Swap to summer wheel setup - balance/alignment?

[Riggodeaux]

How many miles do you have on your winters? What do they look like, and have you had any of the symptoms previously noted? Particularly if wear/wobble etc., and you have no history of an alignment on the vehicle and it has usual miles [what year is it? mileage?], you might want to have balance on the summers/4 wheel alignment when you have them mounted. All alignments are not the same. I had mine done at a shop with the proper equipment, name of which escapes me at the moment, for a reasonable price.

Removing/replacing wheels does not require an alignment. The balancing is related only to the wheel/tire combo per wheel, and the alignment is related to the suspension. You can swap wheels (that have been balanced when the tires we first mounted to the wheel) as much as your heart desires and need nothing.

With that being said, if you cannot remember when you last had a an alignment it would be a good idea to have it checked.
