    Just picking up on what Peters said...

    Last weekend, we were down in Edinburgh, driving back and taken the scenic route, which seems quicker (taking the Tay Bridge avoiding Perth), I picked up a screw in my rear tyre......
    Whilst driving I got the bong of death, so pulled over rather quickly and kicked the tyres, all looked good, so thought I’d check pressures, o/s rear down to 26psi.... having set tyre pressures a matter of days ago at 33psi
    Whilst checking tyres I noticed the screw, mid tyre between the treads, still shiny and almost gloating at the pain in the behind it caused!
    Being equipped with compressor and spare wheel got me out the preverbeil.... ( & latter went on to avoid running on flat & destroying an otherwise good tyre)

    Whilst not feeling confident to change at the side of road due to 70mph traffic, I opted to inflate tyre to 36psi, drive the short distance to allow turn off and changed wheel on some random strangers drive.......... (fortunately they were appeasing)
    So outwith the bags and on with the space saver spare wheel and a slow journey homewards raging at the thought of renewing an 8mm 315/35 R20 Bridgestone Rft......... fortunately tyre was removed and no sign of damage, so repaired.... had it been of lesser tread I’d not even consider repairing!

    However the point I was making, the old tried and tested methods still prove effective of pressure loss, the E70 has the Abs reluctor ring warning system, on this occassion it saved me dearly...... to the sum of £320! (Back in the pocket)
    But, I’d does ask the question how many of us do the honourable weekly/ monthly check, but do we reset and initiate the system after each check!

    Fortunately on this occasion I did!

    Glad to hear that you managed to get the puncture fixed OK. (y)

    Interested in your comment about the audible warning of the loss of tyre pressure. I had an instantaneous deflation of the front tyre a couple of weeks ago, but only noticed a warning notice on the iDrive screen. There was no audible warning at all, which I would have expected for safety reasons? That's on my F30 BTW.

    I've just checked the Internet and it appears that on the F30 the low pressure warning is only visual with a message on the iDrive screen and a yellow warning light on the instrument panel. There is no audible warning, which I think is a bit short sighted of BMW. If you happen to get a tyre blowout at high speed every second might count. :(

    I get an audible warning that is very loud and annoying.

    I check a minimum of once a month. I've got a nice PCL gauge/air gun on a portable compressor. So there is no excuse. Once the compressor is up to about 130PSI I can wheel it around both cars and eight tyres in about the same number of minutes.

    I keep forgetting to check my TPMS (surely my car has it?) but I have now put a reminder in my phone for tomorrow so will check. :)

    Apart from checking, how often is it actually necessary to inflate (or indeed deflate) the tyres?

    In day to day use both cars will retain the correct pressures for weeks or months. Although they will drop over time. If left standing for more than a week, the pressures will tend to drop more significantly. Although sometimes not. I too, have got into the habit of forgetting to reset the TPM on both cars. I must try harder.

    I check ever 3 weeks.

    On my wife's Nissan QQ the pressure never change seem to change , unless temp related in winter.

    On my X1 with rft occasionally I need to put 0.5bar in a tyre.

    The Z3 was in the habit of requiring 1.5-2 bar ever time in 2 of the tyres. I just considered this be sealing or leaks in the split rims.
    At the last MoT [which it passed OK] I had an Advisory ---valves perished DANGEROUS. Had all 4 valves replaced , they were
    cracked badly and not quite 2 tyres old. No more pressure reductions.

    I use this for a number of jobs including tyres

    I have something that plugs into the 12V for use on the road.

    Over the years I've spent a lot of cumulative money on electric tyre inflators. I've never found a good one that lasted more than 2 years and have sometimes been tempted to go back to foot pumping.

    Since I went for the heavy duty equipment 2.5 years ago, checking my pressures has been quick, easy and consistent. And my expenditure on gauges and pumps has been zero. The longest ever hassle free interval.

    I have one of these portable compressors by Slime which I've used for motorcycle journeys, but it's not that suitable for car tyres because it would take so long to inflate. But it does pump up to 300 psig.

    https://www.ebay.co.uk/itm/SLIME-40...801560&hash=item3f995e6fbe:g:-4wAAOSwl-5a0rNP

    For the car i have a small Broom and Wade 1 cfm compressor in the garage c/w airline and tyre inflator etc. Also have a couple of spray guns that I've used in years gone by.

    I use a foot pump as my Continental compressor is not really up to the job on 21" wheels.

    I would say that your car will have the Indirect tyre Pressure Monitoring Systems, they work using the ABS wheel speed sensors, as the tyre goes down the diameter changes and the sensors pick up the difference and alert the driver

    if it is this system that is used by your car you wont have the pressure readings for each wheel so i would say that you should be checking and adjusting pressures on a regular basis, now what is a regular basis i drive a fleet vehicle at work and we are told to check the tyre pressures once a week and due to the fact that the vehicle is doing 500 miles plus a week this is not unreasonable

    Well Harry’s compressor and tank puts my Michelin compressor to shame
    However for some time I’ve thought of a similar set up, will be handy for the air gun and various power tools from my workshop days, (1/2” 3/8” Air gun, drill, blower sander)
    More than likely, I’ll pull them out the shed and they’ll all be seized.....
    Seed is plated now though, so next I’ll have to acquire the compressor and hose...
    First things first though and that’ll be a nozzle for the pressure washer to preserve its life!

    I think @Merc? No. BM! would have TPMS as it’s a 2014 model year car.

    I thought it was a bit earlier than a 2014 model year car

    A compressor comes in handy for all sorts of jobs. I'm lucky because I have a good size shed with power. Been planning it for years and I might live long enough to get some good use out of it!

    Yes and still grateful for that Ian (y)

    Apart from my slight niggle with the (lack of) soft stopping, so far the car has been flawless and I still smile every time I sit myself down in it and drive it!
