Car still not going straight after alignment
Hello, I just had KW v2 coilovers installed on my 535i and brand new wheels. 19x9.5 and 19x9, 275/35 and 245/40 Michelin Pilot Sport 4S tires. Almost factory sizing for M sport (which mine is). Coilover installation and mounting and balancing were done at a reputable tuner shop. However, they do not do alignment. So a couple of days later, I went to get the alignment. I noticed the car slightly pulling to the right. I took it back to the alignment shop and the tech checked it and said the alignment is fine. So he rotated the front tires, and now it pulls slightly to the left.
I'm confused. Shouldn't brand new parts and a fresh alignment result in a car going straight? The alignment tech he has been doing this for 18 years and it's normal. But it just doesn't seem right to me. He said something about "tire pressure changes while driving." He said it's normal and there is nothing he can do about it. But I'm skeptical and I spent a lot of money. Am I missing something? I have emailed TireRack but they have not responded yet. Any ideas? Update: Called Tire Rack and explained the situation. It's radial pull and they are sending me a new tire. Thanks everyone! Last edited by E90angeleyes; 09-02-2020 at 07:24 PM.. |

did they put weight in the vehicle like most alignments are done with BMW's? there's quite a dozen post on just alignment issues with people with new suspension, new tires, new rims and still the vehicle doesn't drive straight

I'm not sure how much this would affect the pulling, but could there be a caliper or wheel hub going bad causing it to pull in that direction?

It followed the wheel/tire swap side to side. Could be a faulty tire. I'd talk to the tire shop and/or Michelin.
Anything is possible, even though it might not be probably, including defective from the factory. |

lsturbointeg No they did not put weight in. So are you suggesting it is indeed normal? And from my understanding no, the tires are not directional. I just wanna know if it is something I should be worried about or no...
SWFLf10 Got brand new (front) brakes too. Calipers and rotors. Car is 2016, with about 40k miles, no history of accident. I don't think there would be a wheel hub issue. Surly73 Yeah, I've emailed TireRack, but no response yet. Guess I could reach out to Michelin as well. Thanks for the advice. |

For what it's worth, I've been getting alignments at an alignment shop and they've never added the weights. Car tracks straight as an arrow, and tire wear is as even as it gets.

Define what you think a "pull" is. Could it be "drifting" instead? A lot of the times with radial tires you may experience a "radial pull". Cross rotating the front tires usually fixes this issue but it's apparent that now it drifts left. You'll need to talk to the business you purchase the tires from to have them warranty the left tire for you. Don't mess with your alignment specs as when or if you change the front tires you'll then have a real alignment issue

I'm in the same boat. The shop that changed tires and did alignment on my 5 series told me that 1 tire has a defect - radial pull, hence car still drifts to the right. Got a brand new tire, swapped it, car still drifts/pulls to the right. Went for alignment to another shop, that specializes on BMWs, still not straight. Final stop was a dealership. Still having an issue. All specs are green. Drift/pull for me is that car goes straight like 300-400 feet, then pulls to the right. So I kinda have to always steer it(not sure if it's a right word in english) to the left a bit. Not sure what to do at this point. I was told it might be a suspension issue.

The folks with F10s that "pull to the right" no matter what is a different and much more annoying problem. After doing all that work - coilovers, wheels and new 4Ss it must have been very annoying and a let down. I'm curious to hear your impressions of the KWs and how you set them up after it's all sorted. |

As for the KWs, I didn't give any specific instructions to the shop. I just said "not too low" lol. But overall, I'm very happy with the result |

I know it's the sole reason many people get coilovers. For me it was a side effect and not the main reason. Once your tires are sorted, I'm still interested in the rest of the story. |

I don't do any autocross or track days with the car, and even if I did, I never tried it with the previous setup. It's just my daily. All I can say is that the car feels much better. If you have any specific questions I would be happy to answer. But as stated in the earlier paragraph, it's planted and it sticks! So one happy driver here |
