i got a question bout tire wear. right now i got the OEM Yokohamas on my 06 Evo 9. The inside tread of my tires is wearing real fast, but the middle and outside are normal. It is on all tires, but mostly on the front. I called a dealership in St Louis. they say it is normal for the car, but is it? should i get a alignment. I only got 5045 miles, mostly on highway. thanks for any help. you can PM or post here

 

normal for any car that handles well, i rotate every 3K with the oil change

 

Negative camber is causing that wear. The car is setup to run around 1 degree from the factory but by adjusting the camber bolt you can get 2 degrees out of it.

How often did you rotate your tires? You should rotate them religiously since they are soft and stuff like this will show up quicker with these then a standard tire.

 

The factory alignment is hit or miss. And they miss a lot. I had cords showing at 6K miles on the inner edges due to wacked alignment from the factory.

 

i know it is newbie question, but when you rotate your tires, do you switch sides on bqack and move forward, and then move fornt straight back? i never owned a AWD before

 

It depends on if you have directional or side specific tires.

If they are directional you can rotate once front to back then next one they need to be swapped off the rim and positioned so they can go the right direction and installed on the opposite side of the car.

If they are side dependant you can only go back and forth and will not help with the camber issue.

 

im yet to get n alightnment or a tire rotation,

can anyone recommend a place to do these?

 

I've got the same phenomenon right now. The insides of the tires are worn, but not the outer or middle. For those of us using the evo as our daily driver, is there any real detriment to dailing out the negative camber? And if you can, how's it done?

 

not to revive a thread but i have the same issue at 7k.. i heard its for better handling.. but im about to put new rims and tires and dont feel like tearing them up that fast.. will i sacfrice that much handling to set the camber straight?

 

It also depends on what your doing with the car. I am putting on some new falken 615's and when they start to show a fair amount of wear I will flip them and run them backwards considering that I wont need the wet traction durring the summer time, and it will allow me to run a more aggressive alignment.

 

Don't worry about the camber settings so much. Worry about the toe settings. Too much toe or uneven toe is what kills tires quickly. And if you have a lot of negative camber too, it kills just the inside edge of the tire really quickly.

A good target for a street/daily driver alignment IMHO would be -1.0 deg camber all around, 0 toe in front, and maybe 1/8" total toe in in the rear for some safety or 0 toe in the rear if you are feeling adventurous.

 

You know, I had 11k on my car and mine are completely worn out in the exact same you described your tires. I've rotated my tires at around 5.5k miles. As soon as i saw it I figured it was my alignment and i took it into a shop to have it checked and needless to say they were all way out of whack. I don't have the specific numbers but all four tires were off which was a bit strange. I got it fixed and noticed two things, the shifting is a lot smoother now, and my brakes are no longer squeaking on light braking.

 

What effects on handling will 0 toe have compared to negative toe?

 

You either have toe in or toe out. Toe in gives you a little more stability, toe out make the car turn better (can be dangerous with unpredictable snap-oversteer). In both cases your tires will wear out quickly.

0 toe will help your tire last longer. Negative camber (during straight line driving) puts most of the pressure on the inside of the tires but it is toe that wears them out faster. Negative camber actually helps balance out the wear of the tire for more aggressive drivers ... on stock suspension my problem is actually the opposite, I wear out my outside much faster than the insides.

 

So 0 toe with -1 camber in the front and rear would be would be a safe bet for the street?
