Outside tyre wear

Pilot sport tyres have made our car handle better again.
The oversteer is starting to wear the tyres, this is just from a weekend squirt.

Has anyone found a happy negative camber medium that suits daily driver.

Bit of how long is a piece of string. the camber is standard have been assured 0
For the driving we do, feel it is more wear than deserved.

Opinons appreciated Cheers

umm outside tyre wear means positive camber.

static negative camber might be 0 but as the outside wheels load up during a turn they experience a shearing force causing the rubber to 'roll" over meaning at the tyre surface there is more of a positive camber.

I have neg3degrees on the rear and neg1.5 on the front when I take my wheels off the car, the rear wheels stand up on there own (they are also 265wide hence the extra camber to fit them on my e46sedan) the front wheels however stand up with a exaggerated lean to the outside of the wheel, as there isn't enough front camber. I will rectify this soon enough I do about 18thousand km a year so tyre wear is important for me. I drive on the aggressive side so I would expect the wear to be more exaggerated for my setup but im happy enough with it

Ah....actually camber has nothing to do with outside tyre wear....! Its the toe angle that wears the inside edge or outside edge.

Outside edge wear is caused by too much toe in.....inside edge wear caused by too much toe out.....

so stanced cars with -10degree camber on the rear don't wear the inside of their tyres if they correct their toe?

yep, its not your camber..its your toe..
as long as your toe is set correctly, you shouldnt have worn inners or outers..that goes with stanced cars too^

OP.....for you car geometry for road driving will be perfect with -2 degrees at the front and -1.5 at the rear. As for toe front and rear should be .5mm toe in on each wheel.

ie total toe at the front 1mm in and same at the rear.

These settings will work for any e46.....even M3.

Just make sure you find a good place that knows how to adjust....99% of places do not have a clue!

^^^ These settings for the street is the best advise on here. Except .5mm toe out on the front and .5mm toe in on the rear each side for a 1mm overall
