yo do" is not the same as "no cars older than 7yo do", of course.

Fair point, the question still stands - can I get a new (to me) car with TPMS for < £11?  
Or even after-market TPMS to fit to an existing car for < £11?

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?

Pressure on each wheel.

When did TPMS become mandatory UK?

This was broadened out in November 2014 to include every new passenger vehicle being required to have a TPMS before being sold.

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

Yep.
Each wheel went  from 36 PSI to 40 PSI on a 200 mile trip last week 👍

I can't remember the last time I had to put any air in a tyre.

I have to top mine up about once a year, typically late autumn when the weather gets colder and causing a corresponding reduction in pressure.

However, my £34 pressure gauge and pump reads 0.2 bar more than the TPMS in the car. It’s always been that way, since both were new. Clearly one of them isn’t accurate but I don’t know which.

The basic tpms only shows a puncture by the wheel spinning faster, no pressure is shown, and no wheel is displayed, you have to check each wheel, its quite crude and the tyre has to lose quite a bit of pressure before it shows. Of course front wheels will spin at different speeds if you go round corners when the diff comes into play. Dont understand how some people only need air once a year., as even a new car kept in a garage low mileage needs more than that.
