who has rear tire scalloping/feathering/cupping problems?

[euRo_tuner]

tire wear similar to this..

it is happening on the inside of the rear tires..

at first i thought it was toe issues... but now ive heard its due to possibly suspension components.. tried to get my car on the alignment rack at my school.. failed miserably.. way too low for the rack.. even with bumper offf.

any suggestions or things to look at? im on fk powertec coils.. alll the way down in the back.. firmess is on like 4.. out 6. 6 being full stiff.

i noticed this when i rotated my tires...i got an alignment right after but the guy told me the rear cant really be fixed, kinda sux but i guess we gotta live with it

A. lack of rotation
B. bad shocks/strut

staggered

doesnt seem like the shocks are bad.. they arent bouncy at all..

Check your air pressure. Driving an under inflated tire will do the exact same thing.

[euRo_tuner]

i will..

but underinflation will cause outside wear on both inner and outter..

in my case, its just inner.

Possible bent axle?

every set of tires i've had has made noise, never noticed anything this bad though..

Lowering the rear of a MKIV=negative camber=inner tire wear. You can get some camber shims to correct it, raise it back up, or just deal with it like everyone else with a lowered MKIV.

Car looks sick btw

Because we don't have independent rears, there isn't much adjustment available for us and due to the way our axle moves when being low it throws the wheels out of alignment. You could try and use shims but since there's no way to measure it if you cant get it on an alignment rack it will be a big guessing game.

Every dub I've ever had has done this.

Rotating the tires with every oil change prevents it from happening, but my experience is that once it happens, you can't get rid of it.

It's a real PIA. I wonder if the Mark V does this since they went to multi-link rear suspension.

[xXSLVR6Xx]

the car is lowered so you have more neg. camber then the stock setup, its gonna happen unless you correct the camber somehow.

[spitfire481]

its a solid beam. camber wont change throughout travel

[DJP944]

individual toe is not adjustable in the rear. the only thing you could do is shift the whole beem and adjust the total toe. as far as camber is concerned, you shim it to adjust

could this cause the steering wheel to shake? i just rotated my rear tires to the front and front tires to the rear. I noticed this inside "cupping" or uneven wear when i took them off. i rebalanced the tires and got an alignment but the shake is still there, anyone?

Swap each wheel for a steelie you know is balanced correctly and try them.

If that doesn't work you probably have a bent or unbalanced axel.

i would imagine the rebalance won't help much, the rubber itself is worn into a pattern that would shake the wheel.

Wouldn't a bent rear beam cause uneven wear?
