uneven tyre wear

[wilsonian]

OK so I'm still getting uneven tyre wear on my car.

The inside of the drivers side is wearing quicker than other edges.

In the past (last 12 months) I have replaced the following items (on both sides):

Console Bushes (Power flex std ones) front and back.

Drop Links

Wishbone & Ball Joints

Track rod ends

I've also had Awesome GTI do the tracking as I felt the cheaper national garage might not be doing a "proper" job. They found nothing strange.

I replaced the fronts with part worns after I did the track rod ends but recently have noticed the inside of the drivers side wearing quicker than others.

Does anyone have any other suggestions? I'm pretty stuck as to what else could be causing this.

Thanks.

tracking was done after all the parts were changed?

is the car lowered? if so was camber / caster altered to suit?

[Steve Neate]

Can you describe the nature of the uneven wear?

Are you running the correct pressures?

The tracking was done a day after the track rod ends were replaced and a few days later I had the tyres replaced. Also the car isn't lowered.

I'll post a pic of the wear tomorrow and AFAIK the tyre pressure is around 34psi for the front.

Should be 2.3 bar at the front.

So around 33psi.

[Kevin_Mc]

I stick with 36 in the fronts and 35 psi in the rears and even then they look like they could do with a bit more

[MattH]

That's more than is recommended.

Skoda state 2.2 bar rear & 2.3 bar front.

Just a note my wheels are 17" Spiders and I run 17/40/215 - I take it the pressure doesn't change?

Did Awesome do a tracking check or a full geometry? (full geometry will include toe, camber and caster angles front and rear, rear axle thrust angle, and possibly more).

[wilsonian]

I beleive they did a full geometry check. At the time the car was still running on the worn tyres but only did so for another 2 days (once I got the part worns on).

Also AFAIK you can't change the the rear of a fabia as it's a fixed axel (acording to awesome)...

You can't change it, but if you bend it you can get a mis-algned chassis. If you've still got the results, put them all up and we might be able to tell what's wrong.

the rear geometry can be changed using shims like these ones

although if the car has been jacked on the beam and its bent your pretty much ******

Yes, but to add what others have written on this "feature", the aim of getting a full four wheel alignment check/adjust, is to get the car to run true, and that means centring the front wheels to the rear ones. Minor (invisable) body damage would stop this being achievable, ie this or many other reasons could stop you having four correctly aligned and to themselves, wheels. Any slight normally acceptable misalignment could with wider stiffer tyres show up as uneven tyre wear.
