the dealer has noticed some uneven tire wear. i have my winter wheels/tires on right now and am wondering if i should go ahead with the alignment now or wait until i put my summer wheels/tires on. does it make a difference if i wait or should i just go ahead and do the alignment now?

 

Unless your winter and summer sizes are WAY different, which I doubt, the tires should have no impact on your alignment.

 

Well, my winters are 17" (non-staggered) and the summers are the stock (sport) 18" (staggered), what do you think?

 

doesnt matter, if there is uneven wear you should get the alignment checked first on the alignment lift/machine and then get it done if required. There is no charge for alignment check if you plan to get an alignment done by the same shop(in most cases)
