"To Align or NOT to Align"?

TEST_PILOT4M3 · 11-24-2007, 04:06 PM

I am a new member and I am having a litle drift issue with my new shooz. So I just put on new Beyern Multis 19" et30 x 8.5 in front and 19" x 9.5 et45 rear and wrapped them in Federal 595's Front 225/35 R19 Rear 265/30R19. My issue is there is an ever so slight "drift" to the right on all paved surfaces, and even more noticible at higher speeds. I called my installer back and he said usally with BMW and Mercadies customers have to get slight alignment adjustments due to the high tolerances of the car. So I called the local alignment shop and they tell me that if there wasn't an issue prior to tire instllation then I need to have the rims and tires re balanced and/or checked for damage. I am running 36 PSI all around and can't see any visual issues with the wheels/// Please help with any imputs/comments/advice you guys may have.

I'd do a 4 wheel alignment and if OK re check the tires/rims. My 330i was off both on one front and one rear when we checked it (alignment). I just bought a used 325I for my daughter and not only was the alignment off but all four rims were bent. Damage was not visible on the outside - they were bent on the inner rim - it was easily seen with the eye when off the car. Bent rims tend to give a vibration at a given speed while alignment tends to just pull.

On a side note, your Li (Load index) seems a little low at only 84 on the front. I've been taught that you should never go below the stock Li, in this dimension that is 88.

Good info, I will go have the alignment cheked and see what I can find out.

Roads are usually curved for drainage. The lower profile the tires, the more noticeable the drift gets. Your car perfectly aligned will drift slightly towards the curvature. Make sure its not that effect you are filling.

do the alignment!!!!!!

Going in the AM to get the align checked.

If your car was properly aligned before the wheels then it does not need it now.

Agree. I also believe that due to the crown of the road and the setting of the suspension, cars are designed to have a VERY SLIGHT drift to the right. That keeps the car from inadvertently drifting toward oncoming traffic.

+1. Its more noticeable with the lower profile tires. Plus you went with a weird size. You put more of a staggered setup, will cause more understeer and a bit more pull.

The lower profil of the tire gives more grip to the wheel, then it will follow any deffect of the pavement and gives you the felling of a non alignement!
