Premature tire wear

[AndrewBird]

Camber isn't the only thing that causes inside wear. Toe will do the same at a much higher rate.

[gte175x]

my guess is worn springs/shocks and perhaps a cracked rear subframe - sloppy bushings is probable, but I'm not sure they would make the rear squat as much to affect the camber....but then again, your camber could have been out of spec too. gotta get it up in the air to inspect

Do you drive the car hard? Those tires have a really shitty tread life, I can say that from experience. Very grippy on dry, but wear down in about a year or so.

I had them on my E46

why don't you bring it to an alignment shop instead of guessing? or listen to everyone's random guesses here, 95% of which are likely wrong?

i just noticed the same thing on my front wheels, I think my control arm bushings are toast.

[Wschnitz]

why was this bumped lol

When you replace the bushings get the weld in camber and toe kit. I have eccentric adjusters and all new oem bushings and after 10k miles on Dunlop star specs they still have about 60-70% life left. I drive the car fairly hard and spin the tires at least once a week.

There might be two different versions with different treadwear rating, but I believe mine was rated at 65,000mi. I put them on and drove it like a go kart for a year and they wore down by the 2nd year. No where close to 60k was put on those tires. I find it hard not to take corners a little faster than normal with stiff suspension :p

no warranty?

Really? They are rated to 85 thousand miles. Mine are still good after 2 years.

Could be a toe problem.

x2 on subframe bushings.

Since there is no adjustment on camber from the factory, this usually comes down to slop in the bushings causing your rear suspension geometry to be out of spec under load. That does look a little extreme so I would be concerned about a bent trailing arm.

Once a tire wear pattern is established, it is there for the life of the tire. In addition, the tires you are running will wear more quickly at extreme angles. If you don't do the bushings before you get new tires, make sure you rotate very frequently. It won't fix the problem but it will help.

I sure hope they get more miles than that, I put mine on in March and have got about 3k miles on them.

no but the camber kit can fix bent trailing arms. nearly every e30 i've ever seen has had at least 1 bent trailing arm, if not both.

i've seen the weld on camber adjustment kits before but my car is stock... One would assume the car wasn't cambered out from the factory
