New wheels/tires require a four wheel alignment?

[chuck92103]

For those of you who have upgraded your wheels/tires, did you do a four wheel alignment as well?

Is it even necessary when switching tires/wheels?

[Gman]

Nope, no and BMW technicians did not require it.

:stupid: UNLESS you have reason to suspect alignment due to abnormally worn tires prior to the change, etc. Monitor the new setup looking for unusual wear pattern.

Changed rims and tires here, and no need.
