    Just after getting this gorgeous E320 210 Rust bucket, in mid 2015 and after meeting up with Malcolm at a gtg in MB World some time after and sadly for the last time - he recommended to me to only keep the tyres @ 30 psi all round to get the best mpg - which i did and largely he was right.

    However after grounding out too often on road humps that are in abundance down here in Sussex / Surrey I have raised that to 35 all round, which has stopped a lot of it paticularly on the front that has to support that heavy lump of an engine.

    So any input or personal preferences please, would be gratefully received.

    Wheels are 215/55 R 16 Basic alloys which I'm very happy with as they're the cheapest tyres out there which gives me confidence to jump kerbs without too much concern in tight spaces etc.

    The lower the profile the more important it is.
    I do check mine more frequently than previous cars even with the tyre pressure warning system.
    The tank flap gives a starting point, after that its the feel of the performance/ride and then re-assess after seeing how the tyres wear. What suits one person wont be the same for all as it depends on weight carried in the car and expected journey speed, e.g. town or motorway driving.

    How frequently please - every fortnight like me, but then I'm only doing a couple hundred miles a week.

    It varies, my car lives in the garage and only usually comes out at the weekend. I'd say it gets checked every few drives out but I would always check before a long drive and always give the tyres an eye before a drive when I don't check with a gauge.
    Mine are 17" wheels and the fronts need a good eye kept on them, 16's will be more forgiving and wheels with rubber bands need to be just right at all times.

    I'm probably checking every 2/3 months. Tend to work on 32psi all round ish .

    ^ as above, but then I’ve the TPMS with actual values too which I check every couple of days.

    The novelty wears off quickly, so not too often, unless I fancy a play with an iPhone app:

    Every week or so. Just check the onboard computer though to see if they match what it wants...

    32psi all round on the 210 unless travelling to France where its 36/42 because its normally filled to the roof with stuff. Check them monthly on average.

    The correct answer is...everytime I go out first time that day. But, I'm not a police driver so...when I remember.

    I said above every 2-3 months , but also every time I'm due a long journey , along with oil and washer fluid .

    I will know if tyres are likely to lose pressure, mine don't Larisa's do (until I have the wheels refurbed' hopefully).
    So Larisa's get topped up more often and before any significant journey.

    Otherwise I check and adjust as the seasons change and temperature is likely to be changing for longer than a short lived fluctuation.

    As above I start at the recommended pressures but check the wear at 3 points across each tyre regularly. From that I can see uneven wear due to incorrect pressure and then make allowance to compensate.
    I don't have a specific interval for checking.

    Our car has those sensors that let you know when the pressure is down and we seem to get an indicator every couple of months for one of the front tyres. If we didn't have the sensors I'm really not sure how often we would actually check them and quite honestly I don't even know how to, so it's a good job the car does it for us ;)

    How often can depend on the tyre make as well. The original Conti's on the B class would drop from 35 to 30psi in a week while the replacement Yokohama's drop from 35 to 32 in a month, while the Bridgestone's on the Tiguan go from 35 to 33 in 2 months (and I always check under the same conditions, so they are comparable).

    My recommended are 32 rear, 29 front, but i run 33/30 as on 32/29 they don't wear correctly.

    Interesting that you think you can see the difference in 1 psi. Begs the question - how do you know how accurate your gauge is?

    As we can't realistically calibrate these unreliable devices I put my trust in a hand held gauge kept in the centre cubby.
    If it's out it doesn't matter as monitoring for uneven wear means eventually getting the right pressure according to that gauge.

    Aye. My guage may well be out, and perhaps the true reading is 32/29, but as long as I use the same guage all the time I can calibrate the change I make.

    Forgive me, but that seems improbable. I've owned 50+ cars in almost 60 years of motoring and check my tyre pressures approx. fortnightly. I have never had a car on which all the tyres lost pressure equally as you describe yours - there has always been some variability between wheels, generally same tyres fitted all round at same time.

    As to the main discussion, I just don't get why you would deviate from the manufacturer's recommendations - unless your backside is as sensitive as Lewis Hamilton's, you won't notice a few pounds either way, so be guided by the experts!
