    Hi all.

    Has anyone had some experiance with a problem like this.....

    Ok just before i bought my car it had a pair of rear wheel bearings as a recall from Vauxhall, aprox 18 months down the road my car has developed a noise that could be very bad road noise or a wheel bearing on its way out (can’t hear it under 20 but gets louder as you get faster). I have had a look at the rear brakes and they seem fine and the bearings seem to be in good order (don't make any noise when the wheel is spun off the ground and no movement).

    So after some reading up and searching i have come to the conclusion it must be some thing to do with the tyres, so i have just put 35psi in them to see if it made any difference to the 28 i usually put in and the noise has got louder.

    So assuming that this is a tyre problem? and the tyres are not directional (i'll have to check) will it make any difference swapping the sides? so they are effectively running the other way?

    id swap them front to back,if they have been on for awhile doing it the otherway,will scrub the tread off quickly,jack it up and spin the back wheels look at the tyre,is it moveing up and down?best way to check is on a balence machine,might be better off just putting new rubber on there

    the other thing is i have tried throwing it about to move the load from side to side and it doesn't make any diffrnce?

    i have to admit i am seriously thinking of just sticking some new rubber on but i might swap them front to back just too see if the noise moves or goes then i'll be happy its 100% not the bearings.

    are tyre problems common on Vecta C's? there seems to be alot of people pointing towards tyres? i thought there was a big recall because of bad rear wheel bearings?

    Highly likely to be the tyres - there's a long running poll over on vectra-c.com where 70% of the respondents found that this noise was coming from worn tyres, not the bearings or any suspension parts. If it's been happening for a while, then it will have left visible marks on the rear tyres - look for uneven wear on the inside edge of the tread on each tyre.

    TBH i don't know much about tyres, i have taken some pics of one (the other is exactly the same wear) i think there is some inner edge wear but i wouldn't expect the volume of noise to be produced from it??

    Difficult to tell from those pix....if your fronts are in better condition, swap them over to the back to see if the noise disappears.

    well i have just dropped the tyre pressure to 24psi in the rears and the noise is quite alot better so i'm guessing its going to be tyre time....

    Don't keep it at 24 PSI though, as it's pretty low.

    there is quite a bit of inner edge wear on them ,look at the flukes on the outer blocks to the ones on the inner,the inner ones are worn,bet the tyres are cone shape when removed:ROFLMAO:
