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!

 

Even at stock height your tires will wear a little more on the inner tread
than outer. that's normal.

since you mentioned you didn't change ride height, just leave it alone and
try it. If you get too much tramlining from the wider and shorter
sidewall tires, then dial in a tad more toe-in. maybe 0.2 to 0.3 more
each side.

 

Thanks Ken!
