Suspension/tires causing tracking issues
This has been going on with my car for a long time. Ever since I upgraded to 18x8 rims with 225/40/r18's and lowered it on H&R springs, the car wanders all over the place. It's super annoying.
It's especially bad on the freeway and where ever there are ruts in the road. I used to drive a Jeep Wrangler that was lifted with big tires (ha ha, its funny to go from a red-neck car to a mercedes), so I was very used to this.
I have always assumed that it's just a drawback of going with wider rims. My thought has always been that it's a leverage issue- the wheels/tires are wider, which causes leverage against the steering components when I go over ruts. That the wider wheels make the car easier to be steered all over the place (is steered a word?).
For those of you who have wider wheels installed on your cars, is this an issue for you? My car certainly did not do this when it was riding on the stock wheels/tires.
One more bit of info, I had a full alignment done by the shop that lowered my car. However, my tires are wearing prematurely in both the front and the rear. I know that I need to get a camber kit for the rear eventually, but my understanding is that the front is adjustable enough that you can get it back to within spec without modification. However, the fronts are still wearing on the inside edges more than the outer edges. So maybe that's a clue.
But what I really want to know is if you other guys with wider tires have noticed this same thing, or if something's wrong with my car. Thanks doods.
And BTW, steered is a word; doods isn't.

I have M pilots and they have been balanced.

Chris, You have a newer ride too, I bet your front end is a bit tighter than our early gen w124's. I am afraid I am going to have to spend some serious time and a few bux rebuilding mine, just to have it new and right. count your blessings
btw - Love the new sig as well.
I'm sure there's plenty of truth to what you guys are saying. But isn't it weird that I didn't have these problems until I lowered my car and put wider tires on it? I guess that could indicate that it's simply an alignment issue. But on a smooth road, i can let go of the steering wheel and the car will go perfectly straight. I don't have problems unless I'm on a road with ruts.
Oh, and myfirstbenz. regarding rubbing issues and rear camber. My car has some very slight rubbing in the front when I turn the wheel close to all the way. I rarely need to do that, so it's not an issue. There are no rubbing issues in the rear. But that leads me to the rear camber- I have a fair amount of room left between the fender lip and my tire. And I know my camber is bad. So I was thinking about getting one of those camber kits. I think I have plenty of room to fix my camber problems. There are three brands that I've heard about:
1. K-mac bushing kit (is this kit adjustable? or is it simply bushings?)
2. Speedybenz adjustable camber kit (a guy who frequents club202.com and is an engineer who makes these- apparently he's extremely difficult to get ahold of, but the quality is fantastic)
3. Benzboy adjustable camber kit (same idea as speedybenz, although I've heard of some people having problems keeping these things put- apparently they can have a mind of their own).
Anybody have other sources? I will probably get this done when I get new tires sometime in the near future, along with a full alignment.

I have heard of k-kmac and speedybenz, and I would give them a try. I just think that it wouldn't hurt, when you have some money freed-up to address these issues, I will on my car because I hate to wear out tires rather than fix the problem at hand. Have you taken it to an alignment shop or just a regular general shop. I hate to say it, but even a place like les schwab (I am not a fan) has a good alignment shop and they can tell you(like they did for my brother for free) with a computer print out what condition your suspension is in and what parts need to be replaced. Their prices were very very fair. For my brother(Benzbro) he got a quote for under 300 for all new tierods and a full allignment. I priced it out and even with my wholesale price connection, it is almost not worth it for the hassle for me to do the work and then drive over to have them do the final allingment.



Perhaps switched to different tires.
