Weird tire wear. Not like normal camber wear

[aimre]

What would cause this weird tire wear. is like 2cm wide, with a very straight edge. Looks like this pic i made

inside or outside?

[turtleEK1]

Has your car been lowered or mods done? When you turn full lock does your tyre hit anywhere? Either the fender, the chassis or even control arms?

[driftincivic]

flat spot caused by hand brakies lol

[EKVTIR-T]

As turtle said.Looks to be from inner or outer guard rubbing.

[omgzilla]

What tyre is it (Front/Rear/Left/Right)?

[Euro08Jaz]

this threads getting a little dusty but id say oversteer wear, my left front Tyre looks exactly the same.

um.. whats that??

if a car is oversteering then it's 'drifting' and isn't directly relevant to a specific tyre wear

[Limbo]

rubbing from hard turning?

[dwn_boi]

maybe you need a wheel alignment? i had similar tread wear too, caused by wheel being knocked a lil out of alignment from big pot hole

[rpm boy]

Your tyre is hitting something on your inside fender, had the same thing on my car, itll take a big semicircle chuck all roung your tyre out, just take your tyre off and u will see that there will be a bump on your inner fender that will be silver instead of your car colour cause your tyre has worn away the paint

bluh! sorry i meant understeer lol

looks like heavy camber wear. mines about the same.
outside is almost perfect.

[string]

Rubbing on guard, spring, inner fender wall - no alignment problem will cause such irregularities and angles in the tread.

had this in my old ek and was due to toe in and negative camber concentrating all the wear to the very inner edge. does it have feathering? see on mine how the very edge was almost bald yet the 2 cm in it is finehttp://memimage.cardomain.com/member_images/12/web/2436000-2436999/2436055_109_full.jpg

my body side of the lca bush was buggered so the lca slide back making it toe in on that wheel and because of the camber cause the inner edge of the tyre to scub wearing it down in no time on the corner of the tyre.

Is that a front tyre? If so then IMO it's most probably wearing on that edge when that tyre is on the inside of a corner with steering angle applied and some body roll occuring.

Contributing factors will be:
Static neg camber;
will cause the IF to be more loaded on the inner parts of the contact patch (more so with more neg camber).

Body roll;
will cause an increase in IF camber, which will run more on the inner tread edge as body rolls.

Insufficient caster angle;
caster angle causes both front wheels to change camber as they're steered, with the OF gaining additional neg camber, and the IF gaining steered pos camber. This affect counteracts (in some degree) any IF static neg camber and camber change caused by body roll, assisting to keep the IF tread in better contact with the road surface (i.e. larger, 'flatter' contact patch). Not enough caster angle accompanied by significant static neg camber and body roll, and the IF can easily be running on it's inner edge when cornering.

Ackerman angle;
causes the IF to be steered more than the OF, i.e. creates a very substantial amount of steered toe-out, which is normal to account for the different corner radii encountered by each front wheel (in theory). However, Ackermann effect is only more or less correct at X steering input. i.e. the Ackerman angle needed for perfect Ackermann effect changes with changes in steering angle (and with different degrees of weight transfer), so it's rarely ever 'correct'. So, much of the time there is a significant degree of steered toe that is causing scrubbing at the contact patches (despite the Ackermann affects attempt to counteract this).

So, when cornering, we may have a situation whereby the IF is often only partially unloaded (due to moderate weight transfer at the front relative to the rear), is running on it's inner edge because of static camber + any camber caused by body roll, and where there may be a lack of significant countervailing caster affect. We may also have substantial steered toe-out (i.e. incorrect Ackermann), so the IF contact patch is not only tiny, but is also being scrubbed along the road surface.

FWIW, my advice would be (in no partricular order) :

Increase roll stiffness in order to lessen roll angle.

Increase caster angle.

Decrease static neg camber.

[OMG.JAI xD]

im guessing you have a lowered car and havent done a wheel alignment.

lowering car causes more negative camber if a camber kit isnt applied.
at the same time the previous toe in toe out adjustments go out of whack even more.

that to me. looks like negative camber plus heaps of toe out on that tyre.
get wheel alignment checkd out.
