My present car came with Bridgstones. After 30 months I was glad to get rid of them because I found them noisy as hell and all four had developed uneven wear in the form of flats that made the noise intolerable. And vibrated the steering wheel.
Then I got Michelin Energy all round.
I check the pressures every two months. The Bridgstones almost never needed major pump ups just a few pounds to be as pernickity as possible
The Michelins need heaps of air every time . I've tightened the cores and always use caps but there really is a difference. Like all four last week needing circa 1.2 bar after 2 months .And I use an expensive gauge and my own pump.
Can different makes leak air at different rates?
Or am I ready for a tall chair and snakes and ladders every afternoon?

needing to add 1.2 Bar (18 or so psi) says two things.
1. you leave the pressure checks far too far apart
2. the roadholding and handling of your vehicle are probably dangerous and your insurance company would probably deny a claim based on this.
added to which
3. the probable cause is a poor seal between the rim and the tyre
4. some alloys can become porous

get a garage to pop the tyres off...the rims maybe corroded and need cleaning up , or if theyre not too bad they can paint on some sealant to make sure theyre air tight
|
Have the tyres removed and the barcodes attached to the bead area removed, the air loss will probablly stop ;o)

Agree about the level.
My dealer (or the maker and the dealer did not check during PDI) inflated the rear tyres of my Defender 110 to 90 pressure. 35, instead of 45 psi. Handling was really, really bad until I corrected it. I shudder to think what a bigger error would have been. (Yeah, I know handling and Defender are an oxymoron).
I assume corrosion of the bead area is not a point (can be with older steel wheels) but did you see them fitted? Normal to blow tyres up to rather more than the driving pressure to get the beads seating nicely, and then let them down to the right pressures.

>>Like all four last week needing circa1.2 bar after 2 months .
1.2 bar (17 psi) in 2 months (2 psi per week) isn't really that bad if you do a high mileage. All tyres are porous and the more miles you do the more air they will lose.
I'm just surprised that you've admitted to having driven for two months before you checked the pressures. The normal recommendation is once a week. Immediately prior to you checking them the pressure must only have been about 1 bar (14.5 psi), and that would have been dangerous ~ not just for yourself but also for all the other motorists around you.

Tyres, as lights, oils, fluids etc., are daily checks in my books.
Correct tyre pressures save lives as it means the tyre is able to do its tasks of: gripping the roads and stopping you more efficiently if it is inflated correctly.
They also save you monies when inflated correctly.
Unless you actually get down there (no good kicking them as you walk past) how else will you see if there is any tyre wall or tread damage? Never mind if there are any foreign objects (stones, bits of glass, nails and in your case possible: kids, cyclists, or other vehicles [SIC ] etc.,) stuck in the treads?
The OP clearly has no(?) regard for even his own safety and clearly absolutely none for those around him.
As L'escargot has already said, I too cannot believe you have admitted that you are so negligent in your safety checks.

Also, if you are in an RTA and the police attend they will almost certainly check tyre pressures and conditions of tyres too.
Any reason for your insurance company not to pay out will be taken by them....
....just hand them this one on a silver platter why don't you?

And that`s just the tyres, Tony ;);)
I have a spare set of leg irons and a Cilice in case you have not been checking your wiper blades.

If his tyres are that bad - what state is the vehicle in?
No. Leg Irons are an inconvenience and the Cilice is for people that are genuinely remorseful.
It is far too lenient because people like Tony are not only risking theirs but other innocent people?s lives too.
Ignorance or just plain lazy?
It is people like Tony that kill the likes of us that do make the effort and find the time a few mins each day (as well as spending the monies we do) ensuring our vehicles are safe to be on the roads.
Yep, sore point with me this one.
Rant over. I?m off to chant some mantra's for my own bad Karma in this message?

To be fair to Tony, he was used to Bridgestone tyres which he said lost very little pressure. New ones should be just as good, shouldn't they?
My guess would be that the rims were not cleaned up properly and/or sealant inadequately applied to the beads. My Continentals lose about 1psi a month (I check them every week or two) though the car only does around 9000 a year.

I think 99.99 per cent of drivers would fail the Tron safety test.
Daily, sir? If I get around that lot once a week I'm doing well.

A few thoughts on this:
The original poster said he had tyres checked every 2 months. I do mine at every fill-up, ie weekly. With a digital gauge cost me very little at the local spares place, but which I have had calibrated. Now, call me a pedant ("YOU'RE A PEDANT!") but I also get this gauge checked against a local truck tyre-fitter I know, who has his stuff calibrated every 6 months.
I often wonder how many of the forecourt pumps are calibrated EVER in their life? And for this you spend money... here it is a freebie!
I also wonder, when I do the long trips, how many morons have ANFC (Absolutely no clue) about their cars - they stop, after a 100km+ blast on the national road, and check their tyre pressure... AND THEN REDUCE IT TO SPEC!!!!
Accident waiting to happen.
