Hi all,

I am experiencing with my 6 months old Volvo 40 factory fitted summer tyres (205 55 R16 on Mannan) significant drops of pressure on monthly basis. E.g. from 2,3 bar to even 2,0 in a quite short time period (does not depend on the atmosphere temp). On my previously owned cars pressure was stable even for the whole season. Does anybody have similar experience?

In addition when I inflate tires to 2.3 bar, car gets very firm and I can feel each pit and bump, followed by rattle from front suspensions. When pressure drops to 2,2 or 2,1 car is much softer and there is no rattle anymore. But manual says 2,3 bar....:huh:

Br,

Hi Ludilo,

Does the tyre pressure drop affect all four tyres and if so is the pressure drop even across all four tyres?

 

[Ludilo]

Drop is on all four tyres, but more on front tyres.

I can't say I have really paid that much attention to the the pressures. I just check mine regularly and I think they have all have remained pretty even pressure wise.

Check my tyres on a Sunday morning, Never had any loss of pressure in the 7 months I have had it.

Never had a problem with losing tyre pressure. Checked regularly but always close to what they were a few weeks previously. Can't imagine why you are having a problem, but firstly I would go to a garage and inflate them to around 4 - 5 bar, then let the pressure back to 2.3. May close a leak in the seal between tyre and wheel.

When I first had mine I had a significant pressure loss in one wheel. Turned-out to be a fracture in the alloy. New Ixion supplied and since then have had almost no loss at all.

My Michelin's will need changing soon (18k now). A chap I was talking to in the pub mentioned that his Passat was much quieter after he had some German tyres fitted by a place called 'Supertyres'. He didn't have the car with him and couldn't remember the brand but can anyone enlighten me please?

The tyre noise on ordinary roads is the one thing that gets me down in the Lovely V.

differences in tire noise vary massively between brand and even between types of the same brand. I used to drive Michelin energy's on my old V50. They are rockhard and stay good forever and ever. However they almost make a clattering noise. Switched to some Goodyears (dont ask which type, too long ago) and the difference was night and day. Most tire tests have road noise as one of the criteria, so just look those up.
