I have a '99 B5 with 17x7.5 rims and AVS ES100 225/45/17 tires (35 psi). The inside of the tread is worn much more than the rest of the tire. Currently the car is aligned neutral. Is this normal wear for a Passat or should I have it aligned inwards?

Please comment.

Thanks,

Tom

I don't think you want to change the toe in on your front... please read the following so you understand a little more first. I believe you want to change the camber of the fronts which I think you should have them align your car with a 1BE setting since I don't think you are quite low enough to add custom alignment specs. Have you tried rotating your tires also...?

____________________
Camber:
Camber is the tilting of the wheels from the vertical when viewed from the front of the vehicle. When the wheels tilt outward at the top, the camber is positive (+). When the wheel tilts inward at the top, the camber is negative (-). The amount of tilt is measured in degrees from the vertical. Camber settings influence the directional control and the tire wear.

Too much positive camber will result in premature wear on the outside of the tire and cause excessive wear on the suspension parts.

Too much negative camber will result in premature wear on the inside of the tire and cause excessive wear on the suspension parts.

Unequal side-to-side camber of 1° or more will cause the vehicle to pull or lead to the side with the most positive camber.
______________
Caster:
Caster is the tilting of the uppermost point of the steering axis either forward or backward (when viewed from the side of the vehicle). A backward tilt is positive (+) and a forward tilt is negative (-). Caster influences directional control of the steering but does not affect the tire wear and is not adjustable on this vehicle. Caster is affected by the vehicle height, therefore it is important to keep the body at its designed height. Overloading the vehicle or a weak or sagging rear spring will affect caster.

When the rear of the vehicle is lower than its designated trim height, the front suspension moves to a more positive caster. If the rear of the vehicle is higher than its designated trim height, the front suspension moves to a less positive caster. With too little positive caster, steering may be touchy at high speed and wheel returnability may be diminished when coming out of a turn. If one wheel has more positive caster than the other, that wheel will pull toward the center of the vehicle. This condition will cause the vehicle to pull or lead to the side with the least amount of positive caster.

__________________
Toe:
Toe is a measurement of how much the front and/or rear wheels are turned in or out from a straight-ahead position. When the wheels are turned in, toe is positive (+). When the wheels are turned out, toe is negative (-). The actual amount of toe is normally only a fraction of a degree. The purpose of toe is to ensure that the wheels roll parallel. Toe also serves to offset the small deflections of the wheel support system that occur when the vehicle is rolling forward. In other words, with the vehicle standing still and the wheels set with toe-in, the wheels tend to roll parallel on the road when the vehicle is moving. Improper toe adjustment will cause premature tire wear and cause steering instability.

I doubt your minor drop in suspension height would give you such a huge difference... I have KW coilovers and haven't had a problem with proper rotation of tires and every 6mo an alignment .. nothing out of the ordinary.

Ask for them to setup the alignment for a 1BE setup vs. the 1BA (Euro vs. American) ask for a printout of the final adjustment numbers so that you can judge if you need additional camber, castor or toe for next time.

Since I live in Central NY I rotate my tires every 6 months due the very long and snowy winters and snow tires. The wear on these tires is very also very poor. At most they probably have 15K miles and the wear bars are already showing the tires need replacement. :mad:

Tom,you need to set the toe in slightly. The specs are for .20 degrees toe in. With lowering
springs,the negative camber increases. It may not be excessive,but it will be near the
limits. Camber is not adjustable without the CPP arms,but it can be equalized. With a
little toe-in,the inner tire wear will be less.

I would run between .12-.20 degrees toe in. More than that and the steering will feel
heavy and tramlining will increase. I have messed with mine often,and this feels the best.
A printout of the alignment would help. You can track your camber to see if it is excessive.
The AVS are known for wearing fast,so a longer life tire would help.
