    Vehicle : Vauxhall

    Trim : Vectra SRi

    Engine : 2.2direct Z22YH

    Year : 2006

    Mileage : 54600

    Default Tracking issue???

    In order for my Vectra to pass it's MOT next week it's guna need 2 new front tyres as the current one's are near enough bold on the inner edges.

    Could this be due to the tracking being out???

    I got a 2006 SRi & it's still running on it's factory-fitted Goodyears & there is at least 3mm of tread left on all 4, but I know it won't pass coz of the inner edges on the fronts. The rear tyre's inner edges look ok. Mileage 32,200

    Righty, here goes

    It is always best to have the geometry checked, by way of a full four wheel alignment, when taking a new car that you plan to keep for some time (and will have new tyres fitted several times)

    The rear camber on the Vectra C is known to be an issue
    I was so concerned I sent one set of new tyres to Good Year for them to advise on, and it confirmed this
    This results in the wear you see, wearing out the inner edges

    As tyres are swapped any previous wear accelerates
    Hence why full four wheel alignment (camber and toe) is essential, and not just front wheel alignment (toe)

    Finally, when suspension components are replaced, if one fails then replace the other corresponding component on the other side
    On completion check for other components with play and/or wear, and once confirmed there are none perform another alignment check

    When the front tyres wear out, swap the rears to the front, fit the new tyres on the rear, and again perform another alignment check
    Note that in most cases the check will confirm no adjustment is required, however it is more likely after suspension component replacements

    With 3mm of tread remaining, this suggests the tyres have been swapped throughout the cars life, rather than leaving the fronts to wear out naturally
    Therefore the current front tyres are probably from the rear, hence the wear pattern
    The same will now happen to the current rear tyres
    As above, fit the new tyres on the rear, swap the old rears back to the front and have a full alignment check carried out
    When those front tyres wear out compare how those look

    I have just worn out a pair of front tyres, with the nearside shown excessive wear on the inside
    This was due to the failure of the nearside rear shock absorber which managed to pass an MoT and failed a few weeks later

    If tracking is out, as you suspect, then this normally gives uneven wear on both front tyres
    When the rear camber is out, the wear is more even on both tyres (more obvious when swapped from rear to front, accelerating that wear)

    Plus should you fit lowered springs after it's been done in the past this will need checking again.

    Took mine to vauxhall and let them do it as the fast fit places don't inspire me with confidence.!!

    Your toeing out on your tracking, causing wear on the inner edge.
    Fit new tyres on the front, as they steer and drive the car. Thus will wear quicker than the rear.

    Obviously tyres will wear out quicker on the front
    See previous posts for the reasons as to why new tyres should be fitted to the rear

    I do remember about 2 years ago I swopped the front & rear wheels around. When I get the front tyres replaced next week I shall ask them to swop them again so the new one's are on the rear. Should I of not swopped them then??? Could this of put the tracking out??

    When swapping tyres (simply for the purpose of swapping), swap them diagonally across the car
    Nearside front -> Offside rear
    Offside front -> Nearside rear
    Sounds to me like you just swapped front - rear

    The principle of fitting new tyres to the rear is two fold
    Firstly it puts the grip on the rear, as the rear tyres do not steer this is essential to prevent understeer and oversteer
    Secondly, it increases the overall average tread depth, if the fronts are down to 2mm the rears should still have at least 5mm (giving an average of at least 3.5mm)

    This will not cause the tracking to change, this is normally caused by impacting uneven road surfaces, kerbs, etc
    Also wear and tear, and replacing suspension component causes changes in the tracking (and camber)
    Hence, when fitting new tyres ALWAYS have at least the front wheel alignment checked, and if they advise adjustment is required decline this and take the car for a full four wheel alignment adjustment
    As previous, if the full four wheel alignment check has not been carried out, have that done irrespective

    These days and at least the past ten years the advice is to put new tyres to the rear till they bed in, However should you have 4x fitted you have no choice but to have 2x on the front & id much preffer new rubber on my steering wheels and just drive a little more carefull till they have bed in.

    I'd like to see the manufacturer that advises of that, certainly not seen any documents that mention "bedding in"
    Placement due to method of drive takes preference; FWD, RWD, AWD
