biased tyre

[splatspeed]

Vauxhall are claiming my tracking is going out so oftern due to a thing called a 'biased tyre' maybe

camskill have not heard of this

Avon tyres have not heard of this

is this a specific vauxhall technical term or has anyone else heard of it?????

[wildoliver]

It sounds a bit like service speak for "we don't know what it is so make a term up that will get rid of the problem customer"!

[agent006]

I assume it refers to the weight distribution of the tyre being off centre. I would imagine the term in the trade would be "shit tyre".

I seem to remember hearing the term 'biased belt' used, but I think this is just a reference to the direction of the chords and not implying any symmetry. If the suggestion has come from an ordinary working fitter who is not a tyre specialist then I'd be inclined to dismiss it as hogwash. If the tyre is causing it then either it's a design fault, or a manufacturing fault, or it is damaged or incorrectly fitted. Which of these are they suggesting is the cause, and why?

Its not an avon tyre is it?

[splatspeed]

yes it is an avon tyre

the tracking goes out on the car every 200 miles

and the car starts pulling left

they new think this might be a design feature of the monaro

that the car naturaly pulls to the left

and the steering ewheel should be off centre????

Tracking goes out as in the geometry changes measurably? I don't see how a tyre would cause that, more likely imo to be something that has happened when it is being driven - perhaps the vehicle gets driven up a curb or over a speed bump which is throwing the geometry out.

[splatspeed]

no i did thoose mile and i didnt collect a thing

there is something seriously wrong here they just cant find it

[wildoliver]

I have had a bad experience with Avon tyres, in my case it was ZZ1 (from memory) the tyre had very poor structural strength.

I went through 2 sets on warranty before replacing with goodyear, problem dissapeared straight away.

I think that what they are referring to is a belt separation on one side of the tread area, it won't cause the alignment geometry to go out, but it will cause a pull.

That sounds about right then

Can you move the dodgy tyre to the back and replace it with the back one (or spare) for a few hundred miles to see if the problem goes away?

[splatspeed]

they have ruled out the tyres

now and it is all fixed according to the main dealer

so i picked it up and it was improved

until i got near my home when the problem is starting to re apperar

so it was fixed for a grand total of 50 miles again

3rd time they have aligned the wheels third time the same problem has re occoured

vauxhall wont discuss the situation they are too busy

and they cant send someone to look at it as they are in newcastle for 3 weeks

23k for a car thatcant go in a straight line

[GreenV8S]

Since they did make the symptoms go away it seems that they know what's causing the problem. What was the 'fix' they made?

[mave]

OK, ignorant question here, how does the tracking actually go out? For the tracking to change, there must be something moving or something getting bent in the system, right? I can see that over thousands of miles you may get some shifting in certain components, but for tracking to change in 50 miles suggests that something's not done up right!

Just go to another Vauxhaul garage, you don't have to get warenty work done at the one you bought it at.
I'd get it checked at a tyre place, get it all set up straight and then mark all parts that could move/be adjusted with some paint then when it goes out again see whats changed.

unfortunatly with monaro

work can only be done at a monaro specialist

100 mile round trip minimum
