Weird Tyre Wear

[Mr K]

i am getting weird tyre wear on the front of my 1.9TDI A4 saloon (2wd) with sports wheels and suspension (16s, with 205 55 R16 Khumos on the front, and the std pirellis on the rear.)

when i got it the front two tyres were getting low on the outside edge, so i replaced them, with the intention of doing wheel alignment after i did the top arms... however it was clear after 5k miles that it was chewing through my new tyres! down to about 2-3mm on the outside edge!

so it went in for wheel allignemnt with only new top arms on the drivers side... they said it should all be tip top....

5k miles later and its clearly not. the inside edge of the driver side front wheel has no tread left on about 10mm of the edge! the passenger side is showing some signs of this same wear, but nothing much.

is this likly to be somthing to do with only doing the two top arms? im running 32psi all round as per the filler cap, as its usually only me in the car.

i appreciate the khumo is a soft tyre, but this is very un even wear!

what tyre pressures is everyone else running?

2nd opinion with the wheel allignment i would say just to be sure.

Was the car bought used?

Its just that the car could of cracked a kerb or similar by a previous owner. I was looking at a car from a trader once and the tracking was not right, it had to go to a main dealer with specialist tracking machine, think its called a Hunter and there are other makes. There are a few specialists and dealers that have them dotted around the country.

In short, what Markey said!

 

[Mr K]

OK cool, there is a good chance its been knocked out by the previous owner, although there is no curbing or damage on any of the alloys.

any idea what audi / volkswagen would charge to do wheel allignment? properly.

 

[Bong Water]

Normal hourly labour rate I think, not all dealers have alignment machines but the ones that do are trained on them usually. Unlike my local ATS who have a machine and no one that knows how to use it!

Basically its best to phone, see if they have one and get a price

 

[Mr K]

made a few calls, and on saturday i will be taking it into mitcheldever tyres who will check it, adjust toe in / out, and give me a print out. if it needs camber or caster i need to book it in during the week. £27 and they have decent kit.

atleast this time im getting a print out so i can see for my self that its right.

i read somewhere that to adjust the camber you have to move the engine cradle using a special tool? is this true? i presume only audi can do this?
