My latest alignment was last August and everything was working well with my AP2. When I changed out my normal AP2 wheels/summer tires for AP1 wheels/winter tires this December, I noticed the car pulling right during acceleration.

I then checked the tire pressure in all tires and they were all the same. I couldn't really put a finger on a cause, because the car drove fine with the previous Eagle F1/AP2 summer setup.

Now back to current events: the old summer tires were getting pretty bald so I decided to get a set of Michelin PSS and put them on before putting my summer set back on. Unfortunately the car is still pulling to the right while acceleration and then shifts back left (and straight) when I let off or shift. Do I need to get another alignment? Is it possible that they didn't tighten everything on my last alignment? Is it EVEN an alignment problem, considering the car was driving fine before putting the winter setup on?

Possible causes or strange observations:
1. Minor car accident two years ago where my back right hit a barrier at a shallow angle. No reported frame damage, but maybe the frame is slowly getting out of whack?
2. When I had my Eagle F1's on - my rear right tire had about 1-2/32" less tread than my rear left. Both rears were put on at the same time. Maybe this tread different caused the car to drive straight, then when I put on my winter setup and Michelin PSS (both sets with full tread), the car handles differently. If this is the case, why is it doing this?

Thanks guys.

 

I have a similar problem. I have done multiple alignments. The car will go to the right if i let go of the steering wheel. Not noticible if i have my hands on the steering wheel. my tires all have 32 psi in them. I bought brand new rear tires about a month ago. And now my rear right tire is almost done. The outside tread is fine. But the middle of the tire is worn all the way down. The tire is not over inflated. And i have had several alignments done. Still can't figure it out.

I cant afford buying new rear tires monthly. So if i cant figure this out i am going to have to sell the vehicle

 

Anybody with an idea? Someone said something about a front tie rod, but I don't see why that would make the car pull only during acceleration.

 

what are you exact alignment specs before and after your last alignment was performed?

Read this thread if you havent already: https://www.s2ki.com/s2000/topic/760...ys-the-dealer/

 

if ur toe is out of whack it'll cause it to pull, but it'd also do it when driving normally

 

bump

 

something like that happen to me one time with another car. It was the tire itself. When it was in front the car turn it to one side. Then I moved back and the whole car was shaking

 

Still waiting on those alignment specs

 

I had the exact same thing happen to me. Try swapping the rear tires left to right and see if the pull goes in the opposite direction

I recently just changed my diff fluid and put on new wheels and tires. the car is running straight as an arrow now.

 

so I just had another alignment done yesterday. and its still going to the right. as of right now I have 4000 miles on my new tires and the rear passenger tire have about 20% left on it. this is so frustrating
