Title: Front tyres wearing on inside, the problem is not chamber or wheel alinement
Post by: sax-p on 03 March 2013, 19:39:00

Hello,

I would like to find out the problem of my two front tyres being ATE away on the inside before I fit the new 17's,  I have the wheel alinement done, that's not the problem, no chamber, it's  only after happening since I changed both wishbone with new ones, pics of wheel that came off  :(

Any help I will appreciate, as I don't want to fit the mv6 wheels with new tyres until I sort this, right now I'm rolling 3 steel wheels and a gls wheel  :'(

Thanks
Trev

What is the current camber setting? What was the old camber setting?

That hasn't happened over night. What time scale are we talking about?

I know you say its not camber, sax-p, but that is classic camber fault.

Have the subframe bushes been changed?

Does the car sit right visually. Not low or lopsided at the back?

Did the Wim franchise complain the rear track rods where seized, and they couldn't adjust it?

The problem is camber and wheel alignment will not detect that. The OEM setting for the camber is -1 degree 40' +- 45', this means the front camber position could be -2 degrees 25' and deemed as ok, it's not! An unladen position of -1 degree 10' seems to work best historically.

Looks like I will be getting the car fully checked over by someone who has all the right equipment, the last fella I got to do it said everything was perfect, looks like his is wrong,

Thanks all for the help

Omega needs full geometric set up, for castor, camber and toe at the front. Camber/toe combined via rear track rods. I missed the fact :-[ it had only been set for wheel alignment, which is toe only. Not even half the job.


Still, those tyres are nearly done anyway.
