That depends on whether they have a manual or automatic gearbox (amongst other variables).

About 3 years :wink: I had a similar problem with an XM, always pulled to the right, never suspected the tyres as it had a couple of new Goodyears on the front, once they wore out and I changed them - problem cured, so as suggested, try swapping them around.

So Update at last...

the third tyre centre that i took it to was Kwik Fit but they only had a "normal" tracking rig

after the suggestions on here to get the full geometry checked i called a different Kwik Fit who had one of these machines

they advised that the check was free. costs were only incurred if changes had to be made...seemed reasonable

when they checked the tracking was quite literally off the scale

they corrected the tracking and replaced two back tyres (which definitely needed doing) and revealed me of £150 (which i thought was reasonable for the work done and tyres)

and now it steers like it should do. the only thing i can think off is that the bushes were so worn that standing still everything checked out fine but under load everything was out of line. once i replaced the bushes everything was held out of line even standing still and once this was corrected it all lines up and works as it should

the thrust line check also shows my OSR wheel was running just a little bit out of alignment Kwik Fits Technician said it was too small to worry about and there was no way to adjust it anyway

guess what... four month later and i have just replaced the swinging arm bearings after i started getting that clacking sound that signals they are on the way out

so its taken a while (nearly 2yrs) to get everything right and i will never use the original tyre centre again

thanks guys for your suggestions i hope my final results helps someone in the future

Glad you got it sorted. It's astonishing how useful someone with a decent 4-wheel laser tracking rig is when they know how to use it.
