My rears went out in 10.000 miles. I know these cars eat out inner sides. Does this look normal to you?

The car has PSS10 suspension, wheel aligment was done in 2012 by a porsche specialized indy. The car has been handling very well. Massive traction when cornering.. Would you change alignment?

Alignment. Rear toe is wrong. The alignment probably had the tech really dial in the toe, why I have no idea. (This assumes of course the alignment was otherwise done properly, which is not (my experience) always the case.)

'course, to give the tech the benefit of the doubt, I have to wonder with the PSS10 setup that maybe the alignment can't be set optimally? In some cases aftermarket suspension components are needed to provide more range of adjustably than offered by the stock components.

Anyhow, I can get easy double 10K miles from my Turbo's rear tires and in one case got nearly 23K miles and the tires still had 3mm of tread left which meant the one with a nail in it was replaced free of charge thanks to road hazard coverage.

Correct toe should not affect the car's feel. Those times the car has had excessive rear toe as indicated by on one case rear tires that lasted barely 8K miles vs. those times the rear tires have lasted over double that number of miles I could not tell from the car's feel either before or after the alignment.

This picture shows previous rear tyres with OEM euro suspension. I cannot comment the aligment since this pic was taken shortly after I got the car. I think upper picture shows more even wear pattern than this one.

I will take my car to aligment tomorrow. I should ask them to tweak in the rear toe a bit.

Tire brand may play a role. This is Pilot Sport, my previous post Kumho Ecsta.

Send me your alignment sheet data. I will comment and forward PSS10 specs.

If you are wearing the inner 1" or so of the tire, than toe is your problem, not camber. I used to kill tires. One thing that I learned is that besides improved handling, my tire wear improved exponentially when I went to solid thrust arm bushings and mono ***** in the rear lower control arms. This prevented rear toe from moving around due to the compliance of the rubber bushings in the rear LCAs. The stock rubber bushing compress enough under load to allow up to 1/4" or so of fore and aft movement of the rear wheel assembly. That's a big number when translated to degrees of toe change....

Here's my tire wear in the rear. Perfectly even, no inner wear. -2.4º camber, 0º30' total toe. I think I've gotten about all I could out of 'em..

That's exactly how mine wear. I have X73.

Most I have seen wear the tires likewise. I believe powdrhound is correct about the bushings being a large part of it.

I thought you said you flip the tires on the wheels. You would get much more even wear this way or it this even wear with no flip?

powdrhound

I never said I flip tires on wheels. I flip the whole wheel/tire combo from side to side on the car thus rolling the tires the other direction. The tires I run are not directional but have an inside and outside to them.

jumper5836

So you does the inside edge on Left wheel become the outside edge on the right wheel?

powdrhound

NO. Outside edge stays the outside edge, inside edge stays inside edge.

jumper5836

so this is different then just swaping wheels side to side? I swap wheels side to side to prevent one sided use on certain tracks but never heard of what your doing?

Toe problem for sure.

The only way you can change tires side to side if you have non directional tires, most I have seen for these cars are directional.

I just replaced my old PS2s which were directional. The brand new PS2s now are only marked with "outside" so will work on either side of the car.
