I have my 04 coupe lowered on Tein CS coilovers. I recently upgraded my rims/tires from the OEM 18's to the OEM 19's - no change in vehicle height.

I don't think this is necessary, however I wanted to double check to be safe, do I need to do another wheel alignment? Last thing I want is to have bad tire wear on the new 19's.

I've seen some post(s) indicate a wheel alignment is needed if you change your tires.

Thanks!

 

no...it does not affect your suspension geometry by changing tires or wheels...it will affect it if you change your ride height on your coilovers though
