I am hoping someone can help me figure out why the alignment gets off every time I get the wheels rotated. I had the 350Z wheels on and got her aligned. Put on the winter wheels (stock 17) and now she is pulling to the right again, and the steering wheels is no longer centered.

Any ideas?

 

tire presure?

 

Are tires all same type, size, and tread depth? air pressure?

even the same stated size among different tires or different tread depth on a like tire will be enough difference in overall circumference to cause the car to pull.

 

One "trick" I have always done to compensate for the crown on the road (which will make the car pull right) is to inflate the passanger side tires one psi higher that the drivers side. Works like a charm!

 

All 4 winter tires are the same. The z wheels are staggered but the front match and so do the rear. It happens each time I get them rotated or when I swap wheels. Gets old getting her aligned so often. I should get the life time alignment from firestone.

 

+1 Definately Check you treads.

Say you get it aligned to the winter setup, Does this happen again in the spring when you switch back to the z's or only switching from summer to winter? And how bad is the pulling

If your going to keep it for more than 3-4 years then do the lifetime alignment deal. I swap wheel/tire setups every season also. Aligmnets havent been too bad once I switch over. But I am still tempted to do the lifetime too.

 

It happens anytime the wheels are rotated or changed. Yes with both sets. I am going to get the life time deal.

 

I did the lifetime deal too. Flip your front wheels and see if it pulls the other way. 99% sure it's your tires.
