Can anyone please help with some thoughts on this...

My offside front tyre has a fairly deep shoulder groove worn into it.
This has developed over the past couple of weeks. There appears to be no obvious contact point within the wheel arch area. The nearside is not affected.

MY00 with eibachs and standard shocks.
New ALK and geometry.
New O-Z 17's with 215/50 Toyos.
I was running on 35 psi all around

Would my ALK have figured in a slight ride height change?
Dislocated spring?
Overinflation


The car drives perfectly as well.

Whats most likely then?

Thanks

I hope you meant 215/40/17? if you are running 215/50/17 then there is no wonder they are touching.

40 profile you're right JGM

hmm - one of mine did this , F/O/S if I remember (on Toyos). Suddenly found that 10mm of tyre had gone, almost to the fibre, within a couple of weeks...

You haven't just moved the rears to the front have you ?

Thanks Mark

Quite possibly. These are newly refurbished alloys and I recently washed and waxed them before nipping them back on.

How did you solve your problem? New tyres of a different flavour?

I am getting a free geo check tomorrow and if that's okay the plot will thicken and get more expensive

hmm - I actually had the geom done when the wheels and tyres were fitted - and this groove developed toward the end of life on the first set of tyres-

I had all 4 tyres replaced and its been OK since (not had the geom re-done, as it should still be set).

Did think about rotate rear->front last week, so that all 4 wear even, but the groove developed after I'd done this for the first time, so I don't think I'll bother - I usually replace 2 sets of fronts for each one of rears.

Also, same tyres (Toyos), though I'll be getting GSDs next.....

Incidentally, demon tweeks (who supplied the new tyres) said it was probably due to running on the inside rim (lots of camber) at speed. I wonder if running on the rear affects the inside of the tyre (i.e. inboard part) - which make the tyre wear oddly if then used in a different way (some sort of shearing created ?)
