Negative camber?

is this the normal sort of tyre ware on the rears? took my wheel of to change my fuel filter and found the tyre on the canvas on the inside and 3 to 4 mm left on the outside edge

no!

have a 4 wheel, wheel alingment carried out at a good garage (not sh1t fit!, or the like).

It is very normal when you have lowered the suspension. I have had a 4 wheel allignment, and the suspension is lowered some 4 cm. with a KONI kit. When I am only using the car for normal roads, the rear wheels looks like yours after 8000-10000 km.

Even with standard suspension the car is very hard on the rear tyres. In Germany the Alpine is called "Reifenfreser" which could be translated to tyre eater. When you drive on a track, you actually use the outer part of the tyre as well

after 10k miles on both my GTA's, one lowered and one standard, they have even tyre wear.

The rears shouldn't really wear like that no.

GTAs often wear more in the middle on the rears - Yokohamas were always particularly bad for this, my 17 inch Toyos wear nice and even though.

Yokohamas were always particularly bad for this

Often only 6000 miles life in these!

it's michelin's in the picture and its an A610 if that makes any difference

Yeah I remember. I was on first name terms with the boys down at the local tyre place.
The Toyos are much better - 12 to 15K miles I reckon on average. I've switched from T1S to T1Rs now which are meant to be even longer lasting so it'll be interesting to find out if it's true.

Remember you can't adjust camber on the GTA/s, A610...

Toe in can cause this, or worn bushes.

I have some upper rear wishbones available soon which will be available on an exchange basis, which will allow rear camber adjustment of upto +/- 5 degrees.

Is it just the one rear that's worn like this? If it's both it would suggest toe or bushes as David suggests.

If it's just the one then that's more worrying and it might be worth checking that the wishbone hasn't been damaged and bent slightly at some point. Whichever way an alignment check should shed some light on things.

To me that is excessive and abnormal tyre wear if it is right at the foot of the tyrewall.
Might be a big job, but if you took off the wishbones, they could be matched up back to back and you "may" find the problem, unless it is the chassis that they connect to, or the hub?
Does it look ok when the car is viewed at the rear from a distance?
Definately some measuring that up needs to be done.

o/s rear is slightly worse than the n/s rear,could it just be under inflation of the tyres?had a good look at all the wishbones and bushes and every thing looks ok how can it be the toe at the rear? subframe put in squint?? if it was the toe on the rear would it be the inside of both tyres??

think i need the upper camber adjustables now + 5 degrees might not be enough

Toe on the rear is adjusted by shims on the lower wishbones (and by the normal methods at the front)

That wear pattern looks like either camber or toe and since the camber shouldn't be out unless it's bent you've got to hope it's the latter. Get it checked and invest in a digital tyre pressure gauge - worth their weight in gold on a GTA or 610.

Toe in can cause this,

do you mean toe out?

inner edge worn......toe out

outer edge worn......toe in

That is the outer edge
