Rear Toe

[tacroteau]

OK I understand the performance importance of inner toe on the rear wheels. However I have just chewed up a set of performance tires in 7,000 miles. Only the inner portion of the tire has been touching, and has made its way to the steel belt after only 7K. This is unacceptable tire wear. As well as once they began to go bald I have had terrible wet traction. My question is, has anyone else had this problem, is the toe/camber adjustable? Or is there a better solution?

is this because of your rear tyre size? I 've got a similiar problem but I thinks its because of the trye size?

No the rear tire size has no bearing toward the camber of the wheel, allthough a significantly larger rim/tire combination will magnify the problem. The problem is that even at the hub, the negative camber is just too much.

How worn is your suspension?

Generally, the toe and camber on these cars is not adjustable - Also, camber will not cause THAT severe of tire wear, thats usually a toe issue.

I ask how the suspension is, because as the springs and shocks sag, the car sits lower than it did at stock heigh - thus increasin the amount of toe in AND negative camber.

If your worried about tire wear, things such as tire pressure, stock tire size and suspension maintenance is absolutely crucial. When all those are correct, you should be looking at 15,000 - 20,000 mi. on a set of 235/45/17s.

If all that is OK, your too aggressive!

Wearing out a set of tires in only 7k miles is rediculous. Its obvious that you have some sort of alignment issue. You say you had performance tires so i would assume they were a good quality name brand tire? When was the last time you had an alignment done? Ever? The rear camber and rear toe on e39 IS adjustable. Contrary to other comments excessive negative camber will wear through tires really fast as well as any toe issues. I would recommend you take the vehicle to a dealership and have an alignment performed. If you take it anyplace else make sure that they are familiar with BMW alignment procedures and MAKE SURE that they do the alignment with the vehicle weighted down. If not then they will set the alignment angles incorrectly. Also be sure to have them check the rear ball joints for starters and then any other suspension components for excessive wear/play. Let us know how it goes.

Wear on the insides of the rear (fronts as well but not as bad) is normal for the E39, especially the ones with the sport package and lower suspension. Although 7000miles is a little too much! What kind of tires did you use? Did you rotate the tires at all, or flip them over if you have directional tires and staggered wheel setups?

I managed to get only 11000miles from a set of Yokohama AVS ES100's which are extremely soft compound tires. But I also "flipped" the tires at about 5000miles when I noticed the inside wear and the noise. I couldn't rotate coz' of directional tires, as well as staggered wheels! So I had to dismount and flip tires.
